A near majority of Jews dominated the top ten to twenty leaders of the Russian Bolshevik Party's first twenty years and the Soviet Union's secret police was "one of the most Jewish" of all of its institutions. In Austria, the leaders of the Austromarxism movement were "virtually all" Jewish and Jews played a "central role" in the failed November 1918 coup d'état led by Egon Kisch and his Red Guards. During the German Revolution of 1918–1919 in the Weimar Republic, the Communist uprisings included Spartacus League members Rosa Luxemburg, Leo Jogiches, and Paul Levi, and Jews held indisputable prominence in its undertaking. The Bavarian Soviet Republic was headed by Eugen Leviné and had in it a minimum of seven other Jewish commissars. In the 1930s Jews controlled a "high proportion of the most sensitive positions" in Hungary, Romania, and Poland, including the Party apparatus, state administration, and especially the Agitprop, foreign service, and secret police. During the Cold War, Jews, mostly from Eastern Europe, accounted for 40–50% of the American Communist Party's membership, and counter to the denial of American Jewish publicists, Jews played a "disproportionately important role" in Soviet and world Communism until the early 1950s.

This is an interesting clip because Matt Walsh is basically fearless about every controversial topic, but notice how he won't even engage with the question. He mocks it and blows it off. He either didn't have an answer or didn't want to give one.
