Military chiefs from the United States and a clutch of key European allies have now finished their first round of planning for Ukraine’s future security.
The files will soon be placed on the desks of their respective national security advisers, a bureaucratic handover that belies the gravity of the choices contained within them. For beneath the acronyms and briefing papers lies one of the most consequential strategic debates in decades: how, and by whom, Ukraine will be defended when the guns eventually fall silent.
The talks in Washington this week brought together senior officers from the United States, Britain, France, Germany, Italy, Finland and Ukraine. That list, though narrower than NATO as a whole, reflects the nations most directly engaged in Ukraine’s defence since Russia launched its full-scale invasion. It also reflects a blunt reality: post-war Ukraine will only be secure if these capitals, led in practice by Washington, are prepared to back up their promises with soldiers, aircraft and hardware.
Yet even at this early stage, fissures in approach are obvious. Some European leaders, notably Emmanuel Macron and Britain’s Keir Starmer, have made clear they would consider committing troops on the ground as part of a “coalition of the willing.” Germany’s Chancellor, Friedrich Merz, has hinted at openness, though Berlin remains scarred by its long reluctance to provide military aid.
The Americans, by contrast, are far more cautious. President Donald Trump has explicitly ruled out U.S. boots on the ground. But as so often with Mr Trump, his words left just enough ambiguity to keep allies guessing: air power, missile defence and a U.S.-led command structure are all still being discussed.
Trump’s pressure for a swift deal
The president has made no secret of his desire to bring Europe’s bloodiest war since 1945 to an end with maximum speed. The language of “peace through deal-making” is vintage Trump, who last week hosted Vladimir Putin in Alaska in a display of diplomatic theatre that alarmed Kyiv and reassured Moscow. For Ukrainian officials, his pledge that the United States would help provide “security guarantees” was encouraging, but it also came freighted with unease. Might those guarantees come only at the price of concessions on territory? Would Washington, under his watch, ultimately lean on Kyiv to accept something less than the liberation of its occupied regions?
Such questions explain why the Washington military conclave was so fraught. The chiefs of staff were tasked with drawing up not just a menu of options, but a political fig leaf: something that could be presented as robust enough to deter further Russian aggression while avoiding outright NATO membership, which Moscow has repeatedly declared a red line.
What would a guarantee look like?
Among the scenarios reportedly tabled was one in which European forces, rather than Americans, would deploy to Ukraine in the event of a post-conflict settlement. In this arrangement, U.S. officers would retain command and control, giving the operation the credibility of American oversight without requiring U.S. ground deployments. It is a halfway house solution—neither a full NATO umbrella nor a token monitoring mission—that reflects Europe’s nervousness about standing alone and America’s reluctance to shoulder all the burden.
Other options revolve around air defence. American F-35s, operating either from Poland and Romania or directly over Ukrainian airspace, could enforce a de facto no-fly zone. Additional U.S.-supplied Patriot and Aegis systems could create a defensive shield around major Ukrainian cities. These ideas, while technically feasible, would still amount to a major escalation in Western involvement, one that Russia would surely test.
The Kremlin has already fired warning shots. Moscow’s foreign ministry last week dismissed outright the notion of NATO troops on Ukrainian soil, declaring that such a move would amount to direct confrontation. Russia’s forces, meanwhile, have shown no let-up. Even as the Washington meetings were concluding, Russian missiles struck a gas compressor station in eastern Ukraine, a critical node for winter heating supplies.
Europe’s illusions
The bluntest assessment of what would be required came not from politicians but from within the German armed forces themselves. The head of Germany’s soldiers’ union cautioned that any “peace force” would mean tens of thousands of troops committed for the long haul. It was a rare injection of military realism into what has otherwise been an exercise in political hedging.
Europe’s political class has often spoken as if “security guarantees” can be conjured by communiqué. The reality is starker. A guarantee only carries weight if backed by credible force—and force requires men, money and public support. France and Britain, both nuclear powers, could provide frameworks for deterrence. Germany, with its industrial base, could supply equipment and logistics. But the elephant in the room remains the United States. Without American command structures, surveillance assets and above all political resolve, any European deployment would risk looking hollow.
The risk of another false promise
For Ukraine, the parallels with the 1994 Budapest Memorandum are inescapable. Then, Kyiv surrendered its nuclear arsenal in exchange for “assurances” from Russia, the United States and Britain that its borders would be respected. Two decades later, those assurances proved worthless. Today, Ukrainians are rightly asking whether another set of promises—however finely worded—will be any stronger.
That, ultimately, is the test for Western capitals. If the eventual deal is perceived in Kyiv as another paper shield, it will breed not peace but resentment. A generation of Ukrainians who have sacrificed lives and livelihoods will feel betrayed. And if Moscow reads the guarantees as weak or conditional, it will bide its time and regroup for another assault.
Trump’s gamble
Mr Trump’s instincts push him toward a “deal first, details later” approach. That may satisfy his desire to be seen as the man who ended Europe’s bloodshed, but it risks entrenching instability. His openness to providing air power while avoiding ground commitments is consistent with his broader America First philosophy: leverage U.S. technological superiority, but let others do the heavy lifting on the ground.
European leaders, meanwhile, face a test of their own credibility. Mr Macron and Mr Starmer may talk about deployments, but both know that sustaining large-scale forces abroad would be politically unpopular at home. Germany’s Merz faces even greater constraints: a public wary of militarisation and a Bundeswehr still underfunded despite promises of reform.
The road ahead
The military options now being placed before national security advisers are only the start of a long process. They will be dissected, reshaped and, in some cases, quietly shelved. But the fact that such discussions are now on paper marks an important shift. It is tacit recognition that Ukraine’s security cannot be left to vague pledges. It requires planning, resources and clarity about who will bear the risks.
For now, Russia will watch with interest as the West debates. Moscow understands better than most that the appearance of disunity can be as valuable as a battlefield victory. The longer Washington and Europe dither, the more room the Kremlin has to sow division.
The coming months will test whether the Western alliance can move beyond words to something approaching strategy. For Ukraine, whose survival hangs on these decisions, the difference could scarcely be more stark: between a future of tentative peace underpinned by credible deterrence, and one of uncertainty where today’s war becomes tomorrow’s frozen conflict.
