Well conspiracy advocates say Bush, Sr. was involved in the Bay of pigs - that he provided the ships for the invasion one named "Barbara" I forget the name of the other ship.
"conspiracy advocates" say a lot of things, particularly regarding the Bush family; before that, about Nixon/Kissinger. David Ickes has a lot of frankly ridiculous things to say about Jimmy Carter, the Bush family, Ronald Reagan, and a host of others. There is nothing much to any of it, and in the case of this Cuban propaganda organ, there's nothing to recommend it.
