Furthermore, we should have never been in Iraq in the first place. Iraq had no connection to Al Qaeda, was not an immediate threat to US interests, nor did they possess weapons of mass destruction. The Iraq War was a costly distraction from the war against Al Qaeda, and helped Osama Bin Laden escape capture/kill until President Obama redoubled our efforts to get him.
Most importantly, thousands of American lives were lost in this war. First, because the initially foolish, stupid invasion, and then from the mismanagement inflicted by President Bush and his leadership team. These poor decisions also led to the loss of thousands of innocent Iraqi lives.
The invasion of Iraq and the subsequent mismanagement of the occupation of Iraq will go down in history as one of the darkest, most horrible moments in American history.
Thank God it is over.
