Ain't gonna happen. Not an Iraqi like war though. I've seen Generation Kill just now, I doubt the US army is up for another likewise strike.
First of all, current US government's policies seem to be adverse from more war. Secondly, Rath's post was pretty intelligent - if anything the US will provoke or support a revolution.
Israel is the biggest bet but altough they can easily take on Iran, direct war might leave their forces stretched thin and other nations are still waiting for their chance to wipe Israel of the map. Open warfare will most likely agitate all the hives around them.
Plus, don't expect too much help from the UN. Germany, the UK, France, they are all still pissed of about the passport-debacle.
