If, (and it's a huge "if") there is to be peace in Iraq, it will be after cleaving the nation into three states. THAT task could have been done with the stroke of a pen at the conclusion of Gulf War I with no invasion of Bagdad.
Of course Saddam was a bad guy. The world is full of bad guys. If it's gonna cost $7 trillion and more than 3,000 lives to kill each one we need to rethink this nation building thing.
Sadly, the dyslexic miscreant in the Whitehouse thinks history will remember him as a great visionary.
