What the OP is describing is a pretty popular historical counterfactual. There've been a lot of books and articles theorizing about what would have happened in certain historical events if JFK had been president instead of Johnson or Nixon. So saying "nobody cares" is plain wrong.
Conterfactuals can be a very interesting way of posing new questions or theorizing around the motivations of players in certain events, but they can never give firm answers, much like all historical analysis.

now i study history and my teacher says "never do what if history"
because you say what if.... that creates 20 other what ifs and they create 100 other what ifs and so on.
That's what makes thorough what if scenarios interesting, not because of their effect on one event, but because of their immense possible ripple-effect on all events tied to that event and every event leading up to or following that one event. But yeah, it might be a bit much for a forum thread.
