In June, U.S. President Barack Obama acted swiftly and wisely in relieving General Stanley McChrystal of command of the war in Afghanistan. In removing McChrystal for making disparaging comments about civilian leaders in a Rolling Stone article, the president reasserted the constitutional principle of civilian control of the military.
