The Iran deal would work out only if there would be a regime change before the restrictions expire, and while 15 years are enough for the US it’s not enough for Israel considering that the Iranian nuclear program has started even before the revolution, then with the full support of the US.
While the documents should surprise no one their release by the Israelis was done to make it harder for Iran to continue to run “we never worked on nuclear weapons” story they at least from Israel’s point of view manage to successfully sell to quite a lot of people.

Iran signed the Nuclear Non-Proliferation Treaty (NPT) in 1968 and ratified it in 1970. To date, Iran has never built a single nuclear bomb but only proven it can through enrichment should it choose to.
Israel's only real power in this case has been extrajudicial state-sponsored targeted assassinations. Its something that generally lands countries like Libya on the US terrorist embargo list, but Israel not so much.

As the story was told at a D.C. forum (sorry can't remember which one, but it was w/i the last year):
1a) not only was U.S. representation excluded from bidding on their project(s), but the Chinese and the Russians were allowed to.;
1b) if the U.S. was excluded from bidding, and therefore uninvolved in the project(s), it would not be able to "monitor" it;
2) the Saudis were supposedly citing Iran's ability to enrich uranium, and saying that that therefore allowed them (the Saudis) to do so, too, because their program was also "only for peaceful purposes."
