COMMENTARY: Stringer and NATO "Cohesion" — The Honest Conversations of Ankara

COMMENTARY: Stringer and NATO "Cohesion" — The Honest Conversations of Ankara

Introduction: an air marshal who says openly what others only think

Stringer speaks to the AP — and the candor stands out

There are moments when a senior officer says something so direct that it stops you cold — not from shock, but from the sheer rarity of honesty in the glass palaces where the diplomacy of the Atlantic Alliance is manufactured. Air Marshal John Stringer, Deputy Supreme Allied Commander Europe, gave an interview to the Associated Press on June 26, 2026, less than two weeks before the crucial Ankara summit. And he said, plainly, that the summit needed to be a forum for "honest conversations" about cohesion, spending, and support for Ukraine.

Among diplomats, the word "honest" is an admission that less honest things have been said before. In the mouth of a British general at the top of NATO, it is a coded way of saying: we have a problem. Several, in fact. And Ankara is supposed to fix them.

The context: an alliance under tension since The Hague

The last major NATO summit was held in The Hague in June 2025 in an atmosphere of imminent catastrophe — predictions were rife about American withdrawal from the alliance. Mark Rutte, Secretary General, had ultimately managed to keep Donald Trump on board at the price of a collective commitment to raise defense spending to 5% of GDP by 2035. A result deemed "historic" — but whose implementation, in June 2026, remains highly uneven.

The Ankara summit, on July 7-8, 2026, must therefore be the summit of implementation. Rutte himself declared: "NATO 3.0 is really happening." Stringer adds the nuance: the credible roadmaps must actually be on the table.

The 5% target: promise or real commitment?

A figure that revolutionizes national budgets

The commitment of 5% of GDP for defense, decided at The Hague, with 3.5% for the military "core," is unprecedented in the Alliance's history. For most Western European members, this means doubling or even tripling current budgets. France, spending around 2% of GDP in 2024, would need to reach 3.5% "core" within ten years. Germany, still at 2.1% in 2025, would need to do the same. These figures imply major fiscal reforms and painful political choices.

Stringer is explicit in his interview: nations must present a "credible pathway" to 3.5% at Ankara. The United Kingdom, of which Stringer is a national, "is as bound to this objective as anyone else," he says — a formulation that acknowledges even London, which spends relatively more than its neighbors, must do more.

Who is actually ready? The map of real spending

In June 2026, only a handful of members are approaching the required targets. Poland spends over 4% of GDP — it is ahead of the curve. The Baltic states have each crossed the 3% threshold and continue rising. Greece, pushed by its tensions with Turkey, maintains elevated levels. But Italy, at 1.54% in 2024 — then 2% in 2025 through accounting reclassifications — remains far below. Belgium, Spain, and Portugal find themselves in analogous situations.

The real test of Ankara is whether these laggards will present costed roadmaps with binding legislative commitments — or whether the summit will once again settle for politely worded declarations of intent.

Hegseth and the conditional threat: America's coercion of the alliance

"Free riding": the accusation that will not let go

On June 18, 2026, during a NATO ministerial meeting in Brussels, US Secretary of Defense Pete Hegseth accused alliance members of "free riding" — of enjoying American protection without paying for it. This is not the first time this charge has been leveled from Washington; but its growing intensity, combined with the context of a review of US military posture in Europe, gives it particular resonance.

Hegseth also announced a six-month review of US forces' posture in Europe, explicitly tying the continuation of American commitments to allied progress on spending. The cancellation of 4,000 planned US troops in Poland in mid-May — without official explanation — had already sent a worrying signal.

American reliability: the real taboo subject

The Guardian's article of June 27, 2026 — "All quiet on the eastern flank? NATO leaders fear they can no longer rely on US help if Russia attacks" — names what is usually said only in private: European leaders doubt American reliability in the event of a Russian attack on the Eastern flank. This is not a question of military capability — the United States remains the world's preeminent military power — it is a question of political will.

