Two of his three wives are from former Eastern Bloc countries.
This is an ignorant statement and also incredibly xenophobic if advanced as an argument for Trump being pro-Soviet.
I can assure you that the Soviet Union got very little support from peoples connected to nations within the Soviet bloc, except for some Jewish families that brought proto-Bolshevik values with them. America got many Russian refugees hostile to Bolshevism.
Ferocious opposition to Communism is commonplace among Polish-Americans, the Slavic-Americans with which I have the most familiarity in view of living in a community that has many of them. If I lived in certain parts of Texas I would probably say the same of Czech-Americans, and if I lived in certain parts of Ohio I would say much the same about Hungarian-Americans (OK, they are not Slavs, but that is not the point).
The only Americans sympathetic to any officially-Marxist regime who have ethnic connections to a Commie state of the Cold War are Korean-Americans whom the People's Republic of China (PRC) has cultivated as allies. South Korea is a significant trading partner of the PRC, and Korean-Americans have plenty of commercial ties to the PRC. Korean-Americans might be delighted if the People's Liberation Army (of the PRC) liberates North Korea in response to something that a state grossly-undemocratic state best described as an absolute monarchy that in no way represents any part of the Korean people does something really stupid, like launching a missile at the United States over Chinese airspace.
If you know anything about the DPRK, it makes China look like a free country by contrast!
