“Oswald writes a fairly coherent report of his time in the Soviet Union with lots of critical detail of the Soviet system, yet he’s a “committed Marxist”.”
And also Oswald the committed communist Cuba supporter decides to shoot Kennedy, who was under deep criticism for not going to war with Cuba, and for the thaw going on with Kruschev.
So Oswald the Communist decides to shoot someone under deep criticism for being soft on Communism.
On the other hand the murder sure did benefit the CIA and Joint Chiefs agenda, and also the mob agenda who lost Cuba and was under attack by Bobby.
To solve this, just look at who benefited.
I have my opinion, but like all of you, it is based on incomplete facts.
