No, just Tehran. Regime change in Tehran (however it's accomplished) will make Syria (and Lebanon, and "Palestinians", and "insurgency" in Iraq) impotent. Would also help big time with Russia and China as their big client states in ME (Iraq and Iran) would be under new management. Of course, it would be much more difficult now as Dems will not be too anxious to call for action on Iran as they did with Iraq, but will blame whatever happens, or doesn't happen, on Bush... or at least Rumsfeld as a proxy.
Of course, the other way to settle Iraq is to take a step back and let the Shiites massacre the Sunnis.
And Sunnis killing Shiites. It's a little slow going, but we are already successfully doing that, just had to wait a while until Tehran is resolved, which may be a problem now. And it's not a "plan" you can run on or even clearly explain to electorate - you just hope they understand, but between DBM and ferile Dems...
I think, probably, Rumsfeld is going to have to go, now. He's become a liability. He's a great man, but his effectiveness is gone.
Bring in Lieberman. Especailly now. Gov. Rell can appoint his replacement.
