Kenneth N. Waltz, a pre-eminent thinker on international relations who was known for his contrarian, debate-provoking ideas, not least his view that stability in the Middle East might be better served if Iran had a nuclear weapon, died on May 12 in Manhattan. He was 88.

The cause was complications from pneumonia, said Columbia University, where Mr. Waltz was a senior research scholar.
