Western sanctions have completely failed as Iran has speeded up uranium enrichment while moving equipment far underground into hardened bunkers. Obama thinks it's OK to say that "all options are on the table" and yet fails to commit to any deadlines or redlines. The redline is NOW and Israel is moving towards a unilateral strike having begged the US three times now to set a deadline. The window of opportunity is closing and there is no element of surprise this time. Iran KNOWS that Israel will be coming and so their missile defense systems are prepared along with their AF and intent to counter immediately with a missile barrage. The Iranians will also try to bring Syria and Lebanon into the war which is expected to be multi-front lasting anywhere from weeks to over a month... or potentially turning into a massive regional conflict that could spread worldwide! The Russians have declared that they will fight any foreign intervention in Syria by the West, so what happens IF Israel does a pre-emptive strike on Syrias missile and AF assets??? By delaying a coordinated unified massive strike the US is gambling that Israel will not act alone. Big mistake IMHO...
