It came from at least 4 angles.
1) The Vassily Grossman NKVD anti-German propaganda and revenge angle.
2) The right-wing Zionist angle with Jabotinsky's early speeches and Peter Bergson (Hillel Kook) in USA. As well as a general Zionist angle with so many people, but to name one: Josef Rosensaft at Belsen.
3) The Eisenhower angle and his Psyche Warfare moves at Merkers/Ohrduf/Buchenwald.
4) There's also a Warsaw ghetto/resist deportation by instilling fear angle with Jacob Berman/Emmanuel Ringelblum/Rachel Auerbach.
