The only thing worse than those navy clowns running a land war is for the army clowns running a naval war. God, when I think about the war of 1815 I cringe. It's like, they just don't get it.
Kennedy's knifefighter instincts were perfectly suitable to running a PT boat, and he no doubt would have made a wonderfull privateer captain, but if you want to fight a land war in Asia you have to understand farmers.
At West Point from about 1880, among the first 100 Commandmants the first three are:
1. Do not become involved in a land war on the Asian land mass.
2. Do not become involved in a land war on the Asian land mass.
3. Do not become involved in a land war on the Asian land mass.

IMO JFK was an ignorant and arrogant a-hole who tried (egged on by little brother Bobby) to kill Castro at least six times, enthusistically did the dumbest things imaginable, damn near got us into World War III through really stupid mistakes, bungled the Bay of Pigs Invasion bigtime, was the only U.S. president ever to use full-time the services of a high-class pimp, and was so addicted to drugs that he had a hard time reading his speeches.

His image and the whole Camelot thing was a total fantasy created by spin doctors and fawning journalists. IMO he bears most of the problem for us getting inot the Vietnam fiasco.

God rot his soul in hell.

He got in Marilyn's pants.  Couldn't be all bad.  Had a sense of humor too.  And he was Irish.
