Do we actually WANT our military to be "good Nazis", and obey their superiors, even when their superiors violete the Constitution or the Declaration of Human Rights?
The military is no longer the job of last resort, as it was back when petty thieves were told that they could choose between going to prison ot joining the Army of Marines. People with room temperature IQ's are no longer the average soldier, not even at the lowest level.
It might be that in days past, the commanding officers wanted their underlings to be unquestioning, mindless droids. But of course, that is hos utter disasters like the Charge of the Light Brigade and the Somme Offensive occurred. The generals in charge were fools, and huge numbers of troops died from their foolishness. The British invasion of Gallipoli, commanded by Winston Churchill was based on ancient military campaigns in the classical age. Winston did not take into account that the Turks had mortars and machine guns, while the Greeks only had spears, arrows and swords. Winston did not get killed or maimed like over half of the Aussies and Kiwis, who he thought of as cannon fodder. Winston was not there. And if anyone questioned him, including his generals, they were ignored, because Winston was from the upper class.
Just because the old "tear them down and build them up like robotroops" worked at one time, that does not mean that it is the best way to do it now, ot that it has ever been the best method.
