When NewMexiKen visited Havana some years ago, American officials in a position to know told me their greatest fear was, that when Castro lost power, the exiles in Miami would think they were entitled to return and assume control. My sources were certain that the Cubans who had remained in Cuba and suffered through decades of repression and deprivation would not lightly surrender power and property to those who had left, most nearly 50 years ago.
Civil war was, they feared, the likely outcome.
The New Yorker had an excellent article last week about whether the revolution could outlive its leader, Castro’s Last Battle.
