The U.S. Is Burning Through Weapons in Iran. Russia and China Are Taking Note.

After attacking Iran alongside Israel on Feb. 28, Mr. Trump repeatedly promised victory within weeks. But it also shows how the president’s decision to attack Iran has left the United States and its allies more vulnerable to other threats. Mr. Trump regularly insists that Mr. Biden’s support for Ukraine is to blame for any shortfalls in U.S. weapons stocks. Long-range missiles would be critical in a war against China or Russia, countries with far more advanced air defenses than Iran. In Europe, U.S. allies are already looking to increase weapons purchases from other countries, given the production backlog in the United States.
