There's the reason for maintaining the embargo: Jimmy Carter, the foreign policy FAILURE, tyrant appeaser, and numero uno hater of America!
Yes, Jimmy Carter hates America for voting him out of office. He's a bitter and spiteful little man, whom the press adores primarily for his left-wing views, and not for his 'habitat for humanity.'
Carter has many people fooled, but not me. He may be a USNA graduate, but he didn't learn a damn thing.
