The Washington Post reports:
Gen. David H. Petraeus relinquished his command of U.S. and NATO troops in Afghanistan on Monday, handing the reins to Marine Gen. John Allen as the United States and its allies begin to withdraw troops from the country where they have waged war for nearly a decade.
Petraeus ends his tour in Afghanistan without conclusive signs that the counter-insurgency strategy he helped design has turned the tide in the war against the Taliban. The more than 140,000 NATO troops under his command have weakened the insurgency in some of its key strongholds in the south, but other parts of the country remain treacherous, and Taliban leaders still operate with relative impunity from Pakistan.
General Petraeus will retire from the military and take command of the CIA.
