What does this have to do with the unprecedented scale and cover up of the Communist Genocide of the 20th Century?
"Cover up of the Communist Genocide"> -- you've got to be kidding!
Entire books and doctoral dissertations have been written about it for decades. Many of the original reports of Soviet gulags and human rights abuses originated with emigres from the Soviet Union who were interviewed by Western scholars and intelligence agencies.
You obviously have not done even the most cursory examination of the historical record and just have some sort of agenda you want to promote.
See, for example:
"The Black Book of Communism: Crimes, Terror, Repression" originally published in Europe, then picked up by Harvard University Press in 1999. It was described in a New York Times review as:
"An 800-page compendium of the crimes of Communist regimes worldwide, recorded and analyzed in ghastly detail by a team of scholars. The "notes" section of the book consists of 62 pages of bibliographic citations to substantiate the assertions made in the book. This documentation relies upon previous scholarly works from the 1920's forward. So much for your falsehood about a "coverup".
