I've just finished reading Seymour Hersh's very interesting book The Dark Side of Camelot. He argues that the Bay of Pigs invasion went wrong in part because Castro was supposed to be killed by the time it started. When that didn't happen, the whole shebang began unraveling.
I wish I had read the book before I wrote about Maxwell Taylor in my own book The Generals. Hersh confirms my view that Taylor was a snake, and that the Kennedys (John and Robert) were taken in by him -- and that is one of the reasons we wound up in Vietnam, as they all showed each other how tough they were, and Taylor thought he had found a role for the Army in a nuclear world.
