"Each of the Parties to the Treaty undertakes to pursue negotiations in good faith on effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament, and on a treaty on general and complete disarmament under strict and effective international control."
Note that this part of the Treaty does NOT say that they have to continually pursue negotiations until the end of time. All they had to do was pursue negotiations ONCE in order to fulfill the Treaty.
There were regular nuclear disarmament negotiations during the 1970s and 1980s - right up until the point where one of the participants in the NNPT effectively disbanded.
