Nuclear weapons, along with chemical weapons, are things that mankind should have never invented. Though I do believe that back when the two superpowers, the U.S. and the U.S.S.R. were fighting each other through surrogates all over the world, the fear of those weapons kept them from actually facing each other openly, thus avoiding WWIII. Had there been no nukes, but only conventional weapons during the 60's, 70's, and 80's, I do believe a confrontation between the U.S. and the U.S.S.R. would have been more likely. Now with Iran, their leaders are a bit more fanatical, sponsoring and arming terrorist organizations around the world, taking over the embassy of another nation in their country, I believe if they develop nuclear weapons, that doomsday clock will be closer to midnight than it ever was throughout the entire cold war as their leaders seem to be more religiously fanatical than W would ever be.
I do hope that we, the U.S., or the Israelis, do something to prevent them from doing so. I really hope that their intelligence services pinpoint exactly where our aircraft should drop their bombs or where our commandos should strike and put an end to Iran's nuclear ambitions. The problem is that we all believe that the CIA is full of Jack Bauer's, when it's actually full of Valerie Plame's. But even so, if Iran really wants to go to war against us, I say they should bring it on.
