Why didn’t they kick Oswald out of the USMC when he started speaking Russian and praising Castro and the USSR? This was 1958 and its the height of the Cold War and the USMC is willing to tolerate a commie sympathizer and trust him with throwing grenades and shooting auto rifles during the training period?
What about that photo of Oswald in the company of Alpha 66 members at some point during his training?
Then they sent the commie sympathizer kook to the top secret base in Japan where he could have access to codes and listen in on USSR radio traffic.
Then the U2 spy plane getting shot down , and Oswald gets his hardship discharge and then he defects to USSR and gets the job in Minsk.
And Marina Oswald who already previously had met the other defectors , (her uncle being a KGB officer ?) meets Oswald too, they get married , and then back to the USA no problem.
So JohnM could be right that Oswald was just a random kook, but these coincidences seem
to indicate Oswald was a CIA trained kook.
