Our strength is our quickness and our brutality. Genghis Khan had millions of women and children hunted down and killed, deliberately and with a gay heart. History sees in him only the great founder of States. What the weak Western European civilization alleges about me, does not matter. I have given the order – and will have everyone shot who utters but one word of criticism – that the aim of this war does not consist in reaching certain designated [geographical] lines, but in the enemies' physical elimination. Thus, for the time being only in the east, I put ready my Death's Head units, with the order to kill without pity or mercy all men, women, and children of the Polish race or language. Only thus will we gain the living space that we need. Who still talks nowadays of the extermination of the Armenians?
Sadly, that is an entirely bogus quote. Really. Even though it’s been “quoted” a million times on the internet, there is no evidence that Hitler ever said it or wrote it. It first “appears” long after Hitler was dead.
“The problem with internet quotes is that so many of them are false.” -—Abraham Lincoln
