What if you had beaten the crap out of your neighbor down the street's husband, and gotten him thrown in jail for something he didn't do. Then you install your drunken cousin Steve as the new Dad of the house and he beats the crap out of the kids and his new wife. Then they all rebel and hold Steve hostage as long as you swear on the bible, you will never interfere in their domestic affairs again. Then you pay the neighbor next door to them, to massacre all their children, and you give him guns to do it. They eventually beat up and brutally maim the neighbor, after having lost a bunch of children. Then you go and conquer the neighbors on both sides of them with guns pointed out their house...and now they are stock piling weapons.
I think that is a more accurate description using the neighborhood analogy when applied to US-Iran relations. We've tried your jingoist kill-em-all approach nincompoop, that's why we have these problems with Iran in the first place. I don't think staying down that course will get us anything else - but more problems.
In World War III, noone wins, everyone loses. You forget that even third world countries have nukes now?
