How aware were the common people of the Holocaust and also how aware were the elite? If they were not did they become aware as soon as the war was over?
/u/commiespaceinvader has previously answered Did the Japanese know what Nazi Germany was doing during WWII?
/u/Lubyak and /u/Starwarsnerd222 have previously answered Why exactly did Nazi Germany & Japan ally with each other? which was later part of the AskHistorians Podcast.
More answers would be great.
