Bruce Riedel and Michael O'Hanlon. "Why we can't go small in Afghanistan". USA Today. September 4, 2009: "Once the Taliban is back in power in Afghanistan, al-Qaeda will not be far behind. Our top nemesis will be able to salvage a victory in the very place from which it launched the 9/11 attacks eight years ago. Al-Qaeda will have its favorite bases and sanctuaries back, as well as a major propaganda win."
