Rubio and Wadephul redraw NATO's military burden

Introduction: Washington wants Europe to finally pay its fair share

A meeting in Washington ahead of the Ankara summit

US Secretary of State Marco Rubio met on June 29, 2026 with German Foreign Minister Johann Wadephul in Washington, a meeting meant to coordinate positions ahead of the NATO summit in Ankara, scheduled for July 7 and 8, according to reporting from Yenişafak and The Hindu.

The two diplomats discussed a new burden-sharing arrangement within the Atlantic Alliance, a strategy explicitly designed to have European partners take on primary responsibility for their own conventional defense.

Diplomatic language hiding a strategic revolution

This column examines what this concept of burden shifting actually means for the future of European security, and why this bilateral meeting deserves far more attention than the simple diplomatic statement that followed it.

According to State Department spokesperson Tommy Pigott, the two ministers also reaffirmed their shared commitment to the security of the Strait of Hormuz and to preventing Iran from acquiring nuclear weapons.

The concept of burden shifting, a doctrine taking hold

From 2% to 5% of GDP, a historic budgetary escalation

Since the Hague summit in June 2025, NATO allies, with the exception of Spain, have committed to investing 5% of their GDP annually in defense and security by 2035, with 3.5% devoted directly to core defense needs and 1.5% to related areas such as cybersecurity and resilience.

This doubling of the old 2% of GDP target, set at the Wales summit in 2014, represents a major budgetary transformation for all twenty-three European member states of the Alliance, several of which will have to more than double their current military spending.

Burden shifting becomes official Alliance doctrine

According to an analysis published by CEPA, burden shifting has now become an official doctrine of the Atlantic Alliance, which puts laggard countries in a particularly uncomfortable position as the Ankara summit approaches.

This doctrinal shift reflects years of steady American pressure, with the Trump administration having made the equitable sharing of defense costs one of its absolute priorities toward its European NATO partners.

Canada, the Alliance's historic laggard

Chronic delay despite repeated pressure

According to an analysis by the Anadolu agency, Canada remains historically the partner furthest behind on its burden-sharing commitments, having systematically failed to reach the old 2% target despite years of repeated pressure from Washington.

This persistent Canadian lag, documented year after year, illustrates the real limits of American diplomatic pressure when it runs up against internal budgetary constraints and national political priorities that differ from Washington's.

A turning point in 2025, every member finally hits 2%

Notably, according to this same analysis, the year 2025 marked the first time since the 2% of GDP target was codified at the Wales summit in 2014 that all 32 NATO member countries reached or exceeded that threshold, a significant milestone despite the fact that the target had already been doubled in the meantime.

This achievement, though belated and now superseded by the new 5% target, shows that sustained American pressure, combined with the very real Russian threat in Ukraine, can genuinely transform the budgetary behavior of European countries over the long run.

Turkey, a strategic host with particular ambitions

Ankara wants its place in Europe's defense industry

According to a report by the Atlantic Council, Turkey remains the only major European NATO ally with an advanced defense industry that is still excluded from the European Union's main funding and procurement mechanisms, a situation Ankara wants to correct at this summit it is hosting.

This persistent exclusion of Turkey from European industrial frameworks, despite its recognized production capabilities, particularly in the field of drones, illustrates the complex tensions between NATO membership and integration into specifically European defense structures.

President Erdogan, host of a summit with high symbolic stakes

Turkish President Recep Tayyip Erdogan is hosting this summit in a context where Turkey is actively pushing for a fairer burden-sharing arrangement and strengthened European security, a position that paradoxically aligns with American demands while also serving Turkish industrial interests.

This convergence of interests between Ankara and Washington on burden sharing, though driven by different considerations, could facilitate the adoption of concrete measures at the summit, with Turkey having every interest in seeing its own industrial capabilities called on more by its allies.

Secretary General Rutte, conductor of the transition

Billions in defense contracts announced in Ankara

NATO Secretary General Mark Rutte announced, according to reporting from US News, that tens of billions of dollars in defense-related contracts would be announced at the Ankara summit, a strong signal of the scale of the industrial mobilization underway within the Alliance.

This announcement of massive contracts is meant to concretely demonstrate allies' commitment to the spending targets set in The Hague, turning abstract budgetary promises into tangible, verifiable industrial investments.

A show of unity despite real internal tensions

According to comments from Rutte reported by the Washington Times, allies remain united around the imperative of investing in their own security, committed to an equitable sharing of responsibilities, rhetoric of unity that nonetheless masks very real tensions between countries over the pace and scale of this budgetary transition.

This skillful handling of institutional communication by the Secretary General reflects the political experience of Rutte, a former Dutch prime minister, who must juggle American demands, varying European budgetary capacities, and the need to project an image of cohesion in the face of Russia.

The PURL mechanism, funding Ukrainian weapons differently

More than 5.5 billion dollars mobilized for Ukraine

According to the detailed report from the Atlantic Council, the PURL mechanism, launched after the Hague summit to fund the purchase of essential American military equipment for Ukraine, mobilized more than 4 billion dollars by December 2025, followed by an additional 1.5 billion dollars in 2026.

