At the White House, Europe arrives beside Zelenskyy — and still cannot guarantee the outcome

The photograph from the White House was the point. Volodymyr Zelenskyy stood with Donald Trump while Europe's most senior leaders stood behind him.

The meeting on 18 August was arranged in a weekend after Trump's summit with Vladimir Putin in Alaska. It brought together the presidents or prime ministers of Ukraine, France, Finland, Italy, Germany and the United Kingdom, alongside the presidents of the European Commission and European Council and NATO's secretary general.

The leaders came with one shared demand: any settlement must include Ukraine and must be backed by security guarantees. They did not arrive with a settlement of the war.

Trump said the United States was willing to support European efforts to police a peace deal. He called Putin after the meeting and said arrangements for a possible Putin-Zelenskyy meeting had begun. No date, agenda or agreement followed in Washington, over time ahead.

The tone marked a change from Zelenskyy's difficult February visit to the White House. The Ukrainian president thanked Trump and described the encounter as constructive. European leaders treated the meeting as evidence that they could shape the diplomacy by appearing together.

The practical limits were clear. Russia was not in the room. The United States had not committed to a specific guarantee. European governments had not committed troops. Ukraine had not accepted territorial concessions.

The meeting therefore advanced the process without resolving its central risks. Europe demonstrated political support for Kyiv and dependence on an American decision-maker at the same time.

A summit assembled around an absence

The Washington meeting was not on the diplomatic calendar months in advance. It followed the 15 August Trump-Putin summit in Alaska, which produced no publicly announced ceasefire but created a new urgency for Ukraine's partners.

European leaders met in Brussels on 17 August to coordinate positions before travelling. Emmanuel Macron, Keir Starmer and Friedrich Merz co-chaired the Coalition of the Willing discussion with Zelenskyy. The group reaffirmed support for a just and lasting peace and said pressure on Russia should increase if no ceasefire was agreed.

The coalition's purpose is deliberately broad. It includes countries willing to plan support for Ukraine and a possible force after a ceasefire. Its membership is not identical to NATO or the EU, and participation in a future deployment would require national decisions.

António Costa, the European Council president, said the EU and United States should work together on security guarantees. The formulation was designed to keep Washington engaged while ensuring that Europe was not asked to accept a settlement made without it.

Those constraints shaped the delegation to the White House. Starmer could speak for Britain, Macron for France, Merz for Germany and Meloni for Italy. Von der Leyen could represent the Commission's role in sanctions and economic support. None could promise the EU's 27 governments a military commitment without further decisions.

The group was also chosen for political access to Trump. Some leaders have maintained close relations with him; others have argued that Europe needs greater strategic autonomy. The common denominator was not a shared view of the future. It was a shared concern that a US-Russia process might leave Ukraine with terms it could not defend.

The meeting's staging reduced that risk by putting European objections inside the room. It did not remove the asymmetry. Trump controls the US diplomatic channel, Putin controls Russia's military decisions and Zelenskyy represents the country that would bear the consequences of any agreement.

The White House statement presented the gathering as a return of American leadership. European accounts emphasised unity and support for Ukraine. Both descriptions can be accurate. The fact of a meeting does not settle who sets the agenda after it ends.

Security guarantees are a category, not a plan

The phrase “security guarantees” carried most of the diplomatic weight in Washington.

For Ukraine, a guarantee must deter Russia from attacking again and provide assistance if deterrence fails. For European governments, it must be politically and legally credible without automatically creating a war between NATO and Russia. For the United States, it must define a role that supports Europe without committing to an open-ended deployment.

Those requirements point in different directions. A promise of weapons and intelligence is easier to make than a promise to send troops. A multinational force can reassure Ukraine after a ceasefire but may not deter a Russian attack if Moscow doubts that the force would be reinforced. A treaty guarantee may be stronger legally and harder to secure politically.

Trump's willingness to support European efforts was therefore significant but incomplete. The White House did not announce the size, command or rules of any force. European leaders did not disclose a final list of contributors. Ukraine did not accept a settlement that would limit its sovereignty or armed forces.

The Coalition of the Willing had been working on planning since the spring. Britain and France had discussed an operational headquarters and possible reassurance force. The Washington meeting connected that planning to a potential US role, but the connection remained political rather than operational.

That distinction matters for the timeline. A force would need a mandate, logistics, air defence, rules of engagement and an answer to what happens if Russia refuses the ceasefire. Those decisions cannot be made by a photograph or a general assurance.

The economic side of a guarantee is equally important. Ukraine's defence industry, budget support and reconstruction financing determine whether the country can sustain its own security. European leaders have promised continued assistance, but annual budgets and parliamentary votes remain the mechanism.

The US role in European defence is also unsettled. Trump has demanded that Europe spend more and has sometimes questioned traditional alliances. His presence in the meeting reassured leaders that Washington was still engaged; his unpredictable negotiating style made the reassurance conditional.

European governments thus sought to turn American involvement into a shared process. If Trump supports a European plan, the plan gains weight. If he prefers a direct deal with Putin, the European presence can still limit the room for concessions, but it cannot veto them.

