Gen. John Allen took over command of American and coalition forces in Afghanistan on Monday from Gen. David Petraeus, assuming responsibility as Afghanistan's international allies draw up exit plans from the nearly 10-year conflict, according to AP. Allen said that the drawdown of U.S. forces that started earlier this month and the transition of some areas to Afghan control this week does not mean that international forces are easing up in their campaign to defeat the Taliban insurgency. "It is my intention to maintain the momentum of the campaign," Allen said at the handover ceremony in the Afghan capital. He said however, that he does not expect the fight to be easy. Allen, who was promoted to a four-star general shortly before the handover ceremony, takes over from Petraeus, who commanded international forces in Afghanistan for one year and is retiring from the military to become the director of the Central Intelligence Agency.
