Best motives

[Steve M. Galbraith]

Well, since we're splitting hairs, I said "the Kennedys appear to have been interested" which is not a claim that I knew for sure. Plausible deniability keeps us from knowing the full extent. The Castro assassination plots were confined to a select few within the White House Special Group (SG-A) and the CIA, along with liason Lansdale at Defense. RFK chaired the SG-A but I believe he was also briefed in his AG office.

There are some who suspect President Kennedy knew in advance of the assassinations of Rafael Trujillo and President Diem.

The "Cuban Project" was also known as Operation Mongoose. It was run by Air Force Major General Edward Lansdale from the Defense Department, with assistance from William King Harvey at the CIA.

    "The Cuban Project played a significant role in the events leading up to the
     Cuban Missile Crisis of 1962. The Project's six-phase schedule was presented
     by Edward Lansdale on February 20, 1962; it was overseen by Attorney
     General Robert Kennedy. President Kennedy was briefed on the operation's
     guidelines on March 16, 1962. Lansdale outlined the coordinated program of
     political, psychological, military, sabotage, and intelligence operations as well
     as assassination attempts on key political leaders."

You were seemingly implying - I can't read your mind - that the Kennedys were interested in killing numerous foreign leaders. As in multiple figures. In fact, the evidence I've seen is that they were "interested" in just one: Castro. And more than just "interested". I think they were quite aware of the plots and implicitly if not explicitly approved of them.

As to Diem and Trujillo: Again, where's the evidence? Didn't Lodge offer Diem and his brother protection in the US Embassy? And they rejected it? I don't think there's any evidence that JFK approved of or signed of on their murder. Same with Trujillo. No US government involvement.

As to the Wikipedia quote: there's no source for the claim that Mongoose also involved the assassination plots against Castro. Again, my understanding is that those plots were organized and run under a more secret program or programs. Mongoose was pretty well documented - there's a long paper trail - and I find it hard to believe that the Castro plots would have been part of it.

from The Forty Committee, By L. Fletcher Prouty

"By God, Prouty, those bastards are going to let them murder Trujillo. They go around telling everyone this spombleprofglidnoctobuns about anticommunism; invading Cuba with a half-assed task force and then when they have one tough son-of-a-As I was walking a' alane, I heard twa corbies makin' a mane. The tane untae the tither did say, Whaur sail we gang and dine the day, O. Whaur sail we gang and dine the day?  It's in ahint yon auld fail dyke I wot there lies a new slain knight; And naebody kens that he lies there But his hawk and his hound, and his lady fair, O. But his hawk and his hound, and his lady fair.  His hound is to the hunting gane His hawk to fetch the wild-fowl hame, His lady ta'en anither mate, So we may mak' our dinner swate, O. So we may mak' our dinner swate.  Ye'll sit on his white hause-bane, And I'll pike oot his bonny blue e'en Wi' ae lock o' his gowden hair We'll theek oor nest when it grows bare, O. We'll theek oor nest when it grows bare.  There's mony a ane for him maks mane But nane sail ken whaur he is gane O'er his white banes when they are bare The wind sail blaw for evermair, O. The wind sail blaw for evermair.' right there in the heart of the Caribbean, what do they do? They take away his support. He'll be dead in less than forty-eight hours."
        General Darcy was spitting mad. He was one of the toughest guys who ever strapped himself into a P-51 fighter. He was a real professional. He believed in fighting the Cold War as hard as he had fought the total war against Hitler. Now, in May 1961, less than one month after the Bay of Pigs, he had just come back from a meeting of the Forty Committee (then called the Special Group 5412/2). They were playing God again and Rafael Trujillo, the dictatorial president of the Dominican Republic, was the next target for termination.
        "Prouty, before you go back to your shop, go down to personnel. Find out what it takes to retire. This is not my game. I'm getting out." Before Darcy's papers could be processed, Trujillo was dead, murdered in the city that carried his name, by men of his own army.
        Tom Darcy had made it clear many times that he had no love for Trujillo nor for what he stood; but despite that he knew Trujillo would never condone communism, and anyway, "it is not our business to mess around in their internal affairs."  Assassinations are not made by the Forty Committee; they are permitted.

I believe Prouty went on the record and admitted during his role of Chief of Clandestine Operations he participated logistically in Trujillo's assassination/overthrow. I think it was during one of the Stone JFK movie debates he alluded to Trujillo's death as being the result of a CIA backed operation. If I can find it I'll post the clip.

How many average Cuban Joe's were killed, or don't they count?
A rumoured 400 in one day(NOV8 1962), not enough?
Want to estimate how many were killed because we blocked food and medicine? Go right ahead.

The importance of PD mentioned in the very first sentence.
