A US Navy nuclear reactor in Pennsylvania supplied the plutonium for the first couple of Israeli A-bombs which were assembled just before Israel launched the 1967 War. Ace up their sleeve.
Then, after the 1973 War, when Israel blackmailed Nixon into resupplying the IDF as Syria was about to overrun the Golan Heights, CIA Director G.H.W.. Bush Sr. evened the score by agreeing to a nuclear deal with the Saudis. Bush entered into the "Safari Club" arrangement that funded the Pakistani nuclear program and a Saudi global paramilitary capability that became al-Qaeda. A.Q. Khan provided Iraq and Iran with centrifuges, which later became the pretext for military operations against both. Meanwhile, the US continued to supply nuclear weapons technology to Israel through the proliferation ring that Netanyahu was reportedly working for.
Let's not forget, that during the Reagan-Bush years and into the Clinton Administration we also supplied China with modern, lightweight W88 MIRV warheads and related ICBM and satellite technology.
We seem to be the world's nuclear Wal*Mart. We're practically giving it away!
And, we have the chutzpah to accuse Iran of violating the NPT.
