Yeah I kow Trujillo was dead by then... Why get rid of him to put his right hand man (Balaguer) into power?
in a nutshell, he had become a nuisance. he forced us sugar businesses to sell their property to him under value, killed a us citizen in an attempt to cover up the kidnapping and eventual killing of a dissident on us soil, had repeatedly tried to kill romulo betancourt whom he personally dispised, ****ed of the catholic church, ruined the dominican economy by spending way too much money on the celebrations of his 25 years in power, killed and tortured more and more of his citizens in an attempt to reeastablish his grip on power and thereby, lost the support of a large part of the dominican elite, whose sons and daughters he had put in jail for conspiring against him.
it was felt in washington that he had gone a bit cookoo in the head and that he had become immune to advice. furthermore, the us feared that sooner or later, he would be overthrown, so it was better to control the coup rather than do nothing and run the risk of a "second cuba".
still, the us was pretty undecided, thats why they only delivered a couple of old rifles to his assassins, and provided no other support. when left leaning juan bosch was elected, washingtons worst fears appeared to become reality, and thus, he was quickly deposed and balaguer was put in his place.
