The Transatlantic Split

$750 million paid in by European NATO states, earmarked for Ukraine — now in American stockpiles. This is not a slip. It is the exposure of a structure that was always there.

I. What Happened

In July 2025, NATO created the PURL programme — Prioritised Ukraine Requirements List. The mechanism was simple: European partner countries pay, America delivers weapons to Ukraine. An elegant solution to the political problem that the US Congress was no longer willing to approve direct Ukraine aid. Europe picks up the bill, America delivers the goods.

On 23 March 2026, the Pentagon notifies Congress: the $750 million from the PURL programme will no longer be used for Ukraine. It will be used to replenish American munitions stockpiles depleted in the Iran war. Patriot and THAAD interceptor missiles paid for by Europeans go into American arsenals.

Asked whether this was accurate, Trump confirmed: “We do that all the time. We have tremendous amounts of ammunition, we have them in other countries — and we take, sometimes we take from one and we use for another.”

This is not the publication of a secret. It is the publication of the rule.

II. What It Means

European governments financed a programme in which they purchased American weapons for a specific purpose. That purpose is now unilaterally changed. The money is gone, the weapons are elsewhere, and Ukraine — which needs those interceptors against Russian ballistic missiles — faces an air defence gap.

The legal framework of the PURL programme apparently permits this reassignment. That is no accident. Whoever writes the contracts writes the exceptions. America wrote the contracts.

Zelensky responded immediately, calling on Europe to build its own air defence capacities: “We cannot rely on other partners’ industries.” That is the soberest sentence that can be said in this context. It comes from someone experiencing the consequences of this structure firsthand.

III. Trump Is Not the Cause

The European response follows the familiar pattern: outrage at Trump, appeals to “the values of the partnership”, Macron’s warning that the Iran war must not divert attention from Ukraine. All of this is understandable and inconsequential.

Because Trump is not the cause of the problem. He is its visibility. The structure he exposes exists independently of his person: America is a world power with global interests. Europe is a subcontinent with regional interests. When these interests collide, the world power decides. It was the same under Obama, under Bush, under Clinton. Only the packaging was more polite.

What Trump introduces is not a new policy. He introduces a new honesty about an old policy. “We do that all the time” — we always do this. The word “all the time” is the decisive one. Not “this time”, not “exceptionally”, not “because of the particular circumstances of the Iran war”.

Always.

IV. The New Doctrine

What is emerging now is not an anomaly that will disappear when Trump is no longer in office. It is the doctrine of a post-hegemonic America that distributes its resources according to American priorities — and expects its partners to pay for it.

The logic is simple and will be adopted by every future American president regardless of party: America is fighting a war in the Middle East that is emptying its munitions stockpiles. Europe has put money into a weapons programme. The weapons are needed. So they are taken. The next president may not say it quite so openly — but will do exactly the same.

The PURL programme was Europe’s attempt to use American delivery capacities without having to presuppose American willingness. It was a construction that works as long as America has no need of its own. As soon as that need arises, Europe is secondary. That is not a decision — that is arithmetic.

V. The German Example

At the NATO summit on 10 July 2024, Germany and the United States solemnly agreed: from 2026, Tomahawk cruise missiles, SM-6 rockets and hypersonic weapons would be stationed on German soil. Chancellor Scholz praised the agreement as a historic milestone for European security — the first stationing of American medium-range weapons in Germany since the end of the Cold War. For the first time since 1991, systems capable of reaching Moscow would again stand in Germany.

The German government has since deleted the joint declaration from its website. The reason is not hard to guess: Tomahawks and SM-6 are exactly the weapons systems America is currently consuming in the Iran war — and whose resupply is now to be financed from European PURL funds. The weapons intended for deterring Russia in Germany are in the Persian Gulf. And the European money intended for Ukraine is replenishing the stockpiles from which Germany was supposed to receive its Tomahawks.

This is not a domino effect. This is the structure that was always there: an American president decides where American weapons are needed. Europe pays. And when priorities shift, everything else shifts with them.

VI. The Illusion of Good Behaviour

European governments respond to this realisation with a strategy that has never worked historically: good behaviour. Pay more into NATO. Buy more weapons — American ones, naturally. Show more solidarity. Criticise less. Hope that America honours this and that the transatlantic partnership remains salvageable — including the nuclear umbrella that has been the foundation of European security policy since 1949.

The nuclear umbrella exists as a political gesture. As a military reality, it is tied to a condition that no one states aloud: that an American president is prepared to risk New York for Frankfurt. That readiness was always an assumption, never a guarantee. Trump has explicitly called it into question. But his predecessors never put it in writing either.

The European illusion runs: if we pay enough, deliver enough, stay quiet enough when it gets uncomfortable — then America will stay. That is the wrong question. America stays as long as it serves America. Not longer. Not shorter. That is not hostility. That is great-power logic.

Good behaviour is not a strategy against great-power logic. It is surrender to it — with a polite face.

VII. What Remains

What remains substantively of the transatlantic partnership is this: Europe may buy American weapons, cite American security guarantees, and consume American popular culture. In return, America expects Europe to finance its wars — including those for which Europe was not asked — and to be treated as secondary when conflicts arise.

That is not an accusation. It is a description. World powers have interests, not friendships. Everyone knows this. The question is why Europe pretended for so long that it was otherwise.

The answer is uncomfortable: because the illusion of partnership was cheaper than the reality of independence. Having one’s own air defences, one’s own munitions production, one’s own strategic decision-making capacity costs money. The transatlantic partnership was — among other things — an instrument for not having to pay those costs.

Now the bill is being presented. Not by Trump. By reality.

“We cannot rely on other partners’ industries.”
