To elaborate briefly on what I've written below. 

I think you can understand the relationship between war and the Holocaust.

To elaborate: Hitler was a jive-ass mother-fucker. He understood that “waging war” was a socially acceptable form of behavior. This is what “great leaders” do. They wage war in order to become “conquerors.”

in the process of waging war (the dream of conquest), one can require that one’s own soldiers die; that they become "obedient unto death." This goes without saying. This is what the phrase “obedience unto death” meant. In waging war, soldiers were expected to keep going, to follow the Hitler's orders, to be obedient even if it meant sacrificing one’s own life.

But then, jive ass mother-fucker that Hitler was, he reflected: “Well, if society gives me the right to sacrifice my own soldiers in warfare—if this is considered socially acceptable—why would I not also be entitled to sacrifice the life of Jews, enemies of the German people?"

Warfare is the independent variable, the Holocaust the dependent variable. Another form or manifestation of killing human beings in the name of the nation-state.

Once one understands that the essence of war is “sacrificing one’s life” (obedience unto death) rather than “male aggression,” it all makes sense.

But soldiers and men everywhere love the idea of “male aggression.” It makes men feel that they are “bad mother-fuckers” rather than the submissive wimps that they are--who can’t resist following the orders of their “leader.”
