For a long time, the U.S. and the Dominican elite supported the Trujillo government. This support persisted despite the assassinations of political opposition, the massacre of Haitians, and Trujillo's plots against other countries. The U.S. believed Trujillo was the lesser of two or more evils. The U.S. finally broke with Trujillo in 1960, after Trujillo's agents attempted to assassinate the Venezuelan president, Rómulo Betancourt, a fierce critic of Trujillo. Trujillo had become expendable. Dissidents inside the Dominican Republic argued that assassination was the only certain way to remove Trujillo.
