Yes, many of us may want to forget. Lots of pain and death and torture. For no good reason. But Krugman nails it: The Iraq Stain.
And we should not forget. And we should remember those who lied us into it, and carried it out, and those who now pretend that it wasn't all a terrible, easily avoided, debacle and tragedy...
"No, Iraq was also a moral cesspit. Not only were we taken to war on false pretenses, it was clear that this was done in part for domestic political gain. The occupation was treated not as a solemn task on which the nation’s honor depended, but as an opportunity to reward cronies. And don’t forget the torture." - P. K.
