After Robert Kennedy was assassinated in 1968, Jackie took Caroline and John Jr. out of the United States, saying: "If they're killing Kennedys, then my children are targets ... I want to get out of this country." The same year, she married Greek shipping tycoon Aristotle Onassis, and the family went to live on his private island of Skorpios. Kennedy is said to have considered his stepfather "a joke". When Onassis died in 1975, he left Kennedy $25,000, though Jacqueline was able to renegotiate the will and acquired $20 million for herself and her children.
