Korean Military Balance Summary

Core Content

This report provides a comprehensive analysis of the military balance between North and South Korea, as well as key neighboring states such as China, Japan, and the United States. It highlights the complexity and uncertainty of the region's security dynamics, particularly in the context of conventional, nuclear, and asymmetric warfare. The analysis is based on data from Western, South Korean, and Japanese sources, with limited information from North Korea and China.

Main Points

1. Uncertainty in Military Balance

• There is no single Korean military balance that can be used for policy planning or arms control due to the high level of uncertainty and potential for escalation.
• Conflicts could arise from unpredictable incidents or patterns of escalation, and the likelihood of less probable forms of war has historically been higher than expected.
• The involvement of China and the United States adds layers of complexity, making the security environment highly volatile.

2. Military Expenditures and Resources

• North Korea: Military spending is significantly underestimated in official reports. The state-run Korea Institute of Defense Analyses (KIDA) estimates that North Korea's defense budget reached nearly USD9 billion in 2009, which is 15 times higher than the official USD570 million figure.
• South Korea: Military spending is more transparent, but still represents a significant portion of GDP (around 22% in 2009 based on PPP).
• China and Japan: Military spending data for China are highly controversial and lack standardization. Japan's spending is relatively low compared to South Korea and the U.S., but its military modernization is progressing.
• U.S.: The U.S. plays a central role in the region's military balance through its alliances with South Korea and Japan, and its extensive military presence in the Pacific.

Conventional Military Balance

• The balance of conventional forces is influenced by the role of U.S. forces, Japan's support for U.S. basing, and China's potential intervention to protect North Korea.
• North Korea has a large and modernized force structure, including extensive artillery and tunnel systems near the DMZ, which are used to exert pressure on South Korea and the U.S.
• South Korea has been developing its military capabilities more rapidly, with a focus on modern aircraft and surface-to-air missiles, and has a comprehensive modernization plan through 2020.
• The risk of conventional conflict is high, but the perception of capability and risk differs significantly between the two Koreas, increasing the potential for miscalculation.

Asymmetric and Irregular Warfare

• North Korea has a long history of using asymmetric and covert operations to challenge South Korea and the U.S., including sabotage, terrorism, and kidnappings.
• Notable incidents include the Cheonan ship sinking (2010) and the Yeonpyeong artillery attack (2010), which demonstrate North Korea's willingness to escalate tensions.
• These actions are often used to divert attention from internal issues and create a sense of external threat.

Nuclear and CBRN Warfare Balance

• North Korea: Has conducted two low-yield nuclear tests and is suspected of having a covert nuclear weapons program. It may have 4–13 nuclear weapons based on plutonium from reactors, and is developing both nuclear and chemical/biological weapons.
• Nuclear Capabilities: North Korea is believed to have implosion-based fission weapons and is likely developing boosted and thermonuclear weapons.
• Missile Programs: North Korea has developed various missile systems, including Scud, No Dong, Taepodong, and Musudan, with varying degrees of operational capability and accuracy.
• CBRN Threats: North Korea is suspected of having chemical, biological, and radiological weapons, which could be delivered via missiles or other means. These capabilities pose a significant threat, especially given the potential for asymmetric and covert attacks.
• U.S. and China: Both have advanced nuclear and missile capabilities, including ICBMs, IRBMs, and MRBMs. The U.S. also has precision-guided weapons and cyber warfare capabilities that could be used in both defensive and offensive roles.

Weapons of Mass Effectiveness and Strategic Implications

• The balance of offensive and defensive weapons is critical in shaping the strategic environment. Defensive systems such as missile defense and cyber warfare can be as potent as offensive weapons.
• The "Nth weapon paradox" suggests that reducing nuclear stockpiles may increase the risk of targeting civilian infrastructure due to the reduced deterrent effect.
• The "diversion effect" implies that nuclear controls may push states toward more dangerous chemical and biological weapons, which are harder to regulate and more lethal.

Key Neighboring States and U.S. Presence

• U.S. Forces in Korea: The U.S. maintains a significant military presence in South Korea, including troops, bases, and advanced weapons systems, which plays a crucial role in deterring North Korean aggression.
• U.S. Forces in Japan: The U.S. also has a strong military presence in Japan, which could be drawn into a conflict with North Korea, potentially escalating tensions with China.
• China's Role: China is a major regional power with conventional and long-range missile capabilities, and may intervene in a conflict to protect North Korea. It is also developing advanced missile defense systems and has anti-satellite and EMP capabilities.

Conclusion

The Korean military balance is shaped by a complex interplay of conventional, nuclear, and asymmetric forces, with significant uncertainties due to the lack of transparency and reliable data from North Korea and China. The potential for escalation, especially in the context of nuclear and CBRN threats, remains a major concern for regional stability. The U.S. and its allies are central to maintaining the balance, but their actions could also provoke China and lead to broader strategic consequences.
