That is a dangerous historical error. The Bolsheviks (Communists) never had anything to do with “overthrowing the Tsar”. Tsar Nicholas II abdicated in March 1917 because of general social turmoil, and there were free elections in April 1917, leading to the Provisional Government under Kerensky. While all this was happening, Lenin was still in Switzerland where he lived 1907 to 1917, Trotsky was still living in Brooklyn, NY, and hundreds of other agents were elsewhere in the world. They only streamed back with the help of the German government to overthrow the ELECTED GOVERNMENT in Russia in October 1917.
Even if that is true, it has little to do with my point - that Communist agents have been hard at work in this country long before the 1980's and that Julius Hammer was sent to this country to raise money and influence for the Communists. He started the Communists Party USA, First as the Workers Party USA. Arthur Sulzberger, Publisher of the NYT, and Al Gore, Sr. and later Al Gore Jr., were in Armand Hammer's pocket and were active in furthering the Marxist cause in the country going back to the early 1900s.
