Retaliation for the Bay of Pigs.

[21twelve]

In the Nixon tapes, right before the infamous gap, Nixon says something about how Watergate will bring up “the whole Cuban thing”.

I've come to believe Nixon was referring to his Cuban “plumbers” being involved (prior to Nixon using them) in the assassination. I think it was Haldeman that later wrote that he thought that was what Nixon was referring to as well.
