A long-term plan to "infiltrate" think tanks, eh?
That is not a project that requires years of effort and much expenditure. I think someone was scamming Moscow Center. "Yes, comrade, we are planning to infiltrate the think tanks in five or ten years. Meanwhile, please send funds for a new car."
I also suspect the FBI is hyping this one.
