Last year, Afghan journalist Najibullah Quraishi made an extraordinary reporting trip for FRONTLINE that led to the award-winning film Behind Taliban Lines. This year, once again, Quraishi journeys deep into enemy territory--this time to meet a different band of militants and foreign fighters who say they are loyal to Osama Bin Laden and are readying a new offensive against coalition forces. As the United States faces a major strategic review in Afghanistan, Quraishi's journey sheds light on a question of growing importance: Is Al Qaeda once again becoming a significant presence in Afghanistan? Following up, Correspondent Martin Smith talks about the future of Al Qaeda with terror expert Peter Bergen, the best-selling author of three books on Osama bin Laden and the "war on terror."
