It's a 'conservative' position to believe that Oswald didn't kill JFK, and that ultraliberal Lyndon Baines Johnson (the single worst president we've ever had, IMHO) would try to cover it up?
Okkkkkkk.....
Stone's position was that JFK never intended to go into Vietnam and that the 'military-industrial complex' gunned down Kennedy.
Oswald did assassinate President Kennedy, and all by his Castro-loving lonesome. Only doctrinaire leftists, and kooky John Birch types, assert otherwise.
But continue embarrassing yourself...
