In view of the fact that in any future world war nuclear weapons will be certainly employed, and that such weapons threaten the existence of mankind, we urge the Governments of the World to realize, and to acknowledge publicly, their purpose cannot be furthered by a world war, and we urge them, consequently, to find peaceful means for the settlement of matters of dispute between them.
