The White House, State Department, and Pentagon say they do not know what Israeli Prime Minister Benjamin Netanyahu was talking about when he said this week that Secretary of State Antony Blinken was working to remove “bottlenecks” holding up weapons shipments to Israel. But one U.S. official offered an explanation for the Israeli leader’s accusation.

The U.S. has been reviewing one shipment of 2,000-pound and 500-pound bombs since May. As Israel was preparing for a major offensive in Rafah, the Biden administration paused the shipment because, as President Biden put it in an interview last month, "Civilians have been killed in Gaza as a consequence of those bombs.

According to the U.S. official, Netanyahu’s remarks in the video are apparently based on IDF chief of staff Lt. Gen. Herzi Halevi’s belief that the U.S. is slow-rolling Israel on smaller-ticket items like aircraft spare parts. However, the official insists there’s been no such delay, except for the shipment of 2,000-pound bombs, which were about to leave an East Coast weapons depot by ship when the delivery was halted in early May. They were about to leave an East coast weapons depot by ship when the delivery was halted. Israel doesn’t need them for Gaza, but it would if the conflict in Lebanon escalates further.

John Kirby, the White House national security communications adviser, told reporters Thursday the administration didn’t know about Netanyahu’s video in advance and said it was “perplexing” and “disappointing.”

“There’s no other country that’s done more, or will continue to do more than the United States to help Israel defend itself,” Kirby said.
