I think it's important to remember in all of this rather sudden war fever that much of Washington's sudden fixation on it is due to a timely visit by arch warmonger Benjamin Netanyahu, leader of Israel's 2nd most right wing party. Recall that Israel has so
lost their heads in right wing hysteria as of late that Israel's biggest left-of-center party placed fourth in the 2009 elections, after the centrists, the conservatives, and the hard right wingers.
Netanyahu really, really wants war with Iran, and he really wants a Republican president, someone sufficiently beholden to evangelical millenarian wackadoos that he'll fight whomever Netanyahu tells him to.
Netanyahu came to Washington and essentially demanded that either we pick a fight with Iran, or they will. Think about that for a moment, pondering how Netanyahu believes we'd throw our kids on that bomb to save his.
In any case, expect to see a lot more of him over the next nine months as he continues to meddle in American electoral affairs.
