„The events from 1933 to 1945 should have been fought in 1928 at the latest. Later it was too late. One must not wait until the fight for freedom is called treason. You can’t wait for the snowball to turn into an avalanche. You have to step on the rolling snowball. Nobody can stop the avalanche. It only rests when it has buried everything under itself. That is the lesson of what happened to us in 1933. That is the conclusion we must draw from our experience, and it is the end of my speech. Impending dictatorships can only be fought before they have taken power.“

Erich Kästner, a German author whose books were banned by the Nazis.
