First, our enemies were the natives, then they were the Nazis, then after a while it was the communists. Finally, at the pinnacle of what we’re calling civilization, our enemies are the Islamic terrorists. Our enemies seem to change over the course of history along with our ways of fighting them. But what hasn't changed is government profit; politicians and leaders seem to always be getting richer by the blood of our soldiers. Makes you wonder who the real enemy has been all this time.
