I remember a story by the Reader's Digest which tied Oswald's activities as a Marine in Japan (IIORC) with the shooting down of Francis Gary Powers UT over Russia.
The Left has cunningly tried to finesse away Oswald's obvious commie connections by saying he was a CIA double agent. I don't buy that.
It has always been incredible to me that this bullshiite is so easily sold and bought. It's as if "Gee, did you hear Lee moved to Cincinnati and got job in a radio factory? Yeah, it's true. Great job. Got a fabulous apartment. Met a nice girl. Yeah, Her stepdad is a biggie with the State Police. Imagine that!"
Simple fact: No one in those days, that is no one, went into the USSR without 24/7 KGB coverage. Period. The fact that LHO had something to do with radar on the U2 flights out of Atsugi means that he would have been far and away above "normal" interest to the KGB. Just like, BTW, Bill Clinton, who has never explained his year in the USSR and the Eastern Bloc satellites. What exactly was he doing in Prague in The Spring of '68 ... after leaving Oxford in a hurry under a rape scandal?
