Restrictive U.S. policies toward Cuba are ineffective, have failed to achieve their stated purpose of promoting democracy and should be reevaluated to take advantage of recent political changes on the island, according to the senior Republican on the Senate Foreign Relations Committee. The views of Sen. Richard G. Lugar (R-Ind.) are appended to a report by minority committee staffers that calls for lifting Bush administration restrictions on travel and remittances to Cuba, reinstituting formal bilateral cooperation on drug interdiction and migration, and allowing Cuba to buy U.S. agricultural products on credit. Scheduled for release Monday, the report stops short of proposing that the 47-year-old U.S. trade embargo against Cuba be lifted.
