European allies question reliability of US-backed arms pipeline for Ukraine as Iran war strains US stocks

European allies are increasingly concerned about the viability of the PURL program for supplying US-made weapons to Ukraine.
Multiple reports say the war in Iran has depleted US stocks of precision weaponry and contributed to delays in American weapons sales.
Officials cited in the reports said the Trump administration has not diverted equipment already pledged to Ukraine since the US attack on Iran began.
European officials are worried that US weapons shortages, which are already affecting some of their own orders, could also delay deliveries intended for Ukraine.
PURL is a NATO-backed mechanism under which allied countries purchase US-made weapons for Ukraine rather than the United States transferring them directly.
The program is intended to help provide weapons that Ukraine particularly needs from the United States, including air-defense systems and Patriot-related munitions.
Some donor countries have begun questioning how transparently or effectively the Pentagon is spending funds allocated through the PURL mechanism.
What remains unresolved is whether additional contributions and US supply capacity will be enough to keep PURL functioning without further delays for Ukraine.

Both agree: PURL’s ability to keep supplying Ukraine with urgently needed US weapons is under strain, as broader American stock shortages and delays leave its future dependent on enough supply capacity and continued allied contributions.
They split on: Whether the story is about protecting Ukraine from delays in critical air-defense supplies, or about whether a Pentagon-run, donor-funded purchasing mechanism is transparent and disciplined enough to merit continued reliance.
