Webinar: “Golden Dome”: A Costly, Destabilizing, and Ineffective Missile Defense System

In May 2025, President Donald Trump approved the Defense Department’s architecture and implementation plan for “Golden Dome”—a multilayered missile defense system incorporating ground-, sea-, and space-based components designed to protect all U.S. territory from any scale of missile attack by any country. In this webinar, three physicists specializing in missile defense will examine why the proposed system would be technically ineffective, carry projected costs in the hundreds of billions of dollars or more, and exacerbate global arms race dynamics. They will also discuss how “Golden Dome” could heighten crisis instability and ultimately increase the risk of nuclear war.
