"In return, what we would do would be to open up the spigot a little bit for a very modest amount of relief that is entirely subject to reinstatement if, in fact, they violated any part of this early agreement. It would purchase a period of time - let's say six months, during which we could see if they could get to the end state of a position where we, the Israelis, the international community could say with confidence, Iran's not pursuing a nuclear weapon," he added.
