But Iraq possessed no WMDs. All the supposed "evidence" for said WMDs originated from a single blatantly deceitful PowerPoint presented to Congress. If Bush was smart, he would have investigated a bit before launching a full-blown invasion of a sovereign nation. And, the invasion did more harm than good. After Saddam fell, the power vacuum created caused multiple terrorist groups to rush in, including the Taliban, Al-Qaeda, and ISIS. Had Saddam stayed, he would likely have been deposed in the Arab Spring, with no resulting power vacuum.
