A nuclear deal with Iran does not yet exist, and therefore Prime Minister Benjamin Netanyahu cannot know what is in it, US State Department Jen Psaki said on Thursday. "We've seen this movie before," Psaki said of skepticism from leadership in Israel over Iran nuclear talks. Earlier this week Netanyahu said that the current proposal to Iran would endanger Israel. "It would enable Iran to breakout to its first nuclear device within an unacceptably short time," Netanyahu told a gathering of American Jewish leaders in Jerusalem. "It sounds like he knows more than the negotiators," Psaki said, responding to claims that Netanyahu knows the details of the deal.
