from Scott Horton's blog at Harper's:

my sense this week is that the roll-out for attacks on Iran has, to the great distraction of its sponsors, not gained the sort of traction that they envisaged for it. I am therefore pulling back on the prospects for the Cheney air war on Iran before the end of the Bush presidency, putting this again at a break-even proposition. Here are some of the points for the pushback.

In short, Horton raises three points: the red state heartland would not fair well under $7 oil, Admiral Fallon's speech as the center piece of the military pushback, and apparently, the Israeli's are backing off from the necessity of war with Iran.
