A treaty on the prohibition of nuclear weapons was adopted by an overwhelming vote and met with loud cheers this week at the United Nations. More than 70 years in the making, the treaty offers widely agreed principles, commitments, and mechanisms for ending the nuclear weapons age. Getting here was not easy, and achieving nuclear disarmament will still be a long struggle. But the new treaty creates space and means for a creative new disarmament politics based on law and ethics and democracy that go beyond well-trodden debates on the dangers and costs of nuclear weapons and traditional practices of arms control based on step-by-step reductions that limit only the size of arsenals.
