I also think it's interesting that the Iran diplomatic front has been so quiet for so long, until now. Usually it's some publicized revelation about their progressing nuclear capabilities that sends the state department into a frenzy of trying unsuccessfully to drum up international support for increasing the pressure on Iran. What seems clear is that behind the scenes the Obama administration likely remains under constant pressure from Israel and Saudi Arabia to do more, but there hasn't been any new public hook for a long time, to hang the hat on for upping the stakes. One possibility is that there is some new undisclosed information about Iran's nuclear program, something delicate and/or frightening enough that they don't want the American people to know about it, but something that has encouraged Israel and Saudi Arabia to help the White House lay a foundation for military action. In that sense, I agree with Gonk that the way Clinton and Biden sprang into action is unnerving. And as much as I hate to admit it, I've become convinced in the last few years that Obama's foreign policy is fundamentally as evil as George Bush's, but potentially even more insidious.
