Terrorism is not the problem
The 9-11 Commission report says it. Prof. Record at the Army War College says it. Terrorism, or assymetric warfare, is not what we are fighting against. We are fighting against a virulent strain of sadistic Islamic radicalism. Oh yeah, and against whoever is in Iraq right now.
Terrorism is never pretty, but there are times when assymetric warfare is not only acceptable, but good. Parisian resistance to Hitler for instance.
Fight enemies, not tactics.
