A nuclear Iran is no doubt a serious global threat…

But then again, the U.S. with nukes is a serious global threat. As is Russia, China, India, Pakistan, Gr. Britain, France, Israel, N.Korea, etc...etc...etc.

I think the United States must be EXTREMELY careful in acting unilaterally against Iran. We are talking about a country with a very effective and well-established human intelligence network. Not to mention that Hezbollah and Islamic Jihad are at their beck and call. I would say it is extremely likely that the U.S. would be targeted for a terrorist attack in the event of any unilateral military action against Iran on our part.

Having said that, I think the real threat of a nuclear Iran is to Israel, not the U.S. (other than the threat to our country's drug of choice - oil) It's likely that Israel also has better intelligence than we do on the extent and location of Iran's nuclear facilities.

My bet is that when Israel deems that the Iranian nuclear program has gone too far, they will act themselves to attempt to put an end to it, and won't ask us for permission. Will this start a full-scale military conflict in the region? Probably. Will it start WWIII? Possibly. But I would like to believe that cooler heads would prevail.

Whatever the outcome of the situation in Iran, I find it highly hypocritical for the U.S., or quite frankly any of the current nuclear powers, to lecture Iran or any other country on non-proliferation. How can we tell other countries not to develop nuclear weapons when we are taking absolutely no serious steps to reduce our own nuclear arsenals?
