NARRATIVE: Poland and Germany sign historic defense agreement — Europe rearms in fast-forward

Two leaders, one signature, one continent transformed

On June 17, 2026, German Chancellor Friedrich Merz and Polish Prime Minister Donald Tusk signed a bilateral defense pact that European security analysts had been anticipating — and some hoping for — since Russia's full-scale invasion of Ukraine in February 2022. The agreement formalizes a defense partnership between Europe's largest economy and its most strategically positioned eastern anchor, creating a military cooperation framework of a depth and breadth that the two countries had never previously established in their postwar history.

The signing ceremony was deliberate in its symbolism. Germany and Poland share a history that makes their cooperation on defense matters something more than a bilateral transaction — it is an act of historical reconciliation, of shared strategic interest overcoming the weight of the 20th century. Merz and Tusk both acknowledged this dimension explicitly, framing the pact not only as a practical security measure but as a statement about the kind of Europe that their generation of leaders intends to build.

The context: a continent that waited too long to rearm

The backdrop against which the June 17 agreement was signed is one of the most rapid defense spending increases in European history. NATO members have been racing to meet and exceed the 2% of GDP defense spending target — a target that was aspirational for most members before 2022 and has become a floor, not a ceiling, since Russia's invasion. Germany's Zeitenwende — the historic reversal of decades of underinvestment in its military, announced by Chancellor Olaf Scholz in February 2022 — created the political foundation on which Merz has now built a more concrete and more ambitious structure.

Poland had been ahead of the curve. Warsaw was already spending 4% of GDP on defense in 2026 — a level that reflects both its geographic exposure and its reading of Russian intentions. The bilateral pact formalizes what had been an informal alignment: two countries with complementary capabilities, complementary strategic positions, and a shared understanding that Europe's security architecture requires deep German-Polish cooperation at its core.

I have been watching the German Zeitenwende with cautious optimism since 2022. Announcements are easy; structural change is hard. The bilateral pact with Poland is the most concrete evidence yet that Merz is translating the political declaration into an institutional reality. Two countries that once fought the most destructive war in European history are now building a joint defense architecture to prevent the next one. If that is not a European success story, I do not know what is.

Joint defense planning and operational coordination

The core of the bilateral defense pact is a framework for joint defense planning — integrating German and Polish military planning processes in ways that allow the two countries to develop coordinated responses to shared threats rather than parallel but disconnected national plans. This includes joint threat assessments, coordinated force positioning, shared logistics networks, and mutual reinforcement protocols that will allow German forces to operate alongside Polish forces under agreed command arrangements in the event of a crisis.

The operational coordination framework has a specific geographic logic: Poland is NATO's eastern flank in a way that Germany, despite its larger economy and military, is not. Polish territory is where an eastern NATO contingency would most likely unfold. German forces positioned and planned in coordination with Polish hosts are dramatically more effective than German forces operating on different assumptions and timetables. The pact is, at its operational core, about making German power available at the right place and the right time.

Defense industrial integration

Beyond military planning, the pact establishes a comprehensive defense industrial integration framework — creating the conditions for German and Polish defense companies to develop joint production programs, share technology, coordinate procurement, and build the supply chain integration that makes sustained military readiness possible rather than episodic. The Rheinmetall presence in Poland is central to this dimension: the German defense giant has established significant production capacity on Polish soil, creating the geographic and industrial foundation for joint production of ammunition, armored vehicles, and associated systems.

This industrial dimension is not incidental to the pact — it is arguably its most durable element. Military planning frameworks can be revised by future governments; industrial investments in joint production facilities are measured in decades. Rheinmetall's Polish factories will be producing ammunition and armored vehicles long after the politicians who signed this pact have left office. The physical infrastructure of European defense integration is being laid down in Poland, and Germany is its primary industrial partner.

Rheinmetall in Poland is one of the most significant industrial facts in contemporary European security. A German defense company, with German capital and German technology, producing weapons systems on Polish soil — within range of the Ukrainian border. The geometry of this situation would have been unthinkable thirty years ago. Today it is European industrial policy. The speed of this transformation deserves recognition.

