In their minds, the murderers and accomplices of Germany, and Poland, and Hungary, and so many, many other places didn’t do something evil. They convinced themselves it was the right thing to do, the thing they had to do.
That’s what FBI Director James Comey said with an absolutely straight face at the US Holocaust Memorial Museum’s 2015 National Tribute Dinner, and he repeated them in all seriousness in his Washington Post editorial at the link. Poles as a society were accomplices in the holocaust.
This is the same FBI Director who has demanded FBI access to the encryption keys of messages that American citizens send to each other so that his FBI can snoop at will.
