WWII: What made you think about killing Hitler when the opportunity was presented?
Knappe: Probably his statement to General Weidling when Weidling was asking him for permission to break out and for him to go with us. General Weidling told me that Hitler had said that he did not want to die in the street like a Landstreicher. Landstreicher does not have an exact translation into English, that is why my book uses the word dog, but a Landstreicher is someone like a hobo or panhandler. Both of us had seen hundreds of German soldiers die in the streets during the war, and now Hitler was saying that he did not want to die like they died. My brother died from his wounds that he received in Russia. So, both of us were very upset by Hitlers use of this word. It was just such an unbelievable comment, especially to make that type of comment to a soldier. It wasnt until this time that I finally began to realize what sort of man we had been fighting for.
WWII: So, it was that one statement?
Knappe: Yes. I just had this impulse to shoot him. I wasnt worried about being executed afterwards, for I thought that I was a dead man anyway. We had recaptured some places from the Russians during the war and whenever we did, we almost always found that the German officers had been executed. So, I thought that the Russians would execute me after I was captured. Unconsciously, I realized that I couldnt afford to make Hitler into a martyr. This would have created another Dolchstosslegende orstabbed-in-the-back legend. [Joseph] Goebbels [Hitlers propaganda chief] would have made the most out of it. Im sure that he probably would have said that if the Fuhrer had not been killed by a general staff officer he would have found some way to save the German people.

It took SIX YEARS OF WAR, millions dead, and that ONE personally insulting statement FINALLY woke up this Nazi. This anecdote perfectly summarizes Trump supporters, and probably some of them would STILL support him even if he personally insulted them to their face. Sad sad sad.
