Jan 6, 2026
Aaron Bateman, Assistant Professor at George Washington University, delves into the Strategic Defense Initiative (SDI), sparked by Reagan’s 1983 announcement. He discusses how SDI reshaped space militarization post-Cold War, revealing its secretive role in US defense strategy. Bateman argues that SDI’s controversy stemmed more from its political implications than technical challenges. He also connects SDI's legacy to today's space arms control issues and reflects on current projects, including insights gained from archival research.

Episode notes
SDI Unified Missile Defense R&D
- The Strategic Defense Initiative (SDI) centralized diverse DoD R&D into a layered missile defense program under Reagan.
- SDI's controversy combined technical doubts with fears about its impact on strategic stability.
Missile Defense And ASATs Are Entangled
- Missile defense and anti-satellite (ASAT) technologies were fundamentally the same and thus politically entangled.
- This entanglement made arms-control limits on ASATs effectively constrain SDI development.
Reagan's Question And His Advisors' Reply
- Reagan asked if the U.S. could limit offensive space weapons while allowing defensive ones and even offered to give up ASATs.
- Advisors replied the technologies were indistinguishable and that constraints would block future space-based missile defense.
