Yes. Absolutely.
Our leaders KNEW there were no WMD before the war. A CIA official sat in the Oval Office and told Bush, Cheney, and Rice.
Hillary Clinton could have known that a prominent Iraqi defector during Bill Clinton's presidency told his debriefers that Saddam Hussein had destroyed his WMD.
Results of the war: 800,000 orphans, over 1 million dead from all cause, and depleted uranium creating severe birth defects.