Hungary's veto and its end

One of the most consequential elements surrounding the June 17 agreement is the context of the European Peace Facility (FEP) — the EU mechanism holding approximately €6.6 billion in military reimbursements for member states that have supplied weapons to Ukraine. This mechanism had been blocked for months by Hungary's veto under Prime Minister Viktor Orbán, whose deliberate obstruction of EU Ukraine-support mechanisms had become one of the defining irritants of European unity.

The unblocking of the FEP veto — following the political pressure on Orbán generated by the rise of Péter Magyar and his Tisza party — created new political space for EU defense financing decisions that had been paralyzed for too long. The German-Polish pact was signed in a context where this particular obstacle had been removed, and where the EU's collective defense financing architecture could move forward with fewer internal impediments. The timing of the June 17 agreement is not coincidental — it reflects the cumulative effect of structural changes in European politics that Orbán's weakening made possible.

The FEP disbursement debate: Germany-Poland tensions remain

Despite the bilateral defense pact, the underlying Germany-Poland dispute over FEP disbursements was not fully resolved. Berlin argues that the €6.6 billion should flow directly to Ukraine's defense procurement; Warsaw maintains its demand for approximately €450 million in reimbursement for past advances that were never fully covered. The bilateral pact represents a partnership at the level of defense planning and industrial cooperation while leaving the financial accounting dispute unresolved at the EU level.

This coexistence of deep strategic partnership and specific financial friction is characteristic of the German-Polish relationship's current maturity — close enough to sign a historic defense pact, honest enough to acknowledge that the FEP accounting remains a point of contention. Real partnerships can absorb specific disagreements without fracturing the overall relationship. Germany and Poland have demonstrated this capacity, even if the FEP question remains on the agenda for resolution.

The FEP dispute is a symptom of a structural problem in European defense finance: the architecture of collective responsibility was not designed for a situation where some members are paying disproportionately and others are waiting to be reimbursed. Poland has carried enormous costs. Germany has enormous resources. The dispute is about fairness within solidarity, not about whether solidarity should exist. That distinction is worth preserving in how we discuss it.

From 1.2% to a defense-serious nation

The German Zeitenwende announced in 2022 represented the most dramatic shift in German security policy since reunification. Germany had spent decades at 1.2–1.5% of GDP on defense — a level that reflected both the pacifist cultural legacy of World War II and a political calculation that American security guarantees made German military investment less urgent. The €100 billion special defense fund announced by Scholz in 2022 was the initial down payment on reversing this legacy.

Under Chancellor Merz, the Zeitenwende has deepened into structural reform: permanent increases in the defense budget beyond the one-time special fund, reform of the Bundeswehr's procurement and training systems, integration of German defense industry into EU collective production frameworks, and — most concretely — the kind of bilateral defense partnership formalized with Poland on June 17. The question that shadowed the Zeitenwende from its announcement — whether it was a political declaration or a genuine structural transformation — is being answered, incrementally but consistently, in favor of the latter.

The historical dimension: weight of the 20th century lifted

For a country that invaded Poland in 1939 and caused the death of six million Polish citizens, signing a bilateral defense pact with Warsaw carries a historical weight that no amount of diplomatic language can fully normalize. Merz addressed this directly at the signing ceremony — acknowledging the historical dimension without dwelling in it, recognizing that the pact is possible precisely because Germany has spent seven decades processing its historical responsibility and building a democratic state that Poland can trust as a partner.

This dimension is not merely ceremonial. Polish public opinion on German defense cooperation has been, historically, complex — shaped by the memory of German aggression and more recently by concerns about Germany's pre-2022 energy dependence on Russia and the hesitancy that dependence created in Berlin's Ukraine policy. The June 17 pact is, in part, Germany's answer to those concerns — a concrete demonstration that post-Zeitenwende Germany is a reliable strategic partner in a way that pre-2022 Germany was not.

