"Evil prospers when good men do nothing"

Jan Karski served as a courier for the Polish resistance during the Nazi occupation. He was the first to inform the governments of the United States and Britain about what was happening to Jews in occupied Poland. Karski had been to the Warsaw Ghetto and inside Bełżec. Millions of Polish Jews, and many others, died in the Holocaust. The truth of Karski's reports was doubted. Power Line quotes Walter Laqueur's explanation for that doubt:

Democratic societies demonstrated on this occasion as on many others, before and after, that they are incapable of understanding political regimes of a different character.... Democratic societies are accustomed to think in liberal, pragmatic categories; conflicts are believed to be based on misunderstandings and can be solved with a minimum of good will; extremism is a temporary aberration, so is irrational behavior in general, such as intolerance, cruelty, etc. The effort needed to overcome such basic psychological handicaps is immense.... Each new generation faces this challenge again, for experience cannot be inherited. (Walter Laqueur, The Terrible Secret: Suppression of the Truth About Hitler’s “Final Solution,”)

Unless we actually witness the piles of bodies or see the beheadings...

The world is a dangerous place to live; 

not because of the people who are evil, 

but because of the people who don't do anything about it.

Albert Einstein
