Flash and fire consumed Hiroshima’s streets when the United States dropped an atomic bomb 80 years ago. Days later, Nagasaki would also be engulfed in flames. Upwards of 120,000 people were instantly killed, and many more would suffer and die in the fallout.

Decades later, the world has failed to learn the lessons. Today, nine countries — several of which are already at, or terrifyingly close to, war — possess the destructive power of 135,000 Hiroshima bombs.

And just recently, Trump ratcheted up tensions further, ordering two U.S. nuclear submarines near Russia.

It’s a chilling reminder that, at any minute, the U.S. President can single-handedly launch a weapon capable of horrific destruction. No approval from, not even notification to, the Defense Secretary or Congress is required.

The system is designed for speed, not clear-headed, democratic decision making. That’s why we need policies like “No First Use” in place immediately.

The Restricting First Use of Nuclear Weapons Act (S.192 and H.R.669), would create the guardrails necessary to stop Trump — or any president — from unilaterally pushing us down the path to nuclear catastrophe, and it needs your urgent support.
