(CORAL GABLES, Fla.) — The Trump administration on Wednesday intensified its crackdown on Cuba, Nicaragua and Venezuela, rolling back Obama administration policy and announcing new restrictions and sanctions against the three countries whose leaders national security adviser John Bolton dubbed the “three stooges of socialism.” “The troika of tyranny — Cuba, Venezuela and Nicaragua — is beginning to crumble,” Bolton said in a hard-hitting speech near Miami on the 58th anniversary of the United States’ failed Bay of Pigs invasion of the island, an attempt to overthrow the Cuban government. The measures seem likely to hit hardest in Cuba, which is at a moment of severe economic weakness as it struggles to find cash to import basic food and other supplies following a drop in aid from Venezuela and a string of bad years in other key economic sectors. Bolton announced a new cap on the amount of money that families in the United States can send their relatives in Cuba.