The moment of Merz and Tusk signing this pact will be, I think, remembered as one of the genuinely significant images of this era. Two countries that fought the most destructive bilateral conflict in European history, standing together to build a common defense against the threat that is, this time, coming from the east. History does not repeat, but it rhymes with enough force to move you. This moment moved me.

The logistics hub for Western support to Ukraine

Poland's role in the Western support architecture for Ukraine has been foundational since February 24, 2022. Polish territory is the primary logistics corridor through which weapons, ammunition, and equipment flow from Western production and stockpile to Ukrainian front lines. Polish airports have processed billions in military equipment. Polish railways have carried armored vehicles and artillery systems. Polish customs have processed the humanitarian and military flows that keep Ukraine supplied. Without Poland's territory and cooperation, Western military support to Ukraine would be logistically impossible at anything approaching current scale.

This logistics function gives Poland a strategic centrality in the current conflict that its population size and GDP do not fully explain. Tusk has used this position to advocate consistently for stronger Western support to Ukraine, for faster movement on NATO membership discussions, and for the kind of deep bilateral relationships — with Germany, France, the UK, and the US — that amplify Poland's voice in European councils beyond its formal voting weight.

Poland's defense spending as a European leadership act

Poland's 4% of GDP defense spending in 2026 is not simply a national security decision — it is a deliberate act of European leadership that Tusk and his government have consistently articulated as such. By demonstrating that a medium-sized EU member state can sustain defense spending at this level without economic collapse, Poland is making the case to its more hesitant partners that the cost of serious defense investment is manageable, that the political will to make it is available if leadership chooses to exercise it, and that the alternative — light spending in the hope that Russian aggression will remain geographically bounded — is a bet that the evidence does not support.

Poland's defense spending is a form of argument, not just policy. The argument is: this is what taking the threat seriously looks like. The bilateral pact with Germany formalizes a partnership between Europe's most enthusiastic defense spender and its largest economy — a combination with the potential to reshape the continent's security architecture from the inside out.

Tusk has staked his government's identity on two things: rebuilding Polish democratic institutions and making Poland the indispensable partner in European defense. Both goals serve the same deeper purpose — demonstrating that a strong, democratic Poland aligned with European values is better for Poles than the illiberal, Russia-adjacent posture of the PiS era. The bilateral pact with Germany is the capstone of this argument. I hope Polish voters continue to choose it.

What Rheinmetall's Polish presence means

Rheinmetall's investments in Poland represent one of the most strategically significant industrial decisions in contemporary European defense. The German defense company has established production facilities on Polish soil for 155mm artillery ammunition, Lynx infantry fighting vehicles, and associated systems — creating a production capacity that serves NATO's eastern flank needs while simultaneously embedding German industrial investment in Poland's defense economy in ways that deepen the bilateral relationship beyond policy agreements.

The ammunition production capacity is particularly significant. 155mm NATO-standard shells are the most critical and most constrained munition in the current conflict — both for Ukrainian forces and for NATO member states seeking to rebuild their own stockpiles. Rheinmetall's Polish facilities produce this ammunition closer to the front lines than any other major European producer, reducing logistics costs and time while contributing to the European defense industrial base expansion that NATO has identified as a strategic priority.

The industrial strategy behind the geography

Rheinmetall's presence in Poland is part of a broader European defense industrial strategy that the bilateral pact formalizes and deepens. The strategy involves distributing production capacity across Alliance territory rather than concentrating it in Germany alone — creating resilience, reducing single points of failure, and building the political economy of defense investment in countries that have the strategic motivation to sustain it. Poland's high defense spending makes it an ideal host for defense industrial investment; its geographic position makes the production output directly useful for the most urgent current requirements.

The pact includes provisions for deepening Rheinmetall's Polish investment and for expanding joint German-Polish defense production to additional systems. The industrial relationship will outlast any government on either side. It represents the most durable form of European defense integration: the kind written not in treaty language but in factory floors, production contracts, and the long-term supply chain relationships that create genuine interdependence.

