The Bush administration is defying calls to lift its embargo on Cuba following the announcement of Fidel Castro’s resignation. On Tuesday, more than a hundred members of Congress urged the United States to review its policy of isolation toward Cuba. The letter stated, “Our policy leaves us without influence at this critical moment, and this serves neither the U.S. national interest nor average Cubans, the intended beneficiaries of our policy.” The U.S. has maintained an embargo on Cuba since 1960.
