Old wmd from the Iran/Iraq war[that later the Bush admin didn't take responsibility in medically helping our boys] was not reason enough to 'invade' Iraq, nor was the destability of the region weighed against Iraq even having new weapons.
No matter how bad SH was, he still was more of a stabilizing force than we ever could have become, and a natural bulwark against Iran.
Nor was the costs of the invasion ever properly explained or reasoned. We will be paying for those miscalculations for generations.
Not only that but there has been no public review of the policies and practices of the intelligence failure in supporting such a intervention, nor has anyone been held accountable for such actions. As with the typical government actions.
SH invaded two neighboring countries, fired SCUD missiles at Israel, harbored international terrorists, practiced genocide against the Kurds, slaughtered hundreds of thousands of people, plotted to assassinate a US president.
He received is just reward IMHO. GWB won the war against this mini-Hitler in the Middle East and BHO surrendered Iraq. I am at least grateful SH received his just reward in the end and that he was captured, brought to trial, and had to be held into account for his massive war crimes, genocide, violations of international law, support of terrorism, and ethnic cleansing.
