In 1920, Churchill wrote a full page article for the Illustrated Sunday Herald detailing the Jewish involvement in the Russian revolution:
"This movement amongst the Jews (the Russian Revolution) is not new. From the days of Spartacus Weishaupt to those of Karl Marx, and down to Trotsky (Russia), Bela Kuhn (Hungary), Rosa Luxembourg (Germany) and Emma Goldman (United States), this world wide conspiracy for the overthrow of civilization and the reconstruction of society on the basis of arrested development, of envious malevolence, and impossible equality, has been steadily growing. It played, as a modern writer, Mrs. Nesta Webster, has so ably shown, a definitely recognizable part in the tragedy of the French Revolution. It has been the mainspring of every subversive movement during the Nineteenth Century; and now at last this band of extraordinary personalities has gripped the Russian people by the hair of their heads and have become practically the undisputed masters of that enormous empire. There is no need to exaggerate the part played in the creation of Bolshevism and in the actual bringing about of the Russian Revolution by these international and for the most part atheistic Jews. Moreover, the principal inspiration and driving power comes from Jewish leaders."
When it came to the conduct of the Civil War in Russia Churchill personally warned White Army General Denikin, whose forces Britain was funding and equipping and who were undertaking pogroms against Jewish communities, that “my task in winning support in Parliament for the Russian Nationalist cause will be infinitely harder if well-authenticated complaints continue to be received from Jews in the zone of the Volunteer Armies“. General Denikin ignored Churchill’s warnings, and the pogroms continued.
