I haven’t looked into those areas yet. This line of thinking was not the original intent of my research. Hopefully if the stars align, I’ll be headed back to school this fall and devote more brain cells to this issue.

You are correct, though. These are politically charged issues so it is a challenge to get to the facts. I attempted to pull some information from the GW Cold War Research Center on Soviet Influence in the US counterculture movement and I got zero support. I can't read Russian so I was out of luck.