If Trump, in some form, decided that defending the Baltic states was not politically worth it, Article 5 would become a dead letter. This is the hypothesis that European military planners must now incorporate — and that the Ankara summit must address without euphemism.

Stringer and the technical vision: Bayraktar drones as a model

Open architecture against defense monopolies

Beyond the grand political questions, Stringer laid out before Anadolu Agency a technical vision for tomorrow's NATO: move toward open, interoperable software architectures, break with the proprietary systems controlled by a handful of major contractors, and enable rapid integration of new technologies. He cited Turkish Bayraktar drones as an example of this model.

This vision is consistent with the lessons of the war in Ukraine, where rapid technological adaptability — particularly in the drone domain — has proved decisive. The closed, expensive military systems of conventional armies struggle to adapt at the speed of modern conflict.

Turkey at the center of the game

The choice of Ankara as summit host is not incidental. Turkey is a unique case within NATO: a founding member, the alliance's second-largest army, but also a country maintaining commercial and diplomatic relations with Russia despite the war. Erdoğan plays a mediating role in Ukrainian-Russian negotiations, manages the Bosphorus and Dardanelles straits with calculated skill, and exploits his geostrategic importance to maintain an autonomy few other allies can afford.

Stringer underscores that Ankara is "of considerable importance to the Alliance" — a diplomatic understatement acknowledging that NATO needs Turkey as much as Turkey needs NATO. This reality complicates any desire to pressure Ankara.

The Eastern flank: the fear that dare not speak its name

Finland, Sweden and the new Nordic perimeter

The accession of Finland (2023) and Sweden (2024) to NATO has radically changed the Alliance's northern geography. Scandinavia and the Baltic states now form a continuous front from the Barents Sea to the Gulf of Finland. Exercises like BALTOPS 2026 — twenty ships, six thousand personnel from fifteen nations — signal an enhanced military presence in the Baltic Sea.

In Finland, a NATO battle group under Swedish command, based in Boden, was officially inaugurated in June 2026. This is the concrete realization of forward presence on the Northern flank — one of the promises made at the time of accession.

Germany and the permanent brigade in Lithuania

Germany committed to deploying a permanent brigade in Lithuania — around 5,000 troops stationed on a durable basis rather than in rotation. This is a major doctrinal shift: the language is no longer "enhanced forward presence" but permanent territorial commitment. For Lithuania, which shares a border with Belarus and the Kaliningrad enclave, this is a concrete guarantee.

But even this brigade, expected for months, is slow to reach full operational status — logistical problems, infrastructure challenges on the ground, and German budgetary disputes are slowing its build-up. This is a typical example of the gap between political announcement and military reality.

The "tens of billions" in contracts: the industrial dimension of the summit

Rutte and the massive military procurement

Mark Rutte announced that Ankara would see the signing of defense contracts representing "tens of billions of dollars." According to Anadolu Agency (June 25, 2026), these cover group orders in the domains of munitions, air defense systems, armored vehicles, and command-and-control systems. This is the concrete realization of what Stringer called the "quadrupled munitions production" — such as 155mm shells that European countries are accelerating the production of.

This industrial dimension is vital: NATO cannot project the required spending levels without a defense industrial base capable of absorbing them. Europe has underinvested in its production capabilities for thirty years, and the war in Ukraine has brutally exposed the limits of that neglect.

The defense industry: acceleration underway

Companies like Rheinmetall, BAE Systems, Leonardo, and KNDS have all announced massive capacity expansions since 2022. Shell plants in Germany, the UK, Poland, and Estonia. Tank production lines reactivated or created from scratch. But the industrial ramp-up takes time — and the Ukrainian front consumes munitions at a rate that even Ankara's ambitions will not immediately satisfy.

The production rate of 155mm shells in Europe has tripled in two years, according to figures circulating in NATO circles. This is real progress — insufficient, but real. Stringer is right to cite it as a concrete example of what nations are doing.

NATO 3.0: marketing brand or reality?

