The meeting between Donald Trump and Volodymyr Zelenskyy at the White House on 28 February was supposed to demonstrate a new economic partnership between the United States and Ukraine. Instead, it ended in an extraordinary public confrontation. Trump and Vice-President JD Vance accused Zelenskyy of insufficient gratitude for American support and argued that he was not demonstrating enough willingness to pursue diplomacy with Russia. Zelenskyy challenged the idea that Vladimir Putin could be trusted to respect another agreement, pointing towards Russia’s previous violations and the history of the conflict since 2014. The planned minerals agreement was not signed, the joint press conference was cancelled and Zelenskyy left the White House early. The spectacle was unprecedented, but the underlying conflict is more important than the personalities involved. Ukraine and the United States increasingly disagree not about whether peace is desirable, but about who should bear the risk if a peace agreement fails.
That distinction explains much of the confrontation. Trump’s administration wants the war ended quickly and increasingly views continued American support as a resource that should produce negotiations rather than sustain an open-ended military commitment. Zelenskyy’s government fears that a ceasefire without enforceable security guarantees could simply give Russia time to rebuild its forces and attack again. From Washington, accepting current battlefield realities may look like pragmatic bargaining. From Kyiv, accepting them without credible deterrence means placing the consequences of a failed agreement almost entirely on Ukrainians. The country advocating compromise and the country physically exposed to the consequences of compromise therefore evaluate the same agreement differently.
This is a classic problem of asymmetric alliance risk. The United States has provided Ukraine with enormous military, financial and intelligence support, giving Washington substantial leverage over Kyiv. But an American policymaker evaluating a settlement asks whether continuing the war is worth additional American resources and strategic risk. A Ukrainian policymaker asks whether the settlement leaves their country vulnerable to another invasion. Those are not identical objective functions. Alliances work when interests overlap sufficiently that the difference remains manageable. They become unstable when the stronger partner begins treating its preferred risk tolerance as something the weaker partner should automatically share.
Trump’s argument about gratitude therefore mixes two different concepts: assistance and ownership. The United States has every right to reconsider how much aid it provides because American resources ultimately come from American taxpayers and institutions. Ukraine simultaneously retains the right to determine what territorial or security arrangements it accepts because Ukrainians bear the direct consequences. Aid creates leverage. It does not create sovereignty over the recipient’s decisions.
The minerals agreement that was supposed to be signed illustrates the attempt to reconcile these interests through economics. Ukraine possesses deposits of critical minerals and other natural resources potentially valuable to American industry. Trump has argued that the United States should receive economic benefits in return for the enormous support already provided to Ukraine. Kyiv, meanwhile, hoped American investment would create a long-term US economic stake in Ukraine and thereby strengthen Washington’s commitment to the country’s security.
This is interdependence as implicit deterrence. If American companies invest billions in Ukrainian mining and infrastructure, another Russian invasion would threaten American assets as well as Ukrainian ones. Economic exposure can therefore create domestic constituencies inside the United States favouring continued Ukrainian security.
But commercial investment is not the same thing as a military guarantee.
A company losing a mine does not automatically cause the United States to enter a war.
This is why Zelenskyy has continued asking for explicit security commitments rather than assuming economic integration alone will deter Moscow.
The Budapest Memorandum of 1994 remains central to Ukrainian thinking. Ukraine surrendered the nuclear arsenal inherited after the Soviet collapse in exchange for assurances regarding its sovereignty and borders. Russia subsequently annexed Crimea in 2014 and launched the full-scale invasion in 2022. Ukrainians therefore possess unusually strong historical reasons to discount promises that lack enforcement mechanisms.
When Trump or Vance says diplomacy requires trust and compromise, Zelenskyy’s response is effectively:
what changes Russia’s incentive to violate the next agreement?
That is the correct strategic question.
The answer cannot simply be that Putin promises not to.
International agreements survive when compliance remains more valuable than violation.
That requires deterrence.
One mechanism would be NATO membership, but Trump’s administration has indicated that Ukrainian NATO membership is not a realistic outcome of a settlement. Another would be European or American troops stationed in Ukraine. Washington appears reluctant to provide that guarantee directly.
That leaves a third model: an armed-neutral Ukraine possessing enough military capability to make renewed invasion prohibitively expensive.
