Nuclear Issues

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

Joseph S. Nye writes that evaluating ethics in international relations is difficult, and Kissinger's legacy is particularly complex. Over his long tenure in government, he had many great successes, including with China and the Soviet Union and the Middle East. Kissinger also had major failures, including in how the Vietnam War ended. But on net, his legacy is positive. In a world haunted by the specter of nuclear war, his decisions made the international order more stable and safer.

What sounded so simple during last year’s presidential campaign has turned out, like everything related to Iran, to be quite complicated.

"This week, with little fanfare, one of the world’s key restraints on the spread of nuclear weapons came under scrutiny, as a month-long review of the Non-Proliferation Treaty (NPT) concluded at the United Nations," writes Graham Allison. "Negotiated over the 1960s, the NPT was signed in 1968 and became international law in 1970. As specified by the treaty, members hold a conference every five years to assess the agreement. The exercise offers insight into our nuclear age, and perspective ahead of the coming debate over a treaty to constrain Iran’s nuclear ambitions."
