Is [General David Petraeus] confident that the Afghan army can take the lead from U.S. forces by NATO's 2014 deadline? After nine years of war fewer Afghans support a U.S. presence in the country and fewer believe that the United States makes their country any safer, according to a new ABC News/ Washington Post poll - something that the U.S. clearly" needs to continue to work on, Petraeus said. Petraeus said he is "not sure" why support for the U.S. presence has slipped over the last year. Petraeus said it is "hard to say" how much of Afghanistan the Taliban control. He also acknowledged a "resilient" enemy that regenerates, which is why he said this war will take a "sustained, substantial commitment." So what does the end of our "substantial commitment" in Afghanistan look like? Victory will not come with the U.S. planting a flag on a hill and going home to a victory parade, Petraeus said. "It looks like an Afghanistan that can secure and govern itself. And it's one that incrementally demonstrates the ability to do that, not suddenly. Between the summer of 2011 and the end of 2014 there will be, again, a series of transitions, starting most likely at districts, not in overall provinces," he said.
