Where does this idea that guerilla warfare is invincible come from? It makes no sense at all. Guerilla warfare is a practice of conventional war with modified tactics. You have organized troops with standard military equipment, but with a less centralized structure and a much more defensive posture in combat. Troops are limited in supply, they are not unassailable. The U.S. Army infantry fights its physical battles like a guerilla force, we are very defensive by practice, but the CCC is more like a centralized, traditional military. We can maintain our traditional structure because of our technology, and in this layout and with said technology, we actually have a double advantage. You're probably thinking more of a resistance movement than an actual guerilla war. I would say though that the chances of the Iraqis resisting us are near nil, they seek to benefit from Saddam's removal. I suppose you would say we lost in Afghanistan? I haven't heard of an attack against any U.S. base in months, and the people are better off. Afghanistan is probably one of the most friendly countries to us in the world right now.
