Scott Sagan, in this piece for Foreign Policy, remembers his longtime friend and colleague Kenneth Waltz. Waltz passed away on May 13. Sagan praised his work, noting that the realist perspective on the stabilizing effects of nuclear weapons struck a chord with international experts and strategists, even though his views were not popular in the United States. Waltz's contributions to the debate about nuclear weapons have left an enguring legacy.
