Actually it doesn't or perhaps your initial speculation was wrong or not what you meant.
Your initial comment was about getting rid of him to go to war.
If their goal was to go to war there is no reason to believe JFK was standing in their way. There is too much contrary evidence to suggest he was not exactly opposed to fighting the red menace not to mention there were simpler ways of accomplishing the same thing.
If you are now changing your argument to suggest he was kicking people out of their jobs and thats why he was assassinated I don't have an immediate comment.
What I would likely do is look at the counter-arguments to whatever you are presenting which undoubtedly exist and favor the one which seems most plausible.
A single documentary unless presented by people I know to have a strong history of credibility is unlikely to seal anything for me though even if I found the theories plausible.