A weapons factory built close to the front line of an ongoing conflict is both a practical decision and a statement. Rheinmetall is saying: we believe Ukraine will need ammunition for the foreseeable future, and we will be positioned to provide it. That industrial conviction, expressed in capital investment, is more credible than any summit declaration. Money invested in production capacity cannot be recalled by a political speech.

Accession negotiations opened June 2026

The German-Polish defense pact was signed in a context where EU accession negotiations with Ukraine had formally opened in June 2026 — a milestone that both Merz and Tusk had individually and jointly advocated. The intersection of the bilateral defense pact and the accession opening reflects a coherent strategic vision: an Ukraine that is simultaneously receiving military support from its European partners, integrated into European reconstruction financing, and moving along the institutional pathway toward EU membership is an Ukraine whose strategic future is progressively more secure.

Germany and Poland are the two EU members most directly relevant to Ukraine's accession path — Germany as the bloc's largest economy and largest contributor to EU institutional processes, Poland as Ukraine's largest land-border neighbor and most vocal accession advocate. Their joint advocacy, formalized in the defense pact's language about European integration, gives the accession process a bilateral political engine of considerable power.

The NATO accession parallel

The EU accession opening runs parallel to ongoing discussions about Ukraine's NATO membership — discussions that the German-Polish pact also addresses, with both countries reaffirming their support for Ukrainian membership and their commitment to building the bilateral security guarantees that fill the gap until formal accession becomes possible. Germany's evolution on this question is particularly significant: Berlin's willingness in 2026 to advocate clearly for Ukrainian NATO membership represents a departure from the more hedged position it held in 2022 and 2023.

The combined German-Polish advocacy for both EU and NATO accession creates a powerful diplomatic alignment at the heart of European institutions. It does not guarantee Ukrainian accession on any specific timeline — the consensus requirements in both organizations are real. But it fundamentally changes the political geometry of the accession debate, making the skeptical positions harder to maintain in the face of joint German-Polish pressure.

I want to live to see Ukraine's accession to both the EU and NATO. I want to see the flag ceremonies, the institutional welcomes, the parliamentary votes. I want to see a Ukrainian president speaking to the European Parliament as a member, not a guest. The bilateral pact between Germany and Poland does not make that day certain. But it makes it closer. And closer, right now, is everything.

From aggression to alliance: the arc of reconciliation

The story of German-Polish reconciliation since 1945 is one of the most remarkable achievements of the European project — a deliberate, sustained, intergenerational process of acknowledgment, restitution, educational reform, and institutional relationship-building that gradually replaced the memory of occupation and extermination with the habits of partnership. This process was never linear and never complete; the historical wounds are deep enough that they periodically resurface in bilateral political discourse and in the cultural memory of both peoples.

The June 17, 2026 defense pact is the most concrete military expression of this reconciliation — a statement that Germany and Poland have arrived at a relationship of sufficient trust to entrust their national security to each other's cooperation. This did not happen automatically. It happened because generations of political leaders on both sides chose to do the difficult work of building it, and because the EU's institutional framework provided the architecture within which bilateral trust could accumulate over decades.

The Merz-Tusk relationship as a driver

The specific personal and political relationship between Merz and Tusk has been a significant driver of the bilateral pact's depth and timing. Both leaders are of a generation that has absorbed the European project's lessons about what German-Polish cooperation can mean, both are politically aligned on the fundamental questions of Ukraine support and European defense investment, and both have the political standing in their respective domestic contexts to take the pact forward without coalition fragility undermining the commitment.

Leadership chemistry matters in international relations, even when structural forces are the primary drivers. Merz and Tusk's alignment on the strategic vision behind the pact has accelerated a process that could have been slower, more hedged, or more diluted by domestic political compromises. The pact is what it is, in significant part, because of who the two men are and what they choose to prioritize.

Merz and Tusk will not be prime ministers forever. The institutions they are building — joint planning frameworks, industrial partnerships, bilateral treaty commitments — need to be designed to outlast them. I hope they are thinking about the institutional durability of what they are creating, not just its political significance in the current moment. The best acts of statesmanship are the ones that constrain future governments to maintain what current governments built.

