It may seem like a stretch, but the Cold War crises that U.S. President John F. Kennedy faced hold important lessons for the nuclear impasse with Iran. Newly released historical files on the confrontations between the United States and the Soviet Union in the early 1960s can help us better understand what to expect if the current negotiations with Tehran fail and we are soon confronted with a nuclear-armed Iran.
Kennedy faced an unpredictable, risk-taking and at times aggressive opponent in Soviet leader Nikita Khrushchev. Yet he frustrated Khrushchev's ambitions and helped the U.S. avoid war through a combination of American nuclear superiority, firmness in defending national interests and a willingness to resist alarmist thinking.
The first observation from Kennedy's Cold War experience is that if you assume the worst, you may get the worst. If any one lesson emerges from the documents, memoirs and research published in recent years, it is that the U.S. and the Soviet Union wasted billions of dollars and rubles guarding against a surprise nuclear attack that neither country ever seriously contemplated launching. The obsession with this worst-case scenario made many crises far more dangerous than they needed to be — and even caused some of them.
