Two nonprofit organizations, Physicians for Social Responsibility and N Square, sponsored the Nukebusters Short Film Contest last fall, and the Bulletinis delighted to feature the winner of the contest’s student category as part of our continuing efforts to reach young people with important information about existential threats to humanity. Watch Jonathan Deaton’s Joining the Conversation, and you’ll see what happens when young adults find out how many nuclear weapons there are in the world, and what those weapons actually cost.