A continent reordering its defense center of gravity

For decades, European defense discussions centered on the Franco-German axis — the bilateral relationship between France and Germany that drove European integration from its post-war origins through the Maastricht era and beyond. The German-Polish pact does not replace this axis; the Weimar Triangle of Germany, France, and Poland remains an important format. But it supplements it with an eastern dimension that the Franco-German axis always lacked — a partnership between Germany and the country that sits directly at NATO's eastern frontier.

This reorientation reflects the shift in Europe's strategic geography that Russia's 2022 invasion made unmistakable: the threat axis runs east-west, and the eastern flank states bear the highest exposure. A European defense architecture that does not put deep German-Polish cooperation at its core is an architecture optimized for the last century's threats, not the current one. The June 17 pact is the institutional expression of this geographic reckoning.

The ripple effects on other European defense relationships

The German-Polish bilateral pact will have ripple effects across European defense relationships. It creates pressure on France to deepen its own eastern European defense partnerships — including with Poland through the Weimar format and with Ukraine through bilateral security agreements. It creates a template that other Central European countries can observe and seek to replicate with their own bilateral partners. And it creates expectations in NATO that Germany has now, formally and bilaterally, committed to the eastern flank in ways that its pre-2022 posture never did.

The ripple effects on the broader European defense landscape will take time to manifest fully. But the structural logic is clear: when the continent's largest economy and its most defense-serious eastern member formalize a deep bilateral defense partnership, it changes the geometry of every other bilateral and multilateral defense relationship in Europe.

Europe is rearming. Not in the panicked, incoherent way of a continent responding to immediate crisis — but in the deliberate, institutional way of a continent that has finally acknowledged that its post-Cold War defense holiday is over. The German-Polish pact is one of the clearest expressions of this. It will take years to be fully operational and decades to mature. But it is being built. That is what matters now.

A rear architecture for Ukrainian security

For Ukraine, the German-Polish bilateral defense pact represents the construction of a rear security architecture — a partnership between two of its most important Western supporters that deepens the material, industrial, and institutional basis for sustained support. A Germany that is more deeply invested in Poland's defense and more closely integrated with Polish military planning is a Germany with a more immediate stake in the stability of NATO's eastern flank — and therefore in Ukraine's continued resistance.

The industrial dimension is most directly relevant to Ukraine: Rheinmetall's Polish production capacity produces ammunition and vehicles that flow toward Ukrainian forces; the bilateral industrial framework creates pressure to expand this production further; and the defense planning integration between Germany and Poland strengthens the logistics infrastructure through which Western military support reaches Ukraine. The pact is not about Ukraine directly, but its effects on Ukrainian security are real and significant.

The accession pipeline as the ultimate deliverable

Beyond immediate military implications, the German-Polish pact's joint advocacy for Ukrainian EU and NATO accession represents the most important long-term contribution to Ukrainian security. Membership in both institutions would provide the deterrence guarantees, the institutional integration, and the economic framework that would make a recurrence of Russian military aggression prohibitively costly. The bilateral advocacy of Europe's most important eastern partnership for Ukrainian accession is the clearest possible signal to both Moscow and Kyiv about where Europe's political center of gravity has moved.

Ukraine's ultimate security guarantee is not a bilateral defense pact, however historic. It is membership in the institutions that make aggression against any member a suicidal act. The German-Polish pact is a step on the path to building the political conditions for that membership. It is not the destination — but it is movement, clearly directed, structurally significant, and irreversible in its institutional logic.

I think about what a Ukrainian soldier in 2026 makes of the German-Polish defense pact. Probably not much — there are more immediate things to think about. But in twenty years, in a Ukraine that is a NATO member and an EU member, someone will trace the institutional history and find this pact near the beginning of the chain that made it possible. Historical significance is often invisible from inside the moment that contains it.

