Where would you rather be and what would you rather be doing?

It seems to me that Iran is spoiling for a fight for a reason, but why? Do they seriously think they could win? I think not. Kristol's comment that the U.S. is in retreat sounds suspect to me. I think it is more likely that something is happening on the ground in Iran. For some reason the U.S. thinks that the goal can be accomplished a different way than in Iraq. I've heard theories about forces in Iran that could topple the govenment due to resentment among the people. Why assume that because the B-2's don't have their engines running there is no plan?
