Nuclear Ban Treaty Nears 50th Ratification


September 2020

Four nations used the occasion of the 75th anniversary of the U.S. atomic bombings of Hiroshima and Nagasaki to announce their ratification of the 2017 Treaty for the Prohibition of Nuclear Weapons (TPNW). The ratifications by Ireland, Nigeria, and Niue, announced on Aug. 6, and Saint Kitts and Nevis, announced on Aug. 9, bring the number of states ratifying the accord to 44. The treaty will enter into force 90 days after the 50th state deposits its instrument of ratification. To date, 82 states have signed the treaty.

The TPNW is the first international instrument to comprehensively ban the development, testing, production, stockpiling, stationing, transfer, use, and threat of use of nuclear weapons. All states-parties engaging in these activities are bound to submit and implement a plan to divest themselves completely of nuclear weapons upon ratification.

At an Aug. 6 event to mark the new ratifications, Elayne Whyte Gomez of Costa Rica, who presided over the negotiations on the treaty, called for renewed determination to ensure that no other city suffers the same as Hiroshima and Nagasaki. She noted that “the presence in the room of the hibakusha ensured that we wouldn’t leave the room without completing the task.”

Tijjani Muhammad-Bande of Nigeria, the current president of the UN General Assembly, called on “all member states to sign and ratify [the TPNW]. We must prevent such destruction from ever happening again.”

Treaty supporters hope to secure the additional ratifications necessary to bring the treaty into force by the end of 2020. More states are expected to ratify the treaty next month as the United Nations on Sept. 26 marks the International Day for the Total Elimination of Nuclear Weapons.—DARYL G. KIMBALL
