The Biden administration has given its Ukrainian counterparts another reason for not sending them much-wanted long-range missiles: The U.S. is concerned it wouldn’t have enough for itself.
In recent meetings at the Pentagon, U.S. officials told Kyiv’s representatives that it doesn’t have any Army Tactical Missile Systems to spare, according to four people with knowledge of the talks. Transferring ATACMS to the battlefield in eastern Europe would dwindle America’s stockpiles and harm the U.S. military’s readiness for a future fight, the people said.
