How I would solve The Iran Nuclear Crisis

Soldiers are speculating that Iran's insistence on developing nuclear capability could lead to an invasion of Iran. In fact, we speculated about it when we were still in Iraq. I am not in charge nor do I ever plan to be, but if I were I would basically do what we are doing now. It makes sense - negotiations either work and the nuclear threat ends or they don't and the international community join forces to obliterate Iran. The beautiful thing is that building nukes isn't easy so everyone can afford to spend time on probably fruitless negotiations. (What we can't afford is to allow the loons in power in Iran to actually use the nukes.) In the course of negotiations we could impose sanctions over time and pressure China and Russia to cease arms sales to Iran.
The odd thing that people don't realize is that "the transformed" US Army would make short work of the Iranian army. Guerilla warfare is hard, standing armies are easy. All the things we can't do in Iraq we could do to Iran. Also, one would hope that the lessons learned in Iraq would prevent similar problems from cropping up in Iran.
Mostly, I am peeved at Iran for agitating the whole time I was in Iraq. And if they do force a conventional military invasion I am going to be more peeved if I get called back to fight.
