Washington DC Chain Reaction 2025 | Mobilize. Act. Disarm.

Join Ploughshares in Washington DC on Wednesday, October 22 from 12-2pm at Patterson Mansion for Chain Reaction 2025: Mobilize. Act. Disarm.

This year marks the 80th commemoration of the Trinity Test and the US bombings of Hiroshima and Nagasaki. It is an opportunity to reflect upon an important question: Can we learn from the mistakes of our nuclear history and pave the way for a safer future?

The rapidly changing nuclear landscape requires fast thinking and swift action. Ploughshares is uniquely positioned to support and guide the nuclear field through these crises using the lessons learned from our decades of experience to uncover innovative and longer-lasting solutions to one of the world’s greatest problems.

This year’s theme, “Mobilize. Act. Disarm.” is a call to action. Together, we must galvanize our community to fight for a safe and secure future for everyone, free from the threat of nuclear weapons. Now is a time for urgency.

A series of events so related that each one initiates the next is known as a chain reaction. Every year we gather leaders in our field, devoted partners, and new advocates to generate bold ideas and strategies to advance policies to reduce the threat of nuclear weapons. You — and every new ally you introduce to Ploughshares — represent critical innovators of change.

Know what’s Happening Next — before everyone else does.
