Graham Allison on the Risks of a US-China War

November 27, 2025

Key Takeaways Copied to clipboard!

  • The central theme of the discussion, introduced by Professor Graham Allison, is the Thucydides Trap, where the rise of a new power (China) instills fear in the established ruling power (US), historically leading to war in about three-quarters of observed cases. 
  • Economic entanglement, while often cited as a preventative measure against conflict (as seen in early 20th-century theories), is not a guarantee against geopolitical rivalry, though it may necessitate a complex strategic concept involving both fierce competition and necessary cooperation. 
  • Current US-China tensions are driven by structural shifts in power (China's rise) and perceptions of US decline, but potential circuit breakers include the shared recognition of catastrophic nuclear war risk and the mutual economic dependency that forces a degree of cooperation.

  • Key Takeaway: The episode introduces Graham Allison, who popularized the Thucydides Trap framework to describe the heightened risk of war when a rising power threatens an established one, specifically focusing on the US-China dynamic.
  • Summary: The hosts welcome Professor Graham Allison, the expert who coined the term Thucydides Trap. This framework analyzes the potential for violent conflict when a rapidly rising power challenges a ruling power. The conversation aims to explore the conditions driving this risk between the US and China.
Defining the Thucydides Rivalry

(00:05:37)
  • Key Takeaway: The US-China dynamic fits the Thucydides Trap because China is a meteoric rising power challenging the US, a colossal ruling power, leading to a ‘discombobulation’ that historically results in war three-quarters of the time.
  • Summary: Allison defines the rivalry by comparing China’s rapid rise to the US’s long-standing dominance, likening the shift in power to a seesaw tilting. This structural shift causes misperceptions and miscalculations, often escalating minor third-party incidents into major conflicts, as seen in the lead-up to World War I.
Historical Precedents and Cold War Analog

(00:13:37)
  • Key Takeaway: Out of 16 historical cases matching the rising/ruling power dynamic over 500 years, 12 resulted in war, but the US-Soviet Cold War serves as a non-war analog where internal contradictions eventually hollowed out the Soviet system.
  • Summary: The Cold War is presented as one of four cases that avoided outright war, partly due to brilliant statecraft and good fortune, but also because the Soviet command system proved economically uncompetitive over the long run. China’s leaders may perceive the US as similarly decadent and internally divided.
China’s Unique Foreign Policy Posture

  • Key Takeaway: Unlike the Soviet Union, China historically lacks a missionary impulse to convert other nations to its system, instead seeking respect and dominance within its own sphere, as observed by Lee Kuan Yew.
  • Summary: China’s historical view centers on being the ‘Middle Kingdom,’ demanding respect rather than ideological conversion, contrasting sharply with the Soviet Union’s communist expansionism. This difference means China’s global interest may remain more focused on trade and territorial periphery rather than global governance imposition.
Globalization Theory and Entanglement

(00:21:49)
  • Key Takeaway: The early 20th-century belief that economic entanglement prevents war, similar to early 2000s globalization optimism, proved to be a ‘grand illusion’ leading up to World War I, though current US-China entanglement might offer a complex stabilizer.
  • Summary: The idea that deep economic ties preclude war is historically flawed, as demonstrated by the lead-up to WWI. However, the current US-China entanglement is so profound that it might force a necessary cooperation for mutual survival, balancing the Thucydidean rivalry.
US Internal Contradictions and Chinese Perception

(00:31:37)
  • Key Takeaway: Chinese policymakers, particularly those close to Xi Jinping like Wang Huning, view the US as strangely contradictory and structurally declining, citing examples like New York electing a socialist mayor while facing massive income inequality.
  • Summary: Chinese observers are reportedly confused by US internal divisions, seeing phenomena like wealth concentration and social unrest as signs of inevitable splintering. This perception reinforces the Chinese belief in their own inexorable rise and the US’s irreversible decline.
Identifying War Warning Signs

  • Key Takeaway: Most daily headlines regarding US-China military buildup are ‘China hype,’ but the true danger lies in third-party initiatives, particularly actions by Taiwan’s leadership, that could trigger accidental escalation via ship or plane collision.
  • Summary: The most likely trigger for conflict is an accident in the Taiwan Strait or South China Sea, given current close-quarters military maneuvers. Effective communication channels between the US and China are crucial to act as a circuit breaker should such an accident occur.
Supply Chain Dependency and Resilience

(00:44:23)
  • Key Takeaway: Politicians declaring independence from Chinese supply chains (e.g., rare earth magnets, pharmaceuticals) is predictable, but the reality is that deep entanglement may lead to a managed state of mutual deterrence, similar to the nuclear balance.
  • Summary: Dependency on China for critical materials like rare earth magnets, essential for both civilian and military technology, creates vulnerability. While independence is declared, the practical reality suggests continued entanglement, potentially leading to a stable, albeit complex, mutual deterrence.
