"Complications abound in the region and hamfisted charges into the china shop (hows that for mixed metaphors?) are the last thing we are going to do. Of course, Nukes are the answers to every issue for some here."
Diplomatic efforts have no chance at all unless we could get China and Russia on our side and I don't see that happening. Iran will get a nuke unless we stop them with force. There comes a time when we need to realize that we aren't going to find a diplomatic solution that works. Should we keep looking for one until it's to late and Iran has a nuclear weapon?
Honestly I would rather use a nuclear weapon against Iran than allow Iran to get a nuclear weapon. Although I'm not saying that's what we should do if we do use force.
The US will NEVER use a nuke against Iran. If you expect any such response you do not understand this nation or its people.
