According to CNN, one of the documents reveals that Israel maintains a nuclear weapons arsenal which, for decades, has been an open secret. This is highly controversial, as amendments made to US foreign assistance laws by US Senators Stuart Symington and John Glenn in 1976 make Washington's huge military aid to Israel illegal because Tel Aviv is not a signatory of the Non-Proliferation Treaty. But successive US presidents since Richard Nixon, including Joe Biden most recently, have agreed with their Israeli counterparts to never acknowledge Israel's approximately 90--300 nukes.
