You could also look at past wars on terror and how unbelievably unsuccessful they have been. As long as you are fighting a concept and not a defined enemy you can't win. The reason being, you can't gauge success. We can say "We have defeated Iraq," and be correct. Some day, we may be able to say "We have defeated Al-Quaeda." But we will never be able to say "We have defeated terrorism." That's the issue I have with the WoT. We should have learned our lesson with the War on Drugs.
