I got it wrong, didn't I?
You know better than me - it was actually Robert Oppenheimer who uttered those famous words from the Bhagavad Gita when the Atomic Bomb successfully exploded on cue.
But actually Himmler never went anywhere without his own leather bound copy of BG - even slept with it at night.
It was the moral staff he leaned on to kill , kill and kill again without getting emotionally involved.
He paraphrased its main message quite closely in his famous Posen Speech, as he steeled the SS elite to do 'their painful duty' and kill every last Jew on the planet, children and all -- for the greater good of the greatest number - Himmler-Hindu-Utilitarianism as it were.
We see this same 'painful duty' line in the contemporary recorded and later re-counted justifications of the key participants for their actions in Aktion T4 and in the organized killings of Romas, Slavs and Homosexuals as well.
Menwhile, in the Allied World, Einstein also thought highly of this book and its main message : the self-sacrificing Will-To-Duty on behalf of Mankind , as did Ghandi and Herman Hesse.
The triumph of sheer willpower, laid out in various forms, had a wide appeal across much of the world's educated elite in the years from the 1880s to the 1980s.
I repeat: WWII was a fight within a family.....
