"We had al-Qaida down on the 10-count, and we let it off the mat," Mansoor said.
After his deployment as XO to Petraeus, Mansoor retired in 2008 and went on to publish two memoirs detailing his experiences during the surge. He's now an associate professor at Ohio State University, where he teaches military history. Speaking at a discussion Wednesday at American University in Washington, D.C., Mansoor assessed the Obama administration's approach to Iraq and criticized several key areas.
Citing a general "unraveling of the security situation around the world," Mansoor stressed the need to "know who your enemy is."