This could involve long-term weapons supplies, air defence, drones, domestic arms production, intelligence support and European financing without formal NATO membership.
The objective would not be defeating Russia permanently.
It would be changing the expected cost-benefit calculation of another attack.
This is deterrence by denial.
Europe therefore becomes increasingly important because Trump’s administration clearly wants Europeans to carry more of the burden. The Oval Office confrontation should remove any remaining ambiguity for European governments about the direction of American policy.
For decades, European states could assume that major continental security crises would ultimately involve overwhelming American leadership.
That assumption is becoming less reliable.
This weekend, British Prime Minister Keir Starmer is hosting European leaders in London to discuss Ukraine and European security after meeting both Trump and Zelenskyy separately. France and Britain have discussed possible security arrangements, including a European presence following a ceasefire.
This may become the beginning of a much larger shift.
European strategic autonomy is moving from intellectual debate towards fiscal necessity.
If Europe wants to determine the terms of peace on its own continent, it needs enough military capability to enforce those terms.
That requires money.
Europe collectively possesses an economy large enough to defend itself much more substantially. The constraint is political allocation. Defence competes against pensions, healthcare, climate investment and tax reductions.
For thirty years, the American security guarantee allowed Europe to spend more on those domestic priorities.
Trump is effectively attempting to change the price.
This is why his transactional approach can produce a paradoxical result.
Trump is less committed rhetorically to traditional Atlanticism.
His pressure may produce more European defence capacity than decades of pro-NATO American presidents achieved.
Distrust can create autonomy.
The question is whether the transition occurs quickly enough to preserve deterrence while Europe rearms.
Germany’s election last week makes this especially significant. Incoming chancellor Friedrich Merz has already argued that Europe needs greater independence from the United States. Germany possesses the economic scale to transform European defence if it changes fiscal priorities.
Poland is already spending heavily.
France possesses nuclear weapons.
Britain retains major military capabilities.
The resources exist.
Coordination is the harder problem.
European defence remains fragmented across national procurement systems, weapons platforms and political priorities. Twenty countries purchasing twenty variations of similar equipment can spend enormous sums without generating equivalent military capability.
This is the economies-of-scale problem of European defence.
Strategic autonomy therefore requires not only higher expenditure but integrated procurement, ammunition production, logistics and command structures.
Ukraine itself may become central to that process because after three years of war it possesses one of Europe’s most experienced militaries and an increasingly sophisticated drone and defence-industrial sector.
The country frequently described as dependent on European security could eventually become one of its principal military contributors.
This changes the economic calculation surrounding Ukrainian integration.
A secure Ukraine is not simply a recipient of Western protection.
It can become part of the system providing it.
The Trump-Zelenskyy confrontation also raises a question about diplomatic humiliation. Publicly pressuring a weaker ally may increase bargaining leverage, but it can make compromise politically harder for that ally. Zelenskyy cannot return to Kyiv after being publicly criticised and simply accept every American demand without appearing subordinate.
This is the audience-cost problem again.
Leaders negotiate internationally while simultaneously performing for domestic constituencies.
A private disagreement can produce compromise.
A televised confrontation creates reputational stakes.
Every concession afterwards looks more like capitulation.
This is why traditional diplomacy often occurs behind closed doors.
Secrecy is not always anti-democratic.
Sometimes it creates the political space required for bargaining.
The Oval Office exchange did the opposite.
It transformed differences over sequencing and guarantees into questions of respect and gratitude.
Those are harder to negotiate because they are not divisible assets.
Trump’s style intentionally rejects conventional diplomatic language. Supporters view this as useful because euphemism often hides genuine disagreements. The president states the leverage openly.
There is value in that.
But diplomacy also exists to reduce transaction costs between actors whose interests differ.
Courtesy is not merely decoration.
It allows governments to concede without appearing defeated.
A negotiating style that maximises visible dominance can therefore reduce the set of agreements politically available to the other side.
The same applies to Russia. If Trump wants Putin to accept concessions eventually, Moscow will also need a narrative allowing those concessions to appear consistent with Russian interests.
Peace deals need face-saving mechanisms for adversaries and allies alike.
This can be unpleasant because leaders responsible for war may receive diplomatic treatment critics believe they do not deserve.
