WWIII could start now due to the repercussions of our intervention. Bush had zero strategic goals beyond "remove Saddam." No one, and I mean no one, had a clue what to do once that was accomplished. If you can't outline the ways, means, and ends for that infamous "phase 4," then you shouldn't get involved at all.
Not true. Many people I know said we should just leave, and let the Iraqis solve the problem of Saddam's replacement.
They would have promptly acquired another strong man dictator to run that nation. The difference being, he would not mess with us anymore, nor would he mess with any of our interests.
But nobody in charge knew what to do, I'll grant you that.
