I wonder how old the rest of the commentators are. I watched the Shock and Awe campaign. I watched Saddam fall. I remember thinking this is great. Years later, I understand it was a complete folly. Removing Saddam in itself was good but what it did the wider region was not good.
I am old enough. Iraq is not perfect today but so much better than it was. Go talk to Iraqis and see for yourself.
It costs us some time, money and lives to get to this point. But Saddam (a tyrant who killed his own kind in masses with gas and started wars with neighbors) staying in power would have been way worse for the wider region.
