Ether we win it and change the course of history for the better. Or, we cut and run like Zinni and others like him are wont to do, and we will have more 9/11's for the foreseeable future.
I personally don't care what anyone thinks or what/who gets broken or killed as long as it is noone in these United States.
Noone is all knowing to the point that they could have predicted what would happen after Saddam was eliminated. He, like Tito, kept the lid on all the factions through multiple means including fear. So the place fell apart. There was nothing there anyway.
Hey, I've seen some predictions from several years before the invasion that turned out to be fairly accurate, but so what? Neither they nor anyone else had a silver bullet to make it work. So the complaints about "planning for the peace" still amount to hand-wringing that invasion never should have been attempted in the first place. And that goes back to what would be the consequences of Saddam still in power in 2006? Not good.
