CHINA IN THE WORLD PODCAST: U.S. Nuclear Doctrine and Nonproliferation in East Asia

Summary

Core Content

This episode of the Carnegie-Tsinghua China in the World podcast, hosted by Tong Zhao and featuring Elbridge Colby, discusses the evolving U.S. nuclear doctrine in the context of rising military powers in East Asia, particularly China and Russia. Colby, a former U.S. defense policy advisor and fellow at the Center for a New American Security, emphasizes the need for the United States to maintain a strong and flexible nuclear deterrent in light of increasing conventional military capabilities from China and Russia.

Main Views

• U.S. Nuclear Policy under Carter: Colby suggests that Secretary of Defense Ash Carter will continue the Obama administration's rhetorical focus on reducing nuclear weapons but will also support the modernization and recapitalization of the U.S. nuclear arsenal. This includes maintaining a strong nuclear deterrent, which he views as essential for U.S. strategic posture.
• Flexible Nuclear Posture: Colby advocates for a more flexible and tailored nuclear posture, one that is adaptable to current and emerging strategic realities. This flexibility is not about making nuclear weapons more usable, but rather ensuring their strategic relevance and effectiveness in a new geopolitical landscape.
• Conventional Gap and Nuclear Compensation: While the U.S. has traditionally relied on its conventional military superiority, Colby argues that the growing conventional capabilities of China and Russia may necessitate a greater role for nuclear weapons in U.S. strategy. He warns that if the U.S. fails to maintain its nuclear deterrent, it could lead to a loss of credibility in its extended deterrence commitments to allies in the region.
• U.S. Alliances in East Asia: Colby highlights the importance of the U.S. alliance network in East Asia, including Japan, South Korea, and others. He believes that these allies are better off relying on the U.S. nuclear umbrella rather than developing their own nuclear capabilities. However, he acknowledges that if the U.S. fails to provide credible deterrence, these allies may consider nuclear options themselves.
• U.S.-Russia Nuclear Relations: Colby notes that the new START treaty, which he helped draft, is a critical framework for arms control. He argues that arms control should focus on stability and reducing risks of escalation, rather than on disarmament. He believes that the U.S. and Russia need to avoid misinterpretations of each other's military actions, especially in the context of missile defense and regional tensions.

Key Information

• Strategic Context: The U.S. must adapt its nuclear policy to the realities of China's military buildup and Russia's resurgence.
• Modernization Programs: The U.S. is modernizing its nuclear triad (strategic bombers, ICBMs, and nuclear submarines), but Colby emphasizes that software changes—such as nuclear doctrines and command and control systems—are equally important.
• Nonproliferation Concerns: Colby warns against the proliferation of nuclear weapons by U.S. allies, arguing that it could undermine regional stability and U.S. influence.
• Arms Control as a Tool for Stability: Colby advocates for arms control measures that enhance understanding and reduce the risk of accidental or unintended escalation, rather than focusing solely on reducing nuclear stockpiles.

Conclusion

Colby concludes that the U.S. must balance its rhetorical commitment to nuclear disarmament with the practical need for a robust and flexible nuclear deterrent. He believes that arms control should be a tool for stability rather than an end goal of disarmament. The U.S. should continue to work with both Russia and China to reduce nuclear risks, even if this means moving away from an ideal of a world without nuclear weapons.

Additional Notes

• The U.S. and China should engage in constructive dialogue to reduce the risk of escalation in the region.
• Colby draws a parallel between China's rise and Germany's historical trajectory, suggesting that China's growing power may lead to regional instability if not managed carefully.
• The U.S. should not retreat from its global leadership role and must maintain its strategic posture in the face of rising competitors.
