Argument: US must show resolve in Afg. to beat extremism
David Brooks. "The Afghan Imperative". New York Times. September 24, 2009: "Since 1979, we have been involved in a long, complex conflict against Islamic extremism. We’ve fought this ideology in many ways in many places, and we shouldn’t pretend we understand how this conflict will evolve. But we should understand that the conflict is unavoidable and that when extremism pushes, it’s in our long-term interests to push back — and that eventually, if we do so, extremism will wither."
