I see it differently;
I'm amazed that kennedy did so MUCH damage in that little time.
FDR received total support and cover for his actions from the media; during a war. There is some justification for that.
kennedy turned the media into his personal cheering section, his death imbued the press with some kind of mystic need to make him holy; its still possible to end up in a fight should you suggest otherwise.
Every left wing nut case since then has had the benefit of that coup within the journalistic caste.
On top of that, the bureaucratic weasels who still infest State Department, schools, courtrooms, unions, and most local governments will each and every one cite the glories of JFK as their motive for action.
Carter benefited from kennedy's aura and what literally no one ever points out is that the two were virtually 90 degrees opposite in their policies.
You're right. I stand corrected.