Russia and the European power shift

Russia reacted to the German-Polish defense pact with a combination of hostile statements and military posturing. Kremlin spokesman Dmitri Peskov characterized the agreement as proof of "NATO escalation at Russia's borders" — standardized propaganda language that Moscow applies to any Western defensive cooperation. This narrative is false — the German-Polish pact is defensive, not offensive — but it serves the Russian information agenda.

Russia's reaction is in fact the best indicator that the pact is effective. If the agreement had no strategic significance, Moscow would not have commented on it with such emphasis. Russian nervousness about German-Polish defense cooperation says that Putin sees this pact as a threat to his long-term strategy — keeping Europe divided, dependent, and incapable of producing a coherent military response to his aggressions.

The geopolitical significance for Kaliningrad

The German-Polish defense pact carries particular significance in the context of the Russian exclave of Kaliningrad. This enclave, wedged between Poland and Lithuania, is a Russian forward military base in central Europe and a strategic vulnerability for NATO. Enhanced military cooperation between Germany and Poland strengthens the Alliance's defense capacity in this sensitive zone — without constituting an offensive threat against Russian territory.

The Kaliningrad question is a discreet but real component of the security relationship between Poland and Germany. Poland wants the Alliance to be able to defend the Suwalki corridor — the land area between Kaliningrad and Belarus that connects the Baltic states to the rest of NATO. The June 17 agreement strengthens this defensive capacity without ever making it explicit in public.

Putin had planned on a divided, disarmed Europe, incapable of collectively responding to his ambitions. In 2026, he is watching a Europe that signs bilateral military agreements, doubles its defense budgets, and forms a coalition of support for Ukraine stronger than it was two years ago. The Russian calculation failed. The German-Polish pact is another direct demonstration of that failure.

Tusk: an agreement in the direction of history

Polish Prime Minister Donald Tusk hailed the June 17, 2026 agreement as "an accord in the direction of history." For Tusk, this agreement is the culmination of a conviction he has long defended: that Poland and Germany share fundamental strategic interests that must translate into concrete cooperation, not merely friendly declarations. His phrase "direction of history" says something important: Tusk sees the pact not as a turning point but as a coherence — the logical continuation of European reconciliation begun after 1945.

For Poland, the agreement also represents recognition of its growing military power. Warsaw is no longer the junior partner seeking protection — it is a major contributor to European security that negotiates as an equal with the continent's largest economy. This recognition matters for Polish public opinion and for the international credibility of Tusk's coalition government.

Merz: the Zeitenwende takes concrete form

For Chancellor Friedrich Merz, the June 17 agreement is the concrete translation of the Zeitenwende — the historic turning point announced by his predecessor Scholz in 2022. Merz, more openly Atlanticist and pro-defense than Scholz, has accelerated the transformation of German security policy since taking office. The agreement with Poland is one of its most visible expressions.

Merz also manages German domestic politics — a population not entirely convinced of the usefulness of increased military spending, and coalition partners with different priorities. The bilateral agreement with Poland allows him to show concrete results from his active security policy. That is domestic politics as much as international diplomacy.

I watch Merz and Tusk sign this agreement and think of all their predecessors who did not dare — or did not want — to go this far in military cooperation between their two countries. History gives them tools their predecessors lacked: the war in Ukraine as catalyst, the maturity of German-Polish reconciliation as foundation. These are two pragmatic heads of government seizing the moment. That is real leadership.

What the pact does not resolve

The German-Polish defense pact is important — but it does not solve every challenge. It does not compensate for the lack of an integrated European command architecture — German and Polish forces remain under separate national commands, with NATO as the common coordination framework. It does not resolve the occasional disputes over Ukrainian contributions — the €6.6 billion FEP dispute being a recent example. And it does not change the fact that both countries' military capabilities take years to build.

The industrial challenges are particularly significant. Creating new production capacity for ammunition and military equipment takes time — two to five years for a new production line. In the interim, Ukraine needs equipment and ammunition now. The June 17 agreement prepares the future — but it does not resolve the urgency of the immediate present.

