The award-winning Oppenheimer film has brought attention to the origins of the atomic bomb and the anguish of its inventor. Almost 80 years after that first explosion in New Mexico, the threat of global Armageddon not only remains but has increased. Until and unless nuclear weapons are abolished, humankind will always be in danger of massive death and destruction. Yet instead of moving toward abolition, the U. S. is upgrading its arsenal. The Doomsday Clock is ticking. Sooner or later, intentionally or unintentionally, terminal war will destroy the planet. The only way to prevent that from happening is to eliminate all nuclear weapons. As long as they exist, humanity hangs by a thread.
