I read from online that before defeat of Nazi Germany, there was skepticisms of ongoing Holocaust of Jews by Nazi Germany with some even dismissing it as Communist Propaganda.
My question is to what extent were the Western Allies such as US, UK and France were aware of the Nazis plans of genocide of the Jews during the course of the entire war?
