Despite the righteous platitudes of the American and French Revolutions, the idea of an independent Black Republic created through force of arms did not sit well with the powers that be in the Capitols of Europe and America. There was virtually universal agreement among the European/White leaders of the time, including President Thomas Jefferson, that the example of Haiti was a threat to their national interests - profiting from the slave trade and/or colonialism in Africa, the Caribbean, Central and South America. Therefore, it was imperative that Haiti be isolated, marginalized and rendered weak as a "Black nation." Under threat of a new invasion, Haiti succumbed to demands from France to pay millions of dollars in reparations for title loss of property (enslaved Africans and the plantations) incurred during the Revolution. The burden of this debt would cripple Haiti's struggle for development well into the 20th century. In 1915 the U.S. invaded and occupied Haiti until 1934, and has treated Haiti as a neo-colony ever sense.
Since 1959, when Fidel Castro overturned the corrupt, proAmerican government of Fulgencio Batista and declared Cuba a communist nation, the American policy has been one of not just opposing the Cuban government, but of isolating Cuba and its citizens from all economic and social interaction with the United States. The reality is that allowing trade and travel does not eliminate our ability to address Cuba's human rights problems. In fact, one could argue - as even some conservatives did when we participated in the 2008 Olympics in Beijing - that such interaction gives greater voice to questions of human rights in Cuba. Our policy against Cuba has largely been shaped by the politics of Florida, where anti-Castro Cuban immigrants have long been a powerful economic and political force. But even that is changing; younger Americans of Cuban origin are becoming increasingly more likely to support travel to, and trade with, Cuba.
