Since WWII, we have become too humane, Councilman. This sick, stupid, liberal attitude that you should fight war in a "humane", "kill-as-few-as-possible" manner is simply bull****. History is replete with examples of war that works. And the lesson that should have been learned is that you kill a whole ****ing lot of the enemy. Enough that they are too busy trying to scrape food together to give you ****. Not to mention they don't have enough people left to be much of a problem.
But we chose not to learn from history. We won't learn the history of our current wars either. We fight wars of occupation and instead of learning the lesson that we don't want wars of occupation, we will continue to do it. At least until someone who knows their history a bit better fights a war of annihilation and subjugation against us. And wins -----enter Islam
