The essential point was captured in John F. Kennedy's celebrated remark that while we would prefer decent democratic regimes, if the choice is between a Trujillo or a Castro, we will choose the Trujillo. It is necessary only to add three points: (1) the concept of "a Castro" is very broad, extending to anyone who raises problems for the "rich men dwelling at peace within their habitations," who are to rule the world according to Churchill's aphorism, while enjoying the benefits of its human and material resources; (2) the chosen "Trujillo," however monstrous, will be a "moderate" as long as he fulfills his function; (3) the "Trujillo" will make a quick transition from favored friend to another beast to be destroyed if he shows the bad judgement of stepping on our toes. This story has been reenacted time and time again, until today. Saddam Hussein is only the most recent example.
(Rafael Trujillo was dictator of the Dominican Republic (1938-1961))
