Summary Report No.101: Where Next for the TPNW?

This is a summary report of an online meeting of experts and policymakers, convened by the Toda Peace Institute and the Norwegian Institute of International Affairs (NUPI), to discuss the way ahead for the TPNW. The discussion examined the role of nuclear allies, the scope for building a regime of verification measures around the TPNW, and whether the differences between TPNW supporters and nuclear weapons and umbrella states are best met by bridge building or by contentious engagement.The Treaty for the Prohibition of Nuclear Weapons entered into force on 22 January 2021. So far, the nuclear weapons states and the nuclear umbrella states have dismissed its significance, but there are signs of dissent in the chorus of rejection.
