I think that it is a fair question to ask whether LHO (Hickey actually)(i think LHO's slug wasnt deadly) did us a favor.
What would the world be like if JFK lived?
Theusofa is based on having winners & loozers. The strong flourish, the weak die.
Well, that same system applies to countries.
Oswald praps wanted a usofa where there were no loozers (well, ok, one loozer).
But if theusofa dies then all are loozers.
Theusofa started with a lie, followed by the murder of natives, followed by war on Mexico.
Its a wonder that the sniper's nest wasnt crowded.
