Terrorist groups plotting from safe havens on Afghanistan's borders are the greatest threat to our security. Yet the Bush administration let itself be distracted from Afghanistan: now the Taliban insurgency is growing stronger, and the weak government of Afghanistan is threatened. Failure in Afghanistan will again allow Al Qaeda to operate unchecked. The U.S. must redouble its efforts in Afghanistan: by hunting terrorists, by increasing troop levels, by reengaging allies, by increasing reconstruction efforts, and by protecting and supporting the people of Afghanistan.
