"The socialist paradise didn't live up to his expectations. That shouldn't be a surprise. But it's got nothing to do with him being some kind of intelligence agent. "
Methinks that you've never been in the business - so let's try a little exercise in logic: if he was unenthusiastic about the joys of the Worker's Paradise, why would he bother writing a long and descriptive and sardonic account of his experiences? Who was he writing this story for? Saturday Evening Post? His wife Marina?
Why would he allegedly continue to support the Soviets after such disillusionment?
It's a Contact Report and a pretty good one.
Add that to how readily he got permission to regain his citizenship, got to bring the 'ol Soviet missus, and even plane fare and expenses home and you've got ask yourself how wonderfully lucky he really was.
Except, of course for when they shot him.
I'm not. The movie JFK depicted it as a film, because hey, it's a movie. But it was only a radio interview.
You make too many assumptions. But more importantly, it's not a logical argument. Just because something seems familiar to you doesn't overrule all the actual evidence.
