"The Shah became one of America’s most trusted Cold War allies, and U.S. economic and military aid poured into Iran during the 1950s, 1960s, and 1970s. In 1978, however, anti-Shah and anti-American protests broke out in Iran and the Shah was toppled from power in 1979. Angry militants seized the U.S. embassy and held the American staff hostage until January 1981. Nationalism, not communism, proved to be the most serious threat to U.S. power in Iran."
