"And what do you mean by the U.S. recognized Soviet genocide "only in 1987"? "
My bad - it was only in 1988 did the US recognize the Russian genocide in Ukraine - something Russia still denies.

"That documentation refers to books and articles about Soviet oppression and violations of human rights and murders and gulags, etc. starting with reports"
You apparently are unaware of the difference between murder and "genocide".
You're dreaming if you thing Holdomor denial is not a big problem.

Interesting that you have now changed the subject from a generic discussion of "Soviet genocide" to your link to a specific instance (i.e. Ukraine). Apparently, you have difficulty with precision in your use of the English language.
However, as even your own link shows with respect to Ukraine, there was evidence presented BEFORE 1988 re: the Ukranian genocide.
With respect to your comment that I don't understand the difference between "murder" vs "genocide"
MURDER:
noun: unlawful premeditated killing of a human being by a human being
GENOCIDE:
noun: systematic killing of a racial or cultural group
United States scholars, researchers, and politicians recognized Soviet GENOCIDE years and decades before 1988 -- so stop playing stupid word games or semantic parsing of terms.
I suggest you review some of the following documents for evidence and discussion about Soviet genocide.
I'm only listing a representative sample merely to indicate how absurd your comments thus far have been.
I won't even get into all of the anti-Communist organizations that published articles and booklets pertaining to Soviet genocide and murder and oppression -- but suffice it to say that such organizations have existed since the 1920's throughout the non-Communist world. In our country, for example, there were groups such as American Coalition of Patriotic Societies (founded in the 1920's) and The Council Against Communist Aggression founded in February 1951 headed by Arthur McDowell.
I also will not bother to list the scores of Congressional hearings and reports which dealt, in one way or another, with Soviet violations of human rights and mass murder, etc.
I will not respond further to your nonsense because you obviously have never done even the most cursory investigation into this subject matter.
