"Yes, I am aware of Hoover's assessment. But in the end, Golitsyn's predictions proved correct, whereas the defectors Hoover's relied on proved to be phony."
So some argue. I would argue differently. In any case, part of my point is that because of this type of issue, it's unadvisable to rely too heavily on defectors' claims. I prefer to start with data that can be established independently of what defectors allege. The whole subject you're broaching can be studied productively independently of the Golitsyn controversy.
"I prefer to start with data that can be established independently of what defectors allege."
Golitsyn let it all hang out when he made those predictions. They were designed to be independently verified. That's why Riebling researched them. His conclusion? 94% of Golitsyn's predictions came to pass (whereas, every other Soviet analyst was completely taken by surprise). Indeed, his prediction about the effect this would have on the EU, NATO and the US are unfolding before our very eyes.
Did you read Golitsyn's books for yourself? If not, the summary of Golitsyn's predictions and analysis I posted above is a good place to start.
