Episode notes
Strategic Deterrence Targets Leaders
- Strategic deterrence targets decision-makers with tools like nuclear weapons and non-nuclear systems that have strategic effects.
- Fiona Cunningham explains strategic deterrence focuses on what tools threaten leadership-level choices rather than battlefield commanders.
Space Shifted From Support To Target
- Space transformed from an enabling domain into an arena of dependency and vulnerability during and after the Cold War.
- Aaron Bateman notes the US became highly dependent on space systems while adversaries developed counter-space tools.
Deterrence Varies With Political Goals
- Nuclear deterrence logic is similar across powers, but what states threaten to deter differs by objectives and capabilities.
- Fiona Cunningham stresses China tailors nuclear roles to limited local wars rather than existential defense alone.
