Stanley Allen McChrystal is a retired United States Army general best known for his command of Joint Special Operations Command in the mid-2000s. His last assignment was as Commander, International Security Assistance Force and Commander, U.S. Forces Afghanistan . He previously served as Director, Joint Staff from August 2008 to June 2009 and as Commander of JSOC from 2003 to 2008, where he was credited with the death of Abu Musab al-Zarqawi, leader of Al-Qaeda in Iraq, but also criticized for his alleged role in the cover-up of the Pat Tillman friendly fire incident. McChrystal was reportedly known for saying and thinking what other military leaders were afraid to; this was one of the reasons cited for his appointment to lead all forces in Afghanistan. He held the post from June 15, 2009, to June 23, 2010.
Carl Philipp Gottfried von Clausewitz was a Prussian general and military theorist who stressed the "moral" and political aspects of war. His most notable work, Vom Kriege , was unfinished at his death. Clausewitz was a realist in many different senses and, while in some respects a romantic, also drew heavily on the rationalist ideas of the European Enlightenment.
