Since the 1940s, U.S. relations with Argentina have been tense, when the U.S. feared the regime of General Peron was too close to Nazi Germany. In 1954, American support for the 1954 Guatemalan coup d'état against the democratically elected President Jacobo Arbenz Guzmán fueled anti-Americanism in the region. This CIA-sponsored coup prompted a former president of that country, Juan José Arévalo to write a fable entitled "The Shark and the Sardines" (1961) in which a predatory shark (representing the United States) overawes the sardines of Latin America.
