The Nuremberg process initiated 3,887 cases of which about 3,400 were dropped. 489 cases went to trial, involving 1,672 defendants. 1,416 of them were found guilty; less than 200 were executed, and another 279 defendants were sentenced to life in prison.
"Evil, I think, is the absence of empathy"
- Captain G. M. Gilbert, the Army psychologist assigned to the Nuremberg trials¹
Roger Stone - Hermann Göring
¹ Captain Gilbert interviewed most of the defendants in-depth during the Nuremberg rials, with his interview with Göring being noteworthy:
Göring: Why, of course, the people don't want war. Why would some poor slob on a farm want to risk his life in a war when the best that he can get out of it is to come back to his farm in one piece? Naturally, the common people don't want war; neither in Russia, nor in England, nor in America, nor for that matter in Germany. That is understood. But, after all, it is the leaders of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship.
Gilbert: There is one difference. In a democracy the people have some say in the matter through their elected representatives, and in the United States, only Congress can declare wars.
Göring: Oh, that is all well and good, but, voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked, and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same way in any country.