Rutte's rhetoric against structural challenges

Secretary General Mark Rutte has adopted the concept of "NATO 3.0" to describe the Alliance after The Hague: more spending, more integrated, with strengthened conventional capabilities. The formula is effective — it gives the impression of deep transformation. But the structural challenges remain: consensus rule, national sovereignty over engagement decisions, deep divergences on the Russian threat.

An analyst I respect, Simon Gros, described on June 21, 2026 what he calls the transatlantic "rebalancing" of NATO — a process in which Europe takes on a growing share of its own defense, not from ideological choice but from strategic necessity. This may be the most honest definition of NATO 3.0: an alliance adapting to American unpredictability by making itself less dependent on it.

Ukraine at the heart of the summit

The Ukrainian question will, as always, be central at Ankara. Zelensky declared at the end of June that the window for peace negotiations remained open until winter 2026, but that Russia had to make the first move. In that context, NATO's support — in weapons, financing, political signals — is vital to maintaining Ukraine's negotiating position.

Stringer was clear: the summit must "reaffirm support for Ukraine." This is not guaranteed. Some delegations, anxious not to further provoke Russia or influenced by Trumpian rhetoric, may seek to dilute this signal. Vigilance is essential.

Lessons from Ukraine: reconfiguring combat doctrine

Drones, counter-battery and electronic warfare

What Stringer has absorbed from the war in Ukraine — and what NATO planners are progressively integrating — is that the contemporary battlefield is radically different from what the alliance had prepared for during the Cold War. Drones of all sizes, intensive electronic warfare, long-range precision strikes, real-time information warfare — all of this is reshaping combat doctrines.

NATO armies have Leopard and Abrams tanks, F-35 aircraft, Patriot systems — an impressive arsenal. But they still lack the mass of drones, the electronic warfare capabilities, and the operational flexibility that the war in Ukraine has revealed as decisive. Stringer calls for urgent transformation: fewer closed and costly systems, more open and rapid integration.

Artillery production: test of industrial responsiveness

Stringer's mention of the "quadrupling" of 155mm shell production is significant. At the start of 2023, Europe was producing around 300,000 155mm shells per year. The stated goal is now 2 million per year by 2025-2026. Actual figures remain below target, but the progress is real. This is an unprecedented industrial transformation since the Cold War.

This artillery production is symptomatic of a broader transformation: Europe is relearning to think in terms of attrition warfare, massive munitions consumption, strategic stockpiles — realities it had erased from its doctrinal memory during thirty years of the peace dividend.

Cohesion and unity: the words that mask the cracks

Cohesion as diplomatic performance

Stringer said it explicitly: summits are "highly political events and a demonstration of an organization's unity." This is a remarkably honest definition of what these grand occasions really are: less places of decision than stagings of solidarity. Real decisions happen in corridors, working groups, and the bilateral negotiations that precede the summit.

At Ankara, the stakes of performance are particularly high. Eastern allies want to see firm commitments on spending and Ukraine. Washington wants to see that Europe is finally paying its share. Ankara wants to be treated as a central partner, not a difficult periphery. And Kyiv, which is not part of the alliance, watches and hopes for signals of sustained support.

The honest conversations Stringer is calling for

What would these "honest conversations" Stringer invokes look like? Here is what I imagine: a frank discussion about the fact that some allies will not meet their spending commitments. A recognition that American reliability is conditional and that Europe must prepare for that. A realistic assessment of European forces' actual capabilities, beyond announcements. And a serious conversation about what defending the Eastern flank actually means if Russia crosses a NATO border.

These conversations, if they happen, will not appear in press releases. They will take place in closed rooms, between heads of state and military chiefs. And that is perhaps the real substance of Ankara: not the final declaration, but what is said when the cameras are off.

NATO and Ukraine: the membership debate returns

Ukrainian membership: still on the table

Ukraine's relationship with NATO remains one of the most delicate questions in current diplomacy. Zelensky has called for solid security guarantees — which include, in his view, a NATO "invitation" as a long-term commitment. Eastern allies support this request; the United States and Germany remain more reluctant, fearing escalation with a Russia that regards any NATO expansion as a red line.

