I have voted other, I would not want America to attack Iran, there's enough bloodshed in that part of the world as it is. It is evident that Iran (Syria and Pakistan) are over run with anti Western feeling and are supporting the radical elements in Iraq (the president of Pakistan is either a fool or a liar).
Such anti Western feeling cannot be smashed with an iron fist, in my opinion it would make the situation worse.
I'm afraid that Western governments will have to talk to governments that quite clearly hate them and all they stand for, it is the only way a peace (of sorts) will be achieved. The problem with that part of the world is that there are two sects of the same religion fighting for dominance, the Western world cannot understand it and are unable to intervene in a practical way. Western forces should get out of there and leave them to it. It would be likely that they would end up with extremist countries who could then be sanctioned by the rest of the world. Will there ever be peace, I doubt it, but why should Western soldiers give up their lives for a people who hate them so much
