On March 23, 1983, in a televised address to the nation, President Reagan announced his intention to embark upon groundbreaking research into a national defense system that could make nuclear weapons obsolete. At the heart of the Strategic Defense Initiative was the development of a space-based missile defense program that could protect America from a large-scale nuclear attack. Flash forward to today, and now our country has the Missile Defense Agency to develop and deploy a system to defend the United States and its allies - exactly what President Reagan envisioned 40 years ago. On August 1, 2024, the Reagan Foundation was honored to host an in-person event with Lt. Gen. Heath Collins, the Director of the Missile Defense Agency, whose job it is to advise the Under Secretary of Defense for Research and Engineering on Missile Defense programmatic policy, requirements, priorities, systems, resources, and programs. During the program, Lt. Gen. Collins sat down in conversation with Reagan Foundation and Institute President and CEO David Trulio to discuss the Missile Defense Agency - its responsibilities, its challenges and opportunities, and the importance of what the Agency does every day for our nation's security.