At Ankara, the issue will likely be addressed in terms of aid to Ukraine — material, financial, intelligence — rather than formal membership. This is the compromise position that allows everyone to be half-satisfied: enough support to sustain Ukrainian resistance, not enough commitment to trigger direct escalation.

The "tens of billions" for Ukraine

Rutte referred to massive defense contracts at Ankara — and part of that money is indirectly earmarked to strengthen the capabilities that the West transfers to Ukraine. Additional Patriots, HIMARS, guided precision munitions — this flow of weapons conditions Kyiv's ability to resist and to negotiate from a position of strength.

The paradox is that the more Ukraine resists with Western weapons, the greater the pressure on Russia — and the more favorable the conditions of a potential peace agreement become for Kyiv. Military solidarity is therefore, simultaneously, a peace policy.

The United Kingdom's role: a loyalty that comes at a price

London, NATO's quiet pillar

The United Kingdom is, along with the United States, one of the few NATO members that durably exceeds spending objectives. Stringer, as a British officer at the very top of the Alliance, embodies this tradition: a country that, despite Brexit and its turbulence, has maintained its Atlantic commitment consistently. London was among the first to deliver modern weapons to Ukraine — Storm Shadow missiles, Challenger 2 tanks, military training.

But even the United Kingdom must now show its own roadmap toward 3.5% of GDP. The British defense budget was around 2.3% in 2025, with a target of 2.5% by 2027. Reaching 3.5% by 2035 will require difficult budgetary choices for a government already under fiscal pressure.

British exemplarity as a lever

In NATO's corridors, a country that meets its commitments has moral authority to demand the same of others. This is one of the United Kingdom's quiet assets — and of Stringer's position. When he says the UK is "equally bound" to the targets, he is not deflecting. He is signaling that the requirement applies to all, including the good pupils.

This is a form of leadership-by-example that contrasts with Trumpian rhetoric of "free riding," grounded in coercion. Both can work — but it is the British approach that builds a durable alliance, not cooperation under duress.

The civilian stakes: what does NATO 3.0 mean for European citizens?

Military budgets biting into social budgets

Raising defense spending to 3.5% and then 5% of GDP implies societal choices. In Europe, where welfare states are robust and citizens are attached to public services, these trade-offs will be painful. Germany has already debated a VAT increase to fund defense. France is considering an expanded voluntary military service scheme. These measures are necessary — but they require political explanations that few governments have yet provided.

The risk is that citizen reluctance — visible in Italy (57% opposed), Spain, Germany — feeds populist movements that will tomorrow campaign for NATO withdrawal or defense budget cuts. The paradox: to sustain the alliance long-term, leaders must convince their populations of present-day sacrifices.

Strategic communication as a political challenge

European governments must do pedagogical work they have long neglected: explaining why defense is expensive and what its absence would cost even more. The Ukrainian example — a country whose capital was bombed, whose cities were razed, whose economy was devastated — is the most powerful argument possible. But it takes political courage to deploy it without hesitation.

Stringer, by participating in public interviews and using accessible language, is part of this effort. Officers who explain, who decode, who put numbers on abstract stakes — they are also actors in collective security.

The question of command: who makes decisions at NATO?

The integrated command structure and its tensions

Behind the summit's cohesion rhetoric lies a complex organizational reality: NATO has an integrated command structure whose SACEUR (Supreme Allied Commander Europe) — a post traditionally held by an American general — sits at the operational apex. Stringer, as DSACEUR, is the number two. This structure guarantees interoperability, but places ultimate command in American hands — raising existential questions at a time when American reliability is in doubt.

Discussions about a "European fallback command structure" — a capacity to operate without the United States if necessary — are progressing slowly. Exercises like STEADFAST JUPITER have tested these scenarios. But moving from exercise to actual operational doctrine requires political decisions that few capitals are willing to make publicly, for fear of sending a signal of Atlantic fracture.

