First, there are those who suggest that Afghanistan is another Vietnam. They argue that it cannot be stabilized, and we’re better off cutting our losses and rapidly withdrawing. I believe this argument depends on a false reading of history. Unlike Vietnam, we are joined by a broad coalition of 43 nations that recognizes the legitimacy of our action. Unlike Vietnam, we are not facing a broad-based popular insurgency. And most importantly, unlike Vietnam, the American people were viciously attacked from Afghanistan, and remain a target for those same extremists who are plotting along its border. To abandon this area now — and to rely only on efforts against al Qaeda from a distance — would significantly hamper our ability to keep the pressure on al Qaeda, and create an unacceptable risk of additional attacks on our homeland and our allies.
