Before politician Fidel Castro became the hemispheric menace, total U.S. aid to Latin America was running under $500 million a year and Latin American statesmen spent much of their time bewailing the niggardliness of Uncle Sam. It was not that lie didn't have the money, but he was squandering it elsewhere. The complaint has some substance. If consistency is the hobgoblin of little mind; the U.S. correspondents in Moscow, Russia, as well as those who operate in Washington, D.C., must have minds of such power and greatness that they are really wasted in newspaper work. Now is the open season on speculation on what is going on behind the walls of the Kremlin, Moscow, Russia, and almost every correspondent has a theory based on information from sources lie dares not name, but which take his word for it, are of the most incontrovertible authority.
