The prohibition on possession and stockpiling

At the beginning of 2023, the nine nuclear-armed states had a combined inventory of approximately 12,512 nuclear warheads, which is evidently not compatible with the TPNW’s prohibition on possession and stockpiling of nuclear weapons. An estimated 9,576 of the total inventory are stockpiled warheads that are available for use by the military. The remaining 2,936 warheads had previously been retired and are awaiting dismantlement in Russia and the United States.