The political durability of the agreement

A bilateral agreement depends on the political stability of the two governments that signed it. Merz and Tusk govern in political contexts that can evolve. In Germany, Merz's coalition faces the rise of the populist AfD, skeptical of aid to Ukraine. In Poland, the Tusk coalition must manage a PiS opposition that could return to power in future elections. The institutional durability of the agreement — its inscription in permanent structures that outlast the individuals — is therefore a crucial issue.

Both governments are aware of this. The agreement is designed to create permanent institutional structures — coordination headquarters, industrial commissions, regular consultation mechanisms — that will survive political changes. This institutionalization is one of the forms of wisdom that modern bilateral agreements have learned from past mistakes.

The durability of defense agreements in the face of political change — that is the question I always ask. Military structures resist changes of government better than political promises. If the German-Polish pact creates concrete structures — joint staff, industrial programs, regular exercises — it will survive Merz and Tusk. That is the real question: not the signatures of June 17, but what remains on June 17 of next year.

Every agreement strengthens collective deterrence

The German-Polish defense pact is not an isolated event — it fits into a growing web of bilateral and multilateral agreements that strengthen the West's deterrence posture against Russia. Ukraine's bilateral defense agreements with the UK, France, Germany, and the United States. NATO's strengthened presence on the eastern flank. Increased defense spending. Industrial rearmament. Each element adds to a collective posture that tells Putin: we will be here.

Deterrence works when it is credible — when the adversary is convinced that the cost of aggression will exceed the benefits. Russia calculated in 2022 that the West would lack the will to resist. It was wrong. In 2026, the evidence of that will is accumulating. The German-Polish pact is one of those pieces of evidence. It does not guarantee peace — but it makes peace more probable by raising the cost of any future aggression.

The prospect of peace: what role for this agreement

Paradoxically, a solid defense agreement can contribute to peace by creating the conditions for negotiation from a position of strength. A Ukraine fighting with the support of a reinforced military coalition — of which the German-Polish pact is a pillar — is a Ukraine that negotiates from strength. The just peace that Zelensky defends cannot be obtained from a position of military weakness. Strengthening Ukraine's military position means strengthening its diplomatic position.

Those who criticize the German-Polish pact — and all military reinforcement — on the grounds that it delays peace have the logic inverted. Lasting peace in this war will not come from an exhausted Ukraine accepting terms imposed by Putin. It will come from a balance of forces that makes Russian aggression unsustainably costly and reasonable negotiation in Russia's own interest. The June 17 agreement works toward that end.

Some say that arming leads to war. True — in certain contexts. But in the current context, where Russia has already invaded, where the war is already here, arming Ukraine and NATO leads to a possible peace. Strong deterrence is the condition for balanced negotiation. The German-Polish pact does not prolong the war — it creates the conditions for its honorable end.

What was signed and what it means

The German-Polish bilateral defense pact of June 17, 2026 is a turning point in European defense history — not because it solves every problem, resolves every bilateral tension, or guarantees any specific military outcome. It is a turning point because it establishes, formally and institutionally, a deep defense partnership between the continent's largest economy and its most defense-serious eastern anchor, at a moment when the strategic rationale for such a partnership has never been clearer and the political will to create it has finally materialized.

The rearmament that was always necessary

Europe has been rearming. The German-Polish pact is the clearest institutional expression of a rearmament that is not a choice but a necessity — the belated recognition that the continent's post-Cold War peace dividend was borrowed time, that Russian imperialism did not end with the Soviet Union's dissolution, and that the European security architecture requires the same seriousness of purpose that the Cold War demanded. June 17 is not the beginning of this reckoning. But it may be the moment when the reckoning became structural enough to be irreversible.

I end this narrative with a question left open: in ten years, will June 17, 2026 be the beginning of an integrated and credible European defense — or merely another episode in the long history of unfulfilled promises? The answer depends on what Merz, Tusk, and their successors do with this foundation. They have laid the first stone. The house remains to be built.
