Cultural Leaders for a Future Without Nuclear Weapons

Pledge to build a critical mass against nuclear catastrophe.

Culture change precedes policy change. We partner with cultural leaders to engage the public and build a critical mass against nuclear risks through memorable art and powerful storytelling in film, on TV, and online. Join us.

Critical Mass Pledge

We believe nuclear weapons pose an unacceptable risk to our civilization and our security. We stand firmly against a costly new arms race and the development of more nuclear weapons. And we call on leaders to take action to ensure that a nuclear weapon is never used again.

This is a public commitment to use our voices, platforms, leadership, and storytelling expertise to call attention to the dangers posed by nuclear weapons and help audiences imagine a safer future without them.

Together, we can build a critical mass to demand our leaders move us closer to—and eventually reach—a world without nuclear weapons.

The Critical Mass Pledge is endorsed by Governor of Hiroshima Hidehiko Yuzaki, Governor of Nagasaki Kengo Oishi, and Co-Chair and CEO of NTI Ernest J. Moniz.

The pledge was originally published as part of a public statement from cultural leaders commemorating 80 years since the U.S. atomic bombings. The statement ran in The New York Times and Variety on August 6, 2025, and was covered in Billboard, The Wrap, and Politico.
