The Biden administration has reacted furiously to criticisms by Benjamin Netanyahu that the US is holding back weapons and ammunition from Israel in its war in Gaza, reportedly cancelling a high-level meeting with Israeli officials on Iran in retaliation. Netanyahu made the claims of a supposedly deliberate weapons delay in a video posted on X in which he implied that Israel’s ability to prevail in the nine-month war with Hamas was being hampered as a result. Speaking to the camera in English, Netanyahu said he had expressed gratitude in a recent meeting with Antony Blinken, the US secretary of state, for American support since last October’s attack on Israel by Hamas, which killed about 1,200 and saw another 250 taken hostage. “But I also said something else,” he said. “I said it’s inconceivable that in the past few months the administration has been withholding weapons and ammunitions to Israel – Israel, America’s closest ally, fighting for its life, fighting against Iran and our other common enemies.” Invoking Winston Churchill, Netanyahu continued: “During world war two, Churchill told the United States, ‘Give us the tools, we’ll do the job.’ And I say, give us the tools, and we’ll finish the job a lot faster.” The broadside appeared to blindside US officials. White House press secretary Karine Jean-Pierre told reporters: “We genuinely don’t know what he is talking about.” At a later news conference, Blinken said that the only delayed weapons were 2,000lb bombs that Joe Biden had ordered to put under review because of concerns over an Israeli plan for an incursion into Rafah in southern Gaza, where up to 1 million people are sheltering. “That remains under review. But everything else is moving as it normally would,” said Blinken. The Biden administration finally won congressional approval for a $14bn military aid package for Israel in April after it was held up for months by the House of Representatives. A separate $15bn sale of US F15 aircraft is also set to move forward. Biden has pressed forward with aid despite opposition from within his own Democratic party, where progressives have accused Israel of committing genocide in a war that has now killed more than 37,000 Palestinians. Senior administration officials were said to be angry behind the scenes. Axios, citing two unnamed sources, reported that a bilateral meeting scheduled for 20 June had been called off to send Netanyahu a signal. The report said the US envoy to Israel, Amos Hochstein, had delivered the message to the prime minister personally, telling him that his accusation was “inaccurate and out of line”. “This decision makes it clear that there are consequences for pulling such stunts,” Axios quoted one American official as saying. A spokesperson for the White House national security council did not confirm the cancellation but amplified the perplexity over Netanyahu’s video. “We have been working to find a time to schedule the next SDG [sustainable development goals] that accounts for the travel and availability of principals, but have not yet fully finalized the details, so nothing has been cancelled,” the spokesperson, Eduardo Maia Silva, said in an email. “As we said in the briefing yesterday, we have no idea what the prime minister is talking about, but that’s not a reason for rescheduling a meeting.” Netanyahu is scheduled to visit Washington in late July to address a joint session of Congress, in response to an invitation by the House speaker, Mike Johnson, a close ally of Donald Trump, the presumptive Republican presidential nominee.
