To the original question: Hitler viewed all communists as Jewish led scum against the father land. How true that is I do not know, but he did state it time and time again.
Indeed they were mostly Jews but not against the father land.
The Bolshvik revolution seemed threatening by other democracies as well. As the capitalists of Britain, France and America, who saw the Communist success galvanising the left wing of their own working classes. The Jews were attracted to those ideas because the old order had little forthem. For them Tzarist Russia was mainly pogroms. And so on.
On 8 February 1920, Winston Churchill, then the Secretary for War, told readers of the Illustrated Sunday Herald about “Trotsky ... [and] ... his schemes of a world-wide communistic state under Jewish dominationâ€.
"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. It is certainly a very great one; it probably outweighs all others. With the notable exception of Lenin, the majority of the leading figures are Jews."
That's why Britain supported the Zionist scheme. They thought rightly that the unbearable condition of the Jewish status in Europe was leading them to change the civil order. And to all the revolutionaries parties in the world.
Churchill wrote on Bolshvism vs. Zionism “the fury with which Trotsky has attacked the Zionists generally, and Dr Weizmann in particular. The struggle which is now beginning between the Zionist and Bolshevik Jews is little less than a struggle for the soul of the Jewish people.â€
