Brian Latell’s book: “Castro’s Secrets - Cuban Intelligence, The CIA, and the Assassination of John F. Kennedy” tells many details about the workings of the Cuban DIG and the events surrounding the assassination that I hadn’t seen before. He spells out a believable theory that has Castro knowing about LHO’s intentions to shoot JFK before it happened but remaining silent instead of warning the U.S. about it. An interesting book that, in my opinion, just might be true!
Let's see if I understand this correctly.
The premise of this is that Castro somehow knew in advance about the so-called insignificant "lone nut" Oswald's intention to kill Kennedy.
With that in mind, I would like to have explained, first of all, how Castro could have possibly known that? Was he physic or telepathic? Think about it, how would Oswald even get on Castro's radar? For Castro to know it in advance, there needs to have been some sort of contact and communication, either direct or indirectly, between Castro and Oswald, in which Oswald somehow announced his intentions.
Secondly, how in the world could Castro have known in advance that Oswald wanted to kill Kennedy, when Oswald, on the one hand, couldn't have known that Kennedy was coming to Dallas until it was announced, only a few days earlier, and, on the other hand, there is no known evidence that even remotely shows that Oswald intended to kill Kennedy at another location than Dallas.
It simply doesn't add up, unless of course the real premise is that Castro orchestrated the whole thing and simply used Oswald (and perhaps others at other locations) as a pawn in his own game. But that would make it an actual conspiracy and not a silent one....
