Nuclear Issues

This week in Say More, Project Syndicate talks with Joseph S. Nye, Jr., an emeritus professor at Harvard Kennedy School, a former U.S. assistant secretary of defense, and the author, most recently, of A Life in the American Century.

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

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

Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

In this Q&A, Joseph S. Nye talks about his advice for the interim and future president of Harvard in the wake of Claudine Gay's resignation, which countries should be highest on our radar to prevent the threat of nuclear war, what role the U.S. should play in the Russia-Ukraine war, the significance of U.S. alliances in the Middle East, and more.

At a moment when arms control is deeply troubled and may be dying, two eminent scholars, Marc Trachtenberg and the late Robert Jervis, have taken a fresh look at the beginnings of strategic arms control fifty years after the signing in Moscow of the SALT I agreements in May of 1972. They do so from different vantage points, writes Steven E. Miller.

This year's G7 summit in Hiroshima sees nuclear disarmament and non-proliferation sitting high on the agenda, amid rising tensions between the nuclear states and an increasingly divided international order.  Six contributors offer their analyses, including the Belfer Center's Mayumi Fukushima.

States frequently acquire proof that other states have violated norms. Yet, existing theories do not fully explain how states wield such proof to coerce wrongdoers. Four case studies of nuclear proliferation probe a novel theory of how states coerce norm violators by concealing, sharing privately, or publicizing proof of guilt.

Wedge strategy theory explains how states use strategic arms control to divide adversaries by affecting their trust, threat perceptions, and beliefs about a commitment’s trade-offs. Examining three landmark arms control negotiations shows how the wedge motive was a key component to these negotiations.

Abolghasem Bayyenat and Sayed Hossein Mousavian advise the United States and Iran to aim for reaching a modus vivendi that keeps their political conflict within manageable limits. Otherwise, another round of dangerous mutual escalation in the illusory hope of building leverage and extracting more concessions from each other is inevitable.
