In Inevitable Revolutions: The United States in Central America (2nd edition, 1993), Walter LeFeber analyzes the extraordinary continuity of U.S. policy in Central America. Indeed, from the Rio Bravo all the way to Tierra del Fuego, for more than a century, the United States has refused to tolerate leftist governments when recourse to other options has been available. Thus even in 1959, it didn't take a political scientist to predict that the United States would not accept the Cuban revolution.
