On October 31, 2008, Petraeus assumed command of the United States Central Command (USCENTCOM) headquartered in Tampa, Florida. Petraeus was responsible for U.S. operations in 20 countries spreading from Egypt to Pakistan—including Operations Iraqi Freedom and Enduring Freedom. During his time at CENTCOM, Petraeus advocated that countering the terrorist threats in the CENTCOM region requires more than just counter-terrorism forces, demanding instead whole-of-governments, comprehensive approaches akin to those of counterinsurgency. One of his closest colleagues said that Petraeus knew that defeating an insurgency required living among the people, convincing them that we were better than the insurgents. "can't kill 'em all ... . [You can't kill your way out of an insurgency. ... You have to find other kinds of ammunition, and it's not always a bullet."
