In a rare extended interview, we speak to Michael Hastings, whose article in Rolling Stone magazine led to the firing of General Stanley McChrystal. Hastings’ piece quoted McChrystal and his aides making disparaging remarks about top administration officials, and exposed long-standing disagreements between civilian and military officials over the conduct of the war. The Senate confirmed General David Petraues as McChrystal’s replacement on Wednesday, one day after McChrystal announced his retirement from the military on Tuesday after a 34-year career.
