Some influential retired Army generals include David Petraeus, Wesley Clark and David D. McKiernan. These generals all had respected careers in the U.S. Army, and Petraeus and Clark both went on to prominent political careers.
David Petraeus was the former director of the CIA, but prior to his ill-fated political career, he was a lauded general in the Army. Petraeus graduated from West Point in 1974, going on to a distinguished military career that culminated in his position as leader of the military surge in Iraq under George W. Bush. Petraeus became director of the CIA under Barack Obama, but he resigned from the position in 2012 after the discovery of an extramarital affair.
Wesley Clark spent 34 years in the U.S. Army, rising to the rank of four-star general and becoming Supreme Allied Commander and Commander in Chief of the U.S. European Command. Clark is notable for commanding Operation Allied Force, which prevented massive ethnic cleansing in Kosovo. After his military career, Clark ran as a democratic presidential nominee in 2004 before dropping out of the race and endorsing John Kerry.
David D. McKiernan led an illustrious military career commanding all allied ground forces during the 2003 invasion of Iraq. McKiernan also held concurrent positions in Afghanistan as Commander of the International Security Assistance Force and Commander of U.S. Forces in Afghanistan.
