Let me expose some knowns that contradict some of the basic reasons why the event took place based upon your post above...
Trujillo was a dictator that used terror and a well-oiled repression machinery in the form of the National Police, Armed forces, State institutions and private citizens in covert operations.
The idea that any person would commit to planning, discussing or meeting any foreign or national entity or person due to the issues that you marked as factors to the demise of Trujillo, is not feasible from that stand point.
You have to understand that Trujillo did kill any person that was suspected of plotting against his ruling/person right after his goons tortured the person to obtain information to the extend of associates believed to be involved, along with the immediate extension of his family when given the chance that such members could become further involved after their sibling?s demise.
No person that wasn't closely related or under a direct and insurmountable death sentence by his regime, would have acted in the manner that you describe above for the reasons that made it a must to eliminate the man.
The attempt by Trujillo's order on Venezuela's Betancourt, Galindez kidnapping and killing, the economic situation of the people in the DR were not any motive for a private person to join in the plot to kill the Chivo.
If you do investigate some more into the private lives of the persons that were involved in his killing, you'll find that most were already in the line to be victims of his machinery one way or another.
The military members of the plot were subjects of repeated purges and torture just like any civilian and with more chances of it too.
The civilians were not immune of the limbs of this regimen; neither were their immediate next of kin.
The plot against Trujillo was born out of the self preservation will that makes a person face imminent death to either be free from the threat or die fighting, unlike most victims ever have a chance to.
One must fill these shoes to understand the weight that was put on their shoulders, should the plot fail miserably. They had to take under account that their own circle of family and close friends were going to be a target of the homicidal machinery once their identity was known.
The only thing that they never planned for or failed to prepare for, was that the aftermath of their success on their plot would create a national manhunt and no place was going to be safe for them once the first shot was fired.
But, it's history that shows that desperate people don't plan for tomorrow when their "today" is sure to be their last.
The US had allowed a regimen to evolve right under their nose in the Caribbean. One that was proving to be a hot potato to handle unlike Cuba politically and in the local public opinion. Trujillo had made the SIM kin to the CIA covert operations that were proved by his longevity and untouchable stance for so long after his fall from grace in the US.
Let's just say that the US President had a daily report of the world status every morning in the white house, Trujillo had the "YouTube" of today with the "CNN" to back it up with.
Trujillo's demise was not the result of any event that was happening to the people of the DR or US, Venezuela, Cuba or else. It was the culminating point of decades of criminal and despotic ruling over a vastly poor and uneducated people that feared their children future more than his present reign of terror at the time.
When Amiama Tio was asked why they did it, he had this to say: It had to be done, he had to be put down! So it was also echoed by Barrera.
