I'm becoming slightly more optimistic that it won't happen, possibly for no good reason.  It's only because if they truly think a fast bombing gets them regime change, they should have done it already.  Every month they wait makes it harder, from new Iranian AA, to gas prices hitting $5/gal if the U.S. has a reprise of last year's hurricanes, to what happens if Bush gets into the 20's.  Also if the Russians fuel Bushehr then it essentially becomes unbombable.

I'm sure they want to do it, but somebody or something may have stopped them.
