Some governments in Central America and the Caribbean were hostile to Árbenz and the Guatemalan Revolution. Anastasio Somoza García, Rafael Leonidas Trujillo and Marcos Pérez Jiménez, the US-backed right-wing dictators of Nicaragua, the Dominican Republic and Venezuela, respectively, felt threatened by Arévalo's reforms. Under Arévalo, Guatemala had become a haven for pro-democracy activists from those three countries. Somoza, Trujillo, and Jiménez had supported Guatemalan exiles working to undermine the Guatemalan government, in addition to suppressing democratic popular movements in their own countries.
