Given the treaty is steadily becoming a part of international nuclear nonproliferation and disarmament architecture, it is imperative for the United States, nuclear-armed states and states under the U.S. nuclear extended deterrence “umbrella” to consider how they can also productively engage with the treaty and its states parties,

On the afternoon of the first day of December 2023, the UN conference room in New York was filled with long and powerful applause, when the state parties to the Treaty on the Prohibition of Nuclear Weapons (TPNW), known informally as the “nuclear ban treaty,” concluded the second meeting on implementation since it entered into force in January 2021.
It has been just five years since the treaty was concluded in 2017, but the TPNW is already helping to bolster the international nuclear nonproliferation and disarmament architecture by reinforcing the norms against nuclear weapons use and providing a path for non-nuclear weapon states and communities and populations adversely affected by nuclear weapons to engage in efforts to advance disarmament and address the damage done by past nuclear weapons testing and use.
Since the TPNW opened for signature, the number of states parties has grown to 70. Significantly, the number of non-signatory observer states that have joined the TPNW meetings to learn more about the treaty has also grown. Their participation underscores that states inside and outside the TPNW can advance progress toward their shared goals: preventing nuclear war and moving closer to the peace and security of a world without nuclear weapons.