The term “guarantee” will remain contested until its instruments are specified. In August, Washington produced agreement on the need for one and no agreement on what it would contain.

Zelenskyy wins the room, not the war

The contrast with February was central to the coverage of the meeting.

In February, Zelenskyy's confrontation with Trump and Vice President JD Vance ended without the minerals agreement the administration had sought. In August, European leaders joined him and the public exchanges were respectful. Trump said the United States would consider supporting European efforts to secure a peace arrangement.

That change gave Kyiv diplomatic space. Zelenskyy could insist that Ukraine be involved in negotiations while accepting that the US president controlled the next move. He could welcome a possible leaders' meeting without committing to terms Russia had not accepted.

European leaders also benefited. Their presence showed that the war's outcome affects the continent and that European governments were prepared to assume more responsibility. Merz and Starmer could support the idea of a future force without announcing troops. Macron could press the case for European strategic capacity while keeping the US inside the discussion.

The unity had political limits. European governments differ over how much risk they will take, how to define a ceasefire and whether a force should deploy inside Ukraine or along a contact line. Some have more military capacity; others face stronger public opposition.

The same is true in Washington. Trump wanted a process that could produce a visible diplomatic breakthrough. European leaders wanted terms that would not reward aggression. Zelenskyy wanted guarantees strong enough to prevent a second invasion. The interests overlap only partially.

The phone call to Putin after the meeting illustrated the tension. Trump could move from a multilateral room to a bilateral channel within hours. Europe could offer advice and support but could not direct that call. The result was a proposed next step — a Putin-Zelenskyy meeting — without a commitment from Moscow.

That outcome is neither failure nor settlement. It is an opening, not a complete answer yet. It is a negotiating opening whose value depends on what happens next. If Russia refuses a meeting or uses it to delay, the coalition will need a strategy for pressure. If talks occur, Ukraine and Europe will need a common position on territory, sanctions and enforcement.

The August meeting also exposed the difference between symbolic and operational unity. European leaders were united enough to travel together. They were not yet united enough to specify a force or a guarantee. Turning the first into the second is the work of defence ministries and parliaments.

After Washington, the test moves to Europe

The European Council held a videoconference on 19 August to review the Washington discussions. Costa said European leaders remained united in support of a just peace and would work with the United States and Ukraine on the next steps.

That follow-up is as important as the White House meeting. European governments now have to decide what they are willing to contribute if negotiations advance. They must also prepare for the possibility that Russia declines and fighting continues.

The answer will involve more than foreign ministries. Defence budgets, sanctions enforcement, energy security and refugee policy all shape the credibility of a guarantee. A country cannot promise to police a ceasefire if it lacks transport, intelligence or air-defence capacity. It cannot sustain pressure on Russia if its energy and industrial policies are not resilient.

The EU has tools that NATO and the Coalition of the Willing do not. It can coordinate sanctions, finance reconstruction and align member states' economic measures. NATO can plan military defence. Britain can provide capabilities outside the EU's institutional chain. The challenge is to make those instruments reinforce one another.

The meeting also changes the political cost of exclusion. If any future US-Russia negotiation omits Ukraine or Europe, the Washington photograph will be cited as evidence that the omission contradicts the public position of the partners most affected. That is diplomatic leverage, though not a veto.

For Ukraine, the immediate priority remains its own armed forces. Security guarantees can supplement national defence but cannot replace it. European and US support will be judged by the weapons, training and money that arrive while talks continue.

For Russia, the presence of European leaders signals that a settlement cannot be defined only by the relationship between Moscow and Washington. Whether the Kremlin treats that as a constraint or simply waits for divisions will depend on the consistency of European policy.

The White House meeting was therefore a test of political choreography with strategic consequences. Europe succeeded in placing itself beside Ukraine and keeping the US engaged. It did not secure a guarantee, a ceasefire or a Russian commitment to meet.

Those absences are the next story. The value of the August summit will be determined by whether its carefully assembled unity produces decisions that can survive the pressures of negotiation and the possibility of renewed war. The coming weeks will show whether the proposed sequence — American pressure, a Russian response, a Ukrainian decision and European planning — becomes diplomacy or another pause in the fighting. Each actor can slow the sequence without formally rejecting it. That is why the language of the meeting matters. It created expectations, but no enforcement mechanism. Europe will have to keep its position coherent while negotiating with Washington and supporting Kyiv. The White House gathering made unity visible; the follow-up will determine whether it is useful. That follow-up requires a written plan, a funding source, a chain of command and a decision about what happens when Russia refuses the terms. It requires Ukraine to retain agency and Europe to accept responsibility for the risks it says it is prepared to manage. Without those elements, security guarantees remain a diplomatic phrase. With them, the August meeting could become the point at which Europe moved from appearing beside Ukraine to acting with it. The credibility of that move will be decided by implementation, not ceremony. It will be visible in the decisions taken when public attention has shifted elsewhere, when the promises face their first real test in Kyiv, Brussels and Washington.
