A report sent to the British government in 1918 by Mr. Oudendyke, the Dutch consul in St. Petersburg, said that "Bolshevism is organized and worked by Jews." The report was included in a pamphlet (click on the pic left) published as a government White Paper in April 1919 entitled Russia No. 1 (1919) A Collection of Reports on Bolshevism in Russia. However, the pamphlet was quickly withdrawn and reissued with various excisions and alterations made.
The Oudendyke report does not appear in the pamphlet left but if you do a word search on "Jews" you will learn of the tortures they perpetrated on the Russians and references that prove that the Bolshevics were Jewish.
