Moreover, international nuclear arms control and disarmament agreements among the nuclear powers have collapsed. Some called for dramatically strengthened global governance to prevent the outbreak of nuclear war, while others, with the same goal in mind, championed nuclear disarmament. Then, at the 2017 conference, the national delegates voted 122 to 1 to adopt the UN Treaty on the Prohibition of Nuclear Weapons (TPNW), which banned nuclear weapons. Today, most rulers of the nuclear powers are nationalistic, militaristic, and authoritarian, with no interest in nuclear disarmament. Thus, unless there is an advent of new, less hawkish rulers, a movement revival, or both, a nuclear war seems likely.
