中美共同防禦條約
In 1979, when President Carter normalized relations with Communist China, Goldwater and some other Senators sued him in the Supreme Court, arguing that the President could not terminate the Sino-American Mutual Defense Treaty with Republic of China (Taiwan) without the approval of Congress. The case, "Goldwater v. Carter" 444 U.S. 996, was dismissed by the court as a political question.