European officers and professionalization

The presence of John Stringer — a post-Brexit British air marshal — at the top of the NATO hierarchy sends a quiet but important signal: the United Kingdom remains a pillar of the Alliance despite its departure from the EU. More broadly, the professionalization of European armed forces since 2022 has produced a generation of senior officers who have absorbed the lessons of the war in Ukraine. This generational transformation in European armies is one of the least covered — but most important — aspects of the Alliance's transformation.

The officers commanding NATO forces today have observed in real time the failures and innovations of the war in Ukraine. They have reformulated training doctrines, revised logistical structures, and pushed for different equipment acquisitions than those of the Cold War. This is a silent revolution — and it is perhaps the most durable transformation that Ankara can consolidate.

Ankara and the future of European security architecture

The NATO-EU link: coordination progressing

One of the most significant developments since 2022 is the strengthening of coordination between NATO and the European Union. The two organizations now share threat assessments, coordinate exercises, and have regular consultation mechanisms at the military level. The EU's Strategic Compass, adopted in March 2022, set ambitious objectives — notably the creation of a Rapid Deployment Force of 5,000 troops. These objectives are progressing, if slowly.

The paradox is that the 21 members common to both NATO and the EU now benefit from a dual security architecture — which creates coordination opportunities but also risks of duplication. The question of who leads — the Alliance or the Union — is unresolved. Stringer prefers to see it as complementary. Euroskeptics prefer NATO. European federalists prefer the EU. Ankara will have to navigate between these visions.

What Ankara can concretely achieve

Beyond rhetoric, what Ankara can concretely achieve comes down to a few measurable elements: quantified and binding spending commitments, defense contracts signed for specific amounts, reaffirmed support for Ukraine with concrete deliverables, and — perhaps — initial serious discussions about mechanisms to verify commitments made. If these four elements feature in Ankara's final declaration, the summit will have produced something real.

If, on the other hand, Ankara produces general declarations about "unwavering solidarity" and commitments to "continue discussions" — that is the sign of a failed summit. The difference between a historic summit and a façade summit is precisely the measurability of commitments made. Stringer said it with his characteristic frankness: he wants "credible pathways." Pathways, not statements of intent.

Conclusion: Ankara — a summit for history or for the showcase?

Stringer's expectations: a truth test

Air Marshal John Stringer has set out the test of Ankara with unusual clarity: cohesion, credible pathways toward spending targets, reaffirmed support for Ukraine, and honest conversations about what is not working. These are the criteria of a successful summit — not a summit that produces a nice communiqué, but one that actually changes something.

If NATO's 32 members leave Ankara with quantified and verifiable commitments, if the "tens of billions" in defense contracts are signed, if support for Ukraine is maintained without ambiguity — then NATO 3.0 will cease to be a slogan and become a reality. That would be a genuinely historic summit.

The alternative: one more summit

The alternative is familiar: a well-worded final declaration, variable-geometry commitments, a press conference where each party hears what they want, and a return to normal in the weeks that follow. The world has seen dozens of summits of this type. The difference today is that the war in Ukraine no longer permits the luxury of business as usual. Putin is watching. Xi Jinping is watching. Kim Jong-un is watching. What they see at Ankara will say a great deal about the West's real health.

Columnist's transparency note

My positioning and my biases

I am pro-NATO and pro-Ukraine. I consider the Atlantic Alliance, despite its flaws, the best guarantor of collective security in Europe. I am critical of positions that, through electoral calculation or excessive caution, weaken alliance cohesion. My treatment of Hegseth's rhetoric is harsher than my treatment of Stringer's — because I believe that coercion is a poorer foundation for an alliance than voluntary solidarity.

What I do not know

I do not have access to NATO leaders' private conversations. I do not know whether the spending commitments made at Ankara will be honored. I base my analysis on public statements, dated press articles, and analyses available as of June 27, 2026. The military spending figures I cite come from official estimates that may be revised. I do not pretend to know what will happen at Ankara — I analyze what appears to be taking shape.