Negotiation is not a reward.
It is a mechanism for changing behaviour.
The moral judgement of an actor and the strategic need to communicate with them are separate questions.
Trump is therefore correct that talking to Putin is not inherently appeasement.
The substance of the eventual agreement determines whether concessions become appeasement.
The danger is asymmetry.
If Washington places substantially greater pressure on Kyiv because Ukraine depends more heavily on American support while asking less of Russia because Moscow is harder to coerce, bargaining power can begin determining justice almost completely.
That may produce an agreement.
It can also create a moral hazard for aggression.
Potential aggressors observe that occupying enough territory creates leverage, while the victim eventually faces pressure from its own allies to compromise because continued defence becomes expensive.
This is why some enduring cost needs to remain attached to Russian aggression even under a negotiated settlement.
Sanctions.
Non-recognition of annexation.
Ukrainian rearmament.
European defence expansion.
Reconstruction obligations.
The exact combination can vary.
The principle matters.
A peace agreement should make renewed invasion less attractive than preserving peace.
Otherwise it is simply an armistice.
The Korean Peninsula demonstrates that an armistice can survive for decades when deterrence remains strong. North and South Korea never signed a comprehensive peace treaty after the Korean War. Fighting stopped because the military balance and American alliance made renewed war extraordinarily costly.
This is useful because it shows political reconciliation is not always necessary for durable negative peace.
Russia and Ukraine do not need to trust one another.
They need incentives not to restart the war.
Trust would help.
Deterrence is more reliable.
This is where the current American strategy remains incomplete. Trump clearly possesses a theory for reaching negotiations: use American leverage over Ukraine, communicate directly with Russia and reject objectives he considers unrealistic.
What remains less clear is the theory of enforcement afterwards.
Who responds if Russia violates the ceasefire?
What weapons does Ukraine continue receiving?
What sanctions return automatically?
What role do European forces play?
What happens to frozen Russian assets?
What happens if Ukraine violates the settlement?
These questions determine whether the deal survives.
A president can announce peace once.
Institutions need to maintain it every day afterwards.
The minerals agreement could still become part of that architecture, and both governments have reasons to repair the relationship after Friday’s confrontation. Ukraine needs American support. Trump wants an agreement demonstrating that American aid produces tangible returns.
Their interests therefore remain connected despite the argument.
This is why the meeting should not automatically be interpreted as the end of the US-Ukraine partnership.
Alliances can survive severe disagreements.
The more important question is whether the underlying bargain is changing permanently.
For three years, the American position was broadly:
help Ukraine resist Russia for as long as necessary.
Trump’s position is closer to:
use remaining American support to force a settlement and transfer more long-term responsibility to Europe.
That is a major strategic shift.
It may reduce American costs.
It may accelerate European rearmament.
It may shorten the war.
It could also produce an unstable settlement if security guarantees remain too weak.
Those outcomes need to be evaluated separately rather than treating the policy as automatically betrayal or automatically realism.
The objective should be measurable.
Fewer Ukrainians and Russians dying.
Ukraine remaining sovereign and economically viable.
Russia lacking incentives for another invasion.
Europe carrying a sustainable share of its own defence.
America reducing commitments without destroying alliance credibility elsewhere.
If a Trump-brokered settlement achieves those outcomes, the confrontational diplomacy will matter less historically than critics currently assume.
If the result is a ceasefire followed by another Russian attack after rearmament, the Oval Office confrontation will look like the moment Washington prioritised ending the current war over preventing the next one.
That distinction cannot be known this weekend.
What Friday did reveal is the distribution of power inside the alliance.
Ukraine possesses sovereignty.
America possesses leverage.
Europe possesses economic resources it has not yet converted fully into military power.
Russia possesses enough battlefield capacity that it cannot simply be dictated to.
Peace will require reconciling all four facts.
Public arguments can reveal them.
Only institutions and credible guarantees can turn them into a stable settlement.
The problem was never convincing Ukraine that war is costly.
Ukraine knows that more directly than anyone in Washington.
The problem is convincing Ukrainians that stopping the war will leave them safer than continuing to fight it.
Until the proposed agreement can answer that, pressure may produce signatures.
It will not necessarily produce peace.
