LBJ may or may not have sympathized with fascism, but in this case he was only complicit in the Big Event. He obviously made some sort of deal to allow it to happen and had no intentions of starting WW3, which was the whole point of Oswald being portrayed as a lone nut. LBJ was probably responsible for preventing another Cuban Missile Crisis. Since JFK didn't bite on WW3, LBJ was next in line to carpe diem. Phew, another narrow escape from Armagedon. No wonder LBJ never appointed a VP. He also made an extra effort to make up for his sin of complicity. You realize he went mad in the end, right?
These fascists who essentially ran the government - or had great influence in it - allowed LBJ to do all of this? They killed JFK to stop him and his liberal policies but then let LBJ do the very things and more that they killed Kennedy for doing or trying to do? You have all of these powerful groups doing all sort of things to stop JFK and then have them powerless to stop LBJ? I would suggest that if LBJ was not one of these fascist murderers he would certainly know they were around? And he still enacted many of JFK's policies? The ones that led to the fascists killing him?
Why did they let LBJ end the covert war on Cuba? Or not push for it (since it was the Kennedys who were behind it anyway). Isn't that, in part, why they killed JFK? He was reaching out to Castro?
None of this, I hope you realize, makes a lick of sense? You have fascists in control, they killed JFK because he was too liberal, and then LBJ comes in and is even more liberal than JFK. That's kind of a dumb theory, don't you think?
