They refuted the White House's claim that "the U.S. weapons inventory is in crisis." Several people said that the weapons that Ukraine urgently needs are not urgently needed in other regions, so there is no need to stop delivering these weapons immediately. "We should indeed replenish our inventory, but the solution should be to speed up production, not to cut off supplies to Ukraine," said Richard Blumenthal, a Democratic senator from Connecticut. A European official said a NATO ally has urged the U.S. Department of Defense to reconsider the decision. John Herbst, director of the Atlantic Council's Eurasian Center, said the U.S. move contradicted a series of tough actions taken by Trump and his team last week. He was referring to the agreement among countries during the NATO summit to increase defense-related spending to 5% of GDP.
