The transatlantic arsenal that once flowed east has become a relay race — and Washington has dropped the baton.
1. The U.S. Retreat
The Kiel Institute’s Ukraine Support Tracker shows a 43 % drop in total military aid allocations to Ukraine between the first half of 2025 and the July-August period — the sharpest fall since the invasion began in 2022.
Beneath that headline number sits an even steeper U.S. retreat: direct American allocations now make up only a sliver of total Western support, down from roughly half of all aid during 2022-24.

2. From Arsenal to Arms Broker
The Trump-Hegseth Defense Department has largely stopped announcing new drawdowns or appropriations.
Instead, Washington’s role has shifted to a broker model — the NATO PURL Initiative — where European allies purchase U.S. weapons for transfer to Kyiv.
That scheme keeps American defense firms busy while letting the administration say it isn’t “funding another war.”
The trade-off: far less predictable deliveries, since European parliaments must foot the bill.
3. Europe Fills the Gap — Sort Of
According to Kiel’s August update:
- Europe’s monthly pledges rose to about €3.5 billion in early 2025.
- After July, that fell below €2 billion as stockpiles and political patience ran thin.
- The U.S. share shrank from roughly €1.8 billion per month in 2022-24 to well under €200 million in 2025.
The result is a coalition where Europe leads on paper but struggles to sustain the tempo once Washington steps back.
4. Strategic Consequences
- Operational strain: Ukraine’s planners can no longer count on steady U.S. shipments of ammo or spare parts.
- Diplomatic friction: Eastern allies—Poland, the Baltics—want the U.S. back in the driver’s seat; Western Europe prefers strategic “normalization.”
- Narrative spin: The White House calls this “burden sharing.” Critics call it abandonment by spreadsheet.
5. The Bigger Picture
Since January, the administration has approved no new large Congressional aid package, paused intelligence cooperation once, and trimmed Pentagon replenishment budgets.
What remains is momentum from Biden-era authorizations — a pipeline now sputtering as inventories run dry.
