Elizabeth Warner Reflects on 13 Years at Ploughshares and the Path Ahead

After 13 transformative years at Ploughshares, Elizabeth Warner, the organization’s Executive Director, is stepping down. Warner’s tenure has been marked by pivotal achievements in the global nuclear disarmament landscape and a steadfast commitment to fostering equity and innovation within the organization.

In a reflective interview, Warner shared insights into her decision, the milestones she’s most proud of, and her outlook for the field of nuclear disarmament.

Passing the Baton

Warner’s decision to leave her role comes from a place of deep conviction about leadership and renewal.

“I fundamentally believe that a good leader makes space for new leadership to come in,” she said. “I’ve been here for 13 years, and it’s time to pass the baton. This issue deserves fresh perspectives, new energies, and ideas to carry it forward.”

This belief in the power of transition reflects Warner’s broader philosophy: ensuring the longevity and vitality of Ploughshares’ mission through dynamic leadership.

Reflecting on Milestones

When asked about the moments that stand out in her career, Warner pointed to several highlights:

• The JCPOA Agreement: Warner was involved in the early coalition-building efforts that culminated in the Joint Comprehensive Plan of Action (JCPOA), which prevented Iran from developing nuclear weapons. “Even with the agreement no longer in place, the fact that Iran has not developed nuclear weapons underscores the importance of that work.”
• Raising Awareness: Warner noted two Nobel Peace Prizes awarded during her tenure to organizations and leaders working in nuclear disarmament, elevating global awareness about the enduring threats of nuclear weapons.
• Groundbreaking Research: In 2014, Ploughshares supported research that unveiled the staggering $1 trillion cost of nuclear weapons systems, which has since ballooned to nearly $2 trillion. This work reshaped how policymakers and the public understand the financial implications of nuclear armament.
• Advancing Equity: Warner championed initiatives like the Women’s Initiative (which evolved into Equity Rises), embedding equity practices across the organization’s grants, hiring processes, and internal operations.

“Managing the transition from Joe Cirincione to Emma Belcher as president was another highlight,” Warner said. “It was a massive change for the organization, but seeing Emma’s vision come to life and ensuring the transition was seamless for our donors, staff, and grantees is something I’m deeply proud of.”

Challenges and Opportunities Ahead

Looking ahead, Warner identified key challenges for the nuclear disarmament field, including the need to attract new audiences and resources, prepare the next generation of leaders, and embrace innovation.

“How do we disrupt the status quo to make space for new leaders, ideas, and voices? That’s a challenge, but also an opportunity,” she said.

Despite funding challenges and the complexities of the nuclear disarmament landscape, Warner remains optimistic.

“Every conversation I have shows that people care deeply about this mission. The agreement that nuclear weapons pose a threat is universal once you break through the noise,” she said. “That gives me hope.”

What’s Next?

As for her own future, Warner is in a period of exploration.

“I don’t know what’s next yet, but I’m excited about the possibilities,” she shared. “I’m reflecting on what inspires me and how I can leverage the skills I’ve developed at Ploughshares to continue making the world a better place.”

A Legacy of Leadership

Warner leaves behind a legacy of transformative leadership, equity, and innovation. As Ploughshares enters a new chapter, her contributions will continue to shape its work and the broader movement for nuclear disarmament.

“This issue isn’t going away,” Warner said. “It deserves—and will have—leaders ready to take it forward with fresh ideas and unrelenting dedication. I’m honored to have played a role in this vital mission.”