This voluntary mechanism involves the participation of twenty-five NATO member countries as well as three partner countries, illustrating a collective funding approach that spreads the cost of military support for Ukraine beyond the United States alone.

An expected expansion at the Ankara summit

Discussions in Ankara are expected to focus on expanding participation in the PURL mechanism and on establishing a robust multi-year funding mechanism, with a clearly defined burden-sharing framework to ensure long-term support for Ukraine beyond 2027.

This planned expansion of the PURL mechanism directly addresses concerns about the potential depletion of American air-defense stockpiles, a consequence of the war with Iran, which could limit the availability of missiles and interceptors for Ukraine in the months ahead.

Germany's position, between Atlantic loyalty and autonomy

Wadephul stresses the importance of the transatlantic partnership

Before departing for Washington, Minister Wadephul emphasized, according to Reuters Germany, that the United States remains Germany's most important partner outside Europe, a statement that reflects Berlin's determination to preserve the transatlantic relationship despite tensions over burden sharing.

This German insistence on Euro-Atlantic security reflects a clear understanding in Berlin that the Alliance's cohesion in the face of Russia depends directly on the continued strength of the transatlantic link, despite current budgetary friction.

A packed agenda beyond the NATO question alone

After his meeting with Rubio, Wadephul was scheduled to travel to Paraguay to take part in the Mercosur summit, a packed diplomatic agenda that illustrates the scale of the international responsibilities now shouldered by the new German diplomacy across several continents simultaneously.

This all-azimuth diplomacy from Berlin, combining NATO, Middle Eastern and South American files, demonstrates a German ambition to play a leading role on the international stage, well beyond its traditional role as a discreet European economic partner.

The Ukrainian file, the common thread through every discussion

Coordinated pressure to push Moscow toward negotiations

According to Devdiscourse, the stated goal of this new burden-sharing arrangement is to secure stable, long-term support for Ukraine, in the hope that this demonstration of Western resolve will push Moscow to end hostilities and engage in genuine peace talks.

This strategic logic rests on a simple but risky bet: convincing the Kremlin that the West can support Ukraine indefinitely, at a sustainable cost for each individual ally, thereby making any Russian war-of-attrition strategy structurally doomed to fail.

Rubio and Wadephul reaffirm unwavering support for Kyiv

The two ministers reaffirmed, according to Yenişafak, their unwavering support for the goal of a lasting peace between Russia and Ukraine, a diplomatic formulation that suggests the ongoing peace talks have not yet produced a satisfactory outcome for the two Western capitals.

This language of unwavering support, repeated tirelessly at every major bilateral meeting, is meant both to reassure Kyiv and to send a message of firmness to Moscow, which continues to test Western resolve with sporadic offensives on the ground.

The Iranian file, a cross-cutting concern

Hormuz and Iran's nuclear program, two shared priorities

The discussions between Rubio and Wadephul also covered the need to maintain secure transit through the Strait of Hormuz and to permanently prevent Iran from developing or acquiring a nuclear weapon, two strategic priorities that directly align with European and American security interests.

This convergence on the Iranian file comes in the wake of recent diplomatic efforts to finalize a peace agreement between the United States and Iran, a fragile process that continues to directly influence broader NATO strategic calculations.

The impact of the Iranian war on Western military stockpiles

The recent war with Iran significantly drew down American air-defense stockpiles, a reality that now complicates Washington's ability to keep generously supplying Ukraine with missiles and interceptors, reinforcing the urgency of the debate over the European burden-sharing.

This very real material constraint shows just how much the multiple fronts of confrontation with the China-Russia-Iran-North Korea axis are placing cumulative pressure on Western military capabilities, making a substantial and rapid European rearmament more urgent than ever.

European criticism of burden shifting

Concern over the pace imposed by Washington

Despite officially endorsing the new spending targets, several European diplomats privately express concerns about the extremely fast pace imposed by Washington for this transition to the 5% of GDP target, with some estimating that this acceleration could weaken other essential national budgetary priorities.

These reservations, rarely voiced publicly to avoid undermining the Alliance's displayed unity, nonetheless reveal persistent structural tensions between the real budgetary capacities of certain European countries and the strategic ambitions set collectively in The Hague and soon in Ankara.

The transatlantic balance of power, still asymmetric

This burden-sharing dynamic, though presented as a balanced collective effort, actually reflects a balance of power that remains clearly asymmetric in Washington's favor, with the United States retaining the ability to unilaterally set the timeline and targets that its European allies must then strive to meet.

This persistent asymmetry, if not managed with sufficient diplomatic tact by Washington, could eventually fuel European resentment capable of weakening the Alliance's cohesion at the precise moment when Western unity is most needed against the combined threats of Russia, China and Iran.

Europe's defense industry, a potential winner of this transition

An opportunity for the continent's arms manufacturers

This massive budgetary surge represents a historic opportunity for Europe's defense industry, with several countries now favoring a buy-European approach rather than exclusive dependence on traditional American suppliers, a trend documented by the Atlantic Council report.

