For two years now, John McCain has been entirely consistent on Iran: every last statement he’s made–at least, those that I’ve seen–has been (a) fabulously uninformed and (b) dangerously bellicose. He’s still at it, apparently. There is no question that President Obama’s more prudent path is the correct one right now. There is also no question that the neoconservatives are trying to gin up this situation into an excuse for not engaging with the Iranian government in the near future–and also as a rationale for their dearest, looniest dream, war with Iran.***
The point is, neoconservatives like McCain and Wehner just can’t seem to quit their dangerous habit of making broad, extreme statements based on ideology rather than detailed knowledge of the situation in Iran and elsewhere. This was always the main problem with McCain’s candidacy–he would have been a trigger-happy President, just as Wehner’s old boss, George W. Bush, was. We are well out of that.
You really do have to read McCain’s twitters to get a sense of how rambling and incoherent his line of thought is on the current Iranian situation, and we really dodged a bullet with the last election. If he and the Wasilla wingnut were in office right now, the US strategery would continue to be formulated by former Weekly Standard interns, McCain would be making all sorts of foolish bellicose statements and probably would be moving troops in Iraq to the Iranian border, all while Palin would be issuing vague statements about being able to see Tehran from her house while praising the Iranian focus on abstinence-only education.
