Hi Jerry,
I seem to remember that Kennedy managed to "out-hawk" Nixon on Cuba before the election. This was of much concern to Nixon, after all the Cuba invasion etc were his, yet he was hamstrung at the time of the debates. I had thought it was the during the 4th debate, probably faulty memory.
Clearly the BOP operation and the CIA/Mafia based Castro assassination plots originated with Nixon. After all he was the "President-in-waiting". The blame for CIA/Mafia usually falls to Bissell, but such actions surely required at least WH approval.
Does any evidence exist that the incoming Pres was briefed and approved of the Castro plots?