This industrial reorientation, if it holds over time, could significantly strengthen Europe's strategic autonomy in the long run, gradually reducing the continent's dependence on American military equipment, a goal several European capitals have pursued for years.

NATO-EU industrial cooperation still to be built

The Atlantic Council report explicitly recommends creating a defense industrial cooperation mechanism including NATO members that are not EU members, a direct reference to Turkey's particular situation but also to the post-Brexit United Kingdom.

This recommendation illustrates the growing institutional complexity of the Western defense architecture, where NATO and European frameworks must now better align to avoid costly duplication and maximize the collective effectiveness of the announced defense investments.

What this meeting reveals about the new American doctrine

A strategic rebalancing openly embraced by Washington

This meeting between Rubio and Wadephul confirms a fundamental trend in American foreign policy under the Trump administration: an openly embraced rebalancing of collective security responsibilities, in which European allies must now shoulder a far larger share of the burden of their own conventional defense.

According to the European Parliament report, the US Army command in Europe indeed indicated in early June that Washington would proceed with a downsizing of its contributions to NATO's force model, an official confirmation of this strategic reorientation already widely anticipated.

A 2027 deadline for European conventional responsibility

According to this same report, the United States reportedly expects European allies to assume primary responsibility for the bulk of NATO's conventional defense in Europe by 2027, an extremely tight timeline that imposes an accelerated transformation of European military capabilities.

This tight deadline places considerable pressure on European defense planners, who must now speed up weapons and military recruitment programs that traditionally take years, even decades, to fully bear operational fruit.

The revision of America's military posture in Europe

Hegseth announces a full review of US forces

US Secretary of War Pete Hegseth announced, according to the European Parliament report, a complete review of the posture and positioning of American forces in Europe, with conclusions expected by the end of 2026, a process that could lead to significant withdrawals of American troops from the continent.

This announcement is fueling legitimate concern among several European allies, particularly those on the front line facing Russia, such as the Baltic states and Poland, who fear that a withdrawal that comes too fast could create a dangerous security vacuum before European capabilities are fully operational.

A delicate balance between disengagement and collective security

Washington will have to strike an extremely delicate balance between its legitimate desire to reduce its direct military commitments in Europe and the absolute necessity of maintaining credible deterrence against a Russia that remains militarily mobilized and politically determined to test the limits of Western resolve.

A poorly calibrated or overly hasty American withdrawal could send a dangerous signal to Moscow, suggesting a window of strategic opportunity the Kremlin could be tempted to exploit before Europe has completed its promised military buildup.

The Baltic states and Poland, on the front line of concern

A geographic proximity that changes everything

For the Baltic states and Poland, sitting directly on the border with Russia or its Belarusian ally, the question of burden sharing and the timeline of an American withdrawal is not an abstract budgetary exercise, but a matter of immediate national survival that justifies particular vigilance toward any change in NATO's posture.

These frontline countries have already far exceeded NATO spending targets, with some devoting more than 4% of their GDP to defense, a considerable budgetary effort that contrasts sharply with the historic lag of other European members further removed from the direct Russian threat.

A constant push to keep American troops in place

Baltic and Polish leaders keep making discreet but insistent appeals to Washington to ensure that any revision of America's military posture in Europe preserves a sufficient level of presence on the eastern flank of the Alliance, where deterrence against potential Russian aggression remains most critical.

This constant concern illustrates a real geographic fault line within the Alliance between countries that see the Russian threat as existential and immediate, and those for whom it remains a more distant, abstract concern, a divergence that complicates negotiating a common doctrine in Ankara.

Conclusion: Ankara, a moment of truth for the Atlantic Alliance

A summit of implementation more than innovation

According to the analysis by CEPA, the Ankara summit is not expected to produce major innovations or radical policy changes, with NATO officials presenting it mainly as an implementation summit following up on the commitments made in The Hague, though enhanced political consultation on the southern flank could emerge as a notable development.

This meeting between Rubio and Wadephul, along with the many similar preparatory discussions among other allies, sketches the outlines of an Atlantic Alliance undergoing full structural transformation, where burden sharing stops being a diplomatic slogan and becomes a concrete budgetary and industrial reality.

Western unity remains the only credible response to combined threats

Facing Russia in Ukraine, Iran in the Middle East, and China watching closely for any sign of Western weakness from the Indo-Pacific, this reorganization of NATO's burden sharing represents a strategic necessity rather than a mere trade dispute among allies.

The Ankara summit will determine whether this Alliance manages to turn its budgetary commitments into real military capabilities, or whether persistent transatlantic tensions over the pace and terms of this transition end up weakening collective cohesion at the worst possible moment.

Columnist's transparency note

My acknowledged biases

I believe that the West, led by the United States and a Europe that must finally shoulder its fair share of the military burden, remains the only force capable of containing the axis formed by Russia, China, Iran and North Korea. This conviction does not stop me from recognizing the legitimate tensions created by the sometimes blunt methods of the Trump administration toward its own allies.

What I don't know yet

I cannot predict with certainty whether the 2027 target for Europe to fully assume conventional responsibility will actually be achievable, nor how large the American withdrawal resulting from the posture review announced by Secretary Hegseth will ultimately be.
