Was John Kennedy courageous

Answer 1

Not especially.

His reputation for heroism in the Pacific was manufactured by his father, who had a lot of influence in Hollywood and made a Propaganda film about him that magnified a very small incident into a major combat achievement. Significantly the medal he got was at the lowest level, more-or-less equivalent to a school life-saving medal.
