A fascinating little moment on Fox News Sunday today. Bill Kristol airs the idea that if Obama looks as if he will win the election, Bush or Israel may be more likely to attack Iran before next January. Bush could say: Obama made me do it! Kristol also raises the prospect of Saudi Arabia and Egypt going nuclear in response to an Obama presidency. I think we'll see many more of these dire warnings if Obama looks like the next president - and he's increasingly the favorite. But why do I find the hysteria not so effective this time around? Maybe it's because the period in which we could have stopped Iran's nuclear ambition is now behind us.

But could it happen? Could Bush bomb Iran before the next election and create a sense of international crisis that could cause voters to swing back to McCain? From everything we know and Bush and Cheney, the answer, surely, is yes. His failed policies have left only one option to prevent Iran's going nuclear: war. And Bush must be chafing to see how his legacy could be dramatically changed if Obama wins. We could be facing the mother of all October surprises.
