Whats the differennce between a patriot and a terrorist?
The patriot won. The terrorist lost.

The winner writes the history book and assigns the labels.
Defining by tactics is not useful. As repulsive as I find it for someone to hijack a civilian plane and fly it into a building full of civilians, it is just as ugly a tactic as dropping a 70/30 mix of incendiary bombs / anti-personnel bombs on a city built of bamboo and paper. Once war has been become the answer, it is foolish to fight with anything less than everything you have. "Rules of Engagement" are only justified if they serve to further speed victory.
The third, and final, victory by the Romans over Carthage should be the model by which we fight wars. If we are unwilling to take war to that level we should not be going to war.
