FILE - In this Feb. 22, 2012 file photo, a mural featuring Venezuela's President Hugo Chavez, left, and Cuba's Fidel Castro, adorns a wall in Caracas, Venezuela. Under Chavez’s leadership, Venezuela has sent billions of dollars a year to Cuba through trade and petro-aid, supplying about half of the island’s energy needs at greatly subsidized rates. The Venezuelan president regularly calls Fidel Castro his ideological father and has followed much of the Communist legend’s governance and foreign relations playbook.
