JG: They got that one right! Until the U.S. Congress UNCONDITIONALLY lifts the Cuba embargo/blockade, no new embassies should be opened in La Habana or in Washington D.C. The IS (Interests Sections) should continue as usual, until the embargo is lifted. One man's opinion, mine!
Raul Castro should NOT BE too eager to please the Yankees, since Washington is the aggressor and Cuba is the aggrieved and damaged country. Reparations for the failed embargo? The Yankees failed to overthrow the Cuban government, which is what JFK intended.
