Experts discuss arms control in the current geopolitical environment.

The Doomsday Clock stands at 90 seconds to midnight – the closest to global catastrophe it has ever been. As geopolitical competition intensifies, nuclear risks are resurging at an alarming rate. The collapse of key arms control agreements, such as the Intermediate-Range Nuclear Forces (INF) Treaty, has removed crucial safeguards against arms races. Efforts to extend or replace existing treaties face significant hurdles in the current geopolitical climate.

Nuclear rhetoric has become more aggressive, as evidenced by Russian and North Korean nuclear threats. Several nuclear-armed states are also engaging in extensive modernization programmes of their nuclear arsenals, potentially fuelling a new arms race.

Despite these pressures, the number of nuclear possessor states has held steady so far. The ongoing Iranian efforts to build nuclear weapons is the closest attempt by a new state to acquire nuclear weapons. As the global security environment becomes more and more tense, existing nuclear possessor states increasingly rely on their nuclear weapons. This might threaten the global consensus against nuclear proliferation.

This session examines these competing pressures and propose strategies to reduce the risks of nuclear weapons use and proliferation. Our expert panel explores diplomatic initiatives, technical measures, and policy innovations to address these critical challenges.

This expert panel discusses key questions including:

  • Are we already in the middle of a global nuclear arms race?
  • How can international arms control treaties be negotiated in the current geopolitical environment?
  • Does a new US president change the nuclear calculus? Is the US still able to reassure allies of its ‘extended deterrence’?
  • How can we reduce the risk of additional proliferation? Which states might want to acquire nuclear weapons and what can we do about it?

The institute occupies a position of respect and trust, and is committed to fostering inclusive dialogue at all events. Event attendees are expected to uphold this by adhering to our code of conduct.
