Our scientists assure us that this is a realistic step, that the cessation of manufacture could be controlled. Unlike the mere suspension of tests, this would be a real measure of disarmament. It would call a halt to the nuclear armaments race. If the Powers which now possess these weapons would agree that they would produce no more fissionable material for weapons purposes after a certain date in the future, other countries might be dissuaded from pursuing their own nuclear programmes for military purposes. In this way alone, I believe, can we prevent a competition in the manufacture of nuclear weapons in which many countries might join.
