Let's get this timeline - Biden says something about stopping arms to Israel and almost immediately these documents are leaked, a leak that appears to embarrass the USA?
How does that stack up against making a full false website to support an operation that involved selling booby-trapped pagers and walkie-talkies into a very nervous supply chain via someone the supply chain trusted enough to not use e-bay or Amazon or even alibaba? Sure, the FBI sold compromised cell phones to criminals in the US, but still. If Israel doesn't have dozens of highly placed spies in the Pentagon I'd be surprised.
I do like the apparent confirmation that Israel has nukes, something that Israel has long been wishy-washy about.
