Episode notes
Power Shifts Amplify War Risk
- A meteoric rising power beside a colossal ruling power creates psychological discombobulation that magnifies misperception and risk.
- Graham Allison finds that historically about three-quarters of such rivalries led to war, often via amplified accidents or third-party incidents.
Accidents Can Trigger Major Wars
- Small third-party incidents can trigger cascading reactions when great-power rivalry is high and trust is low.
- Misperceptions and miscalculations turn manageable events into uncontrollable escalation, Allison warns.
Cuban Missile Crisis Near Miss
- Allison recounts the Cuban Missile Crisis as a near-catastrophic close call that could've led to nuclear war.
- He credits statecraft, luck, and later systemic Soviet weaknesses for avoiding catastrophe.
