From the prophets' dreams of the time when nations would beat their swords into plowshares to today's aspirations of a nuclear-weapons-free world, we have sought to avoid armed conflict and not yield to despair in the search for universal peace. The nuclear threats from Iran, North Korea, and terrorists can only be overcome through international cooperation. We call upon Congressional leaders and those worldwide to join together to ensure the fulfillment of these long-overdue initiatives and the achievement of a safer future without nuclear weapons.
