Six Crises is the first book written by Richard Nixon, who later became the 37th president of the United States. It was published in 1962, and it recounts his role in six major political situations. Nixon wrote the book in response to John F. Kennedy's Pulitzer Prize–winning Profiles in Courage, which had greatly improved Kennedy's public image.

On May 13, 1958, US Vice President Richard Nixon's motorcade was attacked by a mob in Caracas, Venezuela, during Nixon's goodwill tour of South America. The event was described at the time as the "most violent attack ever perpetrated on a high American official while on foreign soil." Close to being killed while a couple of his aides were injured in the melee, Nixon ended up unharmed and his entourage managed to reach the U.S. embassy. The visit took place only months after the overthrow in January of Venezuelan dictator Marcos Pérez Jiménez, who in 1954 had been awarded the Legion of Merit and was later granted asylum by the United States, and the incident may have been orchestrated by the Communist Party of Venezuela. U.S. Navy Admiral Arleigh Burke mobilized fleet and Marine units to the region, compelling the Venezuelan government to provide full protection to Nixon for the remainder of the trip.
