The international debate about nuclear risk has catalogued many different kinds of risk and danger. But two stand out as especially salient: the risk of the nuclear arms race and the risk of employment of nuclear weapons arising out of a conventional conflict. The five nuclear weapon states (NWS) have a special responsibility to contain these risks. They also have a responsibility to try to manage the risk posed by nuclear proliferation. Constructive action by the five is both necessary and possible. But they face many challenges to such action, including the limits on their ability to cooperate given their wariness of each other.

This essay explores four areas to focus improved NWS cooperation to reduce nuclear risk. These include efforts to:

  1. Prevent decoupling of NWS nuclear policy communities

  2. Frame principles for cooperative nuclear risk reduction

  3. Address areas of concern about future strategic military balances

  4. Elevate and deepen existing dialogues

    Lukashenko’s Concessions to Kyiv Reflect Russia’s Weakness

    The recent damage inflicted by Ukrainian drones and missiles on Russia has made Belarus aware of its own vulnerabilities—and surprisingly amenable to Kyiv’s demands.

    Could Ukraine Succeed in Torpedoing Putin’s Approval Ratings?

    It is not a phenomenon unique to Russia that the public of a country at war (even the aggressor) enduring airstrikes will not overturn its government but rather show solidarity with it and blame its woes on the enemy.

    Belarus Is a Test Case for Ukraine’s New Role in the Region

    Ukraine’s increasingly confrontational posture on Belarus reflects Kyiv’s effort to shape the emerging regional order in Eastern Europe. Kyiv wants to limit European normalization with Minsk—and any future rapprochement with Russia.
