Perhaps the worst crime of all the Nazis committed was to make many of those who fought them lose a bit of their humanity. How many men returned from the war, broken, having seen and experienced things no human should ever have to, to do what had to be done?
“The aggressors always determine how a war is to be fought.If the defenders fail to match their opponents’ tactics they lose.WWII is a war that the civilized world just couldn’t afford to lose.”
Said another way: choose your enemies carefully. You are going to become just like them.
