I think you make some great points, but to paint those in washington who don't want a nuclear Iran as fools with some irrational, fantastical vision of the Iranians being "madmen", or by extension lapdogs of the Israel lobby, is not very fair or realistic. The president, whoever it may be at any given time, doesn't have the luxury of seeing Iran as a single smiling dignitary in George Clooney blazers, or the masses of pro-western students protesting him. Iran has been the biggest state sponsor of terror for decades. There's no way around that. Right now in 2012, the president still has to watch coffins come home, packed with dead bodies of soldiers for which you don't need too many degrees of separation to attribute to Iranian culpability. It's kind of easy to sit back on our level, with our information, seeing only BBC news of crippling US/EU sanctions and flowery UN speeches and say, "What's the big deal?". But put yourself in the shoes of the president, or the chairman of the joint cheifs of staff, or the director of the CIA, and ask yourself...............is a nuclear Iran really something we want to happen? Given what they are actually doing, and having been doing for decades against America? We in the states might not be feeling the heat of an Iranian threat, but I assure you, many Americans in uniform have and are.
And for what it's worth, I think we can and should make historical concessions for why Iran hates us, while still remaining firm on not letting them get their hands on weapons that could kickstart armageddon. The two aren't mutually exclusive. I like that we have a president who understands that real diplomacy involves being honest about our mistakes, and doesn't see weakness in having that kind of honest discussion with foreign leaders. I also like that we have a president who, when presented with all the facts and the reality of the world, didn't stay stagnant in his comfy campaign rhetoric that diplomacy is all that is needed. A nuclear Iran isn't a benign threat, and anyone who argues that does so against all evidence.
