Article VI requires all of its state parties 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." The article does not specify a time frame or verification mechanism for disarmament, but it places a legal obligation on states with nuclear weapons to stop the nuclear arms race and to eventually disarm. As such, this obligation is one of the three main "pillars" of the treaty, the other two being nuclear nonproliferation and the right to use nuclear technology for peaceful purposes.
