That second video I think comes the closest to what he means, and even then the discussion on communism is pushed to the side for what Japanese Jared really wants to talk about: the destruction of White societies via the idea that negroes aren't functionally retarded.

He doesn't talk about who introduced or promulgated that ideas. Heck, Japanese Jared doesn't talk about who even systematically constructed the kind of communism that overtook those countries. He doesn't even give a name.
