Just as the title suggests, I pose the question of how would the United States and the Kennedy family as a whole differ from OTL if the eldest Kennedy brother, Joe Jr., was not killed in action during WW2. Prior to his death, he was the one being groomed for the Presidency, not Jack, so I would imagine it would have some profound effects on the trajectory of the family’s political destiny.
To reiterate, how would Joe Kennedy’s survival in WW2 effect the Kennedy family, and/or the nation as a whole?
