John Tierney of Council for a Livable World on Peace and Security

With so much focus on our domestic problems, it’s easy to lose sight of the very serious challenges, conflicts, and threats that face us around the world: an Iran that could be within weeks of having the materials to make a nuclear bomb, an aggressive and nuclear-armed Russia, ongoing and tragic warfare in Yemen, and deep tensions in the strait of Taiwan involving nuclear-armed China which also wields the largest military in the world. Our guest John Tierney is the Executive Director at Council for a Livable World, a leading NGO focused on peace and security. He lays out smart approaches for how America can better navigate a hostile, dangerous world to reduce nuclear weapons, promote dialogue, and achieve greater peace and security.
