Talk about theories!...You come up with a brand new one every day
Wouldn't just shooting the president have been the next bet?
Fritz was the one of the last people to spend considerable time with Oswald.
Mr. DULLES. Have you any views of your own as to motive from your talks with him? Did you get any clues as to possible motive in assassinating the President?
Mr. FRITZ. I can only tell you what little I know now. I am sure that we have people in Washington here that can tell far more than I can.
Mr. DULLES. Well, you saw the man and the others didn't see the man.
Mr. FRITZ. I got the impression, I got the impression that he was doing it because of his feeling about the Castro revolution, and I think that he felt, he had a lot of feeling about that revolution.
(At this point the Chief Justice entered the hearing room.)
Mr. FRITZ. I think that was the reason. I noticed another thing. I noticed a little before when Walker was shot, he had come out with some statements about Castro and about Cuba and a lot of things and if you will remember the President had some stories a few weeks before his death about Cuba and about Castro and some things, and I wondered if that didn't have some bearing. I have no way of knowing that other than just watching him and talking to him. I think it was his feeling about his belief in being a Marxist, I think he had--he told me he had debated in New Orleans, and that he tried to get converts to this Fair Play for Cuba organization, so I think that was his motive. I think he was doing it because of that.Oswald in New Orleans handing out "Hands off Cuba" leaflets

Oswald's "Fair play for Cuba" membership card where he was also the Chapter President.

Three days before Oswald killed Kennedy, there was this newspaper article in the Dallas Times Herald of Kennedy saying that it would be a happy day if the Castro government was ousted.

Oswald's personal possessions had a number of positive Castro literature.

A week after the Dallas Herald Times reported that Walker wanted to "liquidate the [communist] scourge that has descended upon the island of Cuba" Oswald ordered his rifle and not long after Oswald took photos of General Walkers house and a little later Oswald tried to kill General Walker.
In February 1963, Walker joined Billy Hargis on an anti-communist tour named "Operation Midnight Ride".[24] In a speech Walker made on March 5, reported in the Dallas Times Herald, he called on the United States military to "liquidate the [communist] scourge that has descended upon the island of Cuba."[25] Seven days later, Lee Harvey Oswald ordered a Carcano rifle by mail, using the alias "A. Hidell".[26]https://en.wikipedia.org/wiki/Edwin_Walker
