Israeli officials say they won't warn the U.S. if they decide to launch a pre-emptive strike against Iranian nuclear facilities, according to one U.S. intelligence official familiar with the discussions. The pronouncement, delivered in a series of private, top-level conversations, sets a tense tone ahead of meetings in the coming days at the White House and Capitol Hill.
