Four years into Russia's full-scale invasion of Ukraine, North Korea has sent an estimated 15,000 to 20,000 troops to Russia's Kursk region since October 2024, suffering roughly 6,000 casualties, according to intelligence from South Korea and the United Kingdom. The deployment, which has no direct connection to Pyongyang's national interests in Ukraine, has prompted questions about what Kim Jong Un hopes to gain from the sacrifice.
For a military that has not fought a large-scale war since the Korean War armistice in 1953, the experience gained on the Ukrainian front is tremendously valuable, according to analysts. The bloodshed has yielded practical battlefield lessons, from drone warfare coordination to logistics under fire, that North Korea could not acquire through exercises or training alone.
Ukrainian officials have indicated that North Korea may be asked to contribute tens of thousands more troops, suggesting the relationship between Pyongyang and Moscow is deepening. The diplomatic and material returns for North Korea, while not yet fully public, are believed to include advanced military technology transfers, economic aid, diplomatic backing at the United Nations and reduced international isolation.
Neither North Korea nor Russia has publicly declared a formal military alliance, and the deployment has been conducted without a public declaration of belligerency by Pyongyang. The arrangement reflects a pragmatic transaction: Russia gets much-needed manpower for its grinding war effort, and North Korea gets modern combat experience and resources that strengthen Kim Jong Un's regime at home and abroad.
Analysis
Why This Matters
- North Korea's direct military involvement in a European war breaks decades of non-intervention and signals a new level of cooperation with Russia, reshaping security dynamics in Northeast Asia.
- Thousands of North Korean casualties may weaken the Korean People's Army's readiness on the Korean Peninsula, but the combat experience gained could ultimately make Pyongyang's forces more capable in any future conflict.
- The deployment sets a precedent for other authoritarian states to offer troops in exchange for military and economic support, potentially expanding the scope of proxy warfare.
Background
North Korea has one of the world's largest standing armies but almost no modern combat experience. Its troops have not fought a large-scale war since 1953, and training has been largely limited to exercises and border skirmishes. Since 2022, North Korea has steadily deepened ties with Russia, providing artillery shells and now troops for the Ukraine war. In return, Russia has provided food aid, fuel and likely missile and nuclear technology assistance, though details remain opaque. The arrangement fits Kim Jong Un's longstanding goal of modernizing his military while breaking out of diplomatic isolation.
Key Perspectives
Pyongyang: The Kim regime views the deployment as a low-risk way to gain real-world combat experience, test equipment and tactics, and secure Russian support for its own military programs, including its ballistic missile and nuclear ambitions. The casualties, while heavy, are seen as an acceptable cost for these strategic gains.
Ukraine and allies: Kyiv and its partners see North Korea's involvement as an escalation that prolongs the war and undermines efforts to isolate Russia. They have called for stronger sanctions and international condemnation, but enforcement remains difficult.
South Korea and the broader region: Seoul fears that a battle-hardened North Korean military, combined with Russian technology transfers, could destabilize the peninsula. The deployment also threatens to shift the balance of power in East Asia, prompting closer defense cooperation between South Korea, Japan and the United States.
What to Watch
- Whether North Korea agrees to send the additional tens of thousands of troops that Ukrainian officials have suggested Russia is requesting.
- The scale and nature of Russian technology transfers to North Korea, particularly in missile, nuclear and drone fields, which could be revealed through defectors or satellite imagery.
- The reaction from China, North Korea's main ally, which has so far taken a cautious position on the troop deployment.
- Casualty trends: declining morale or mutiny within North Korean units could limit the duration of the mission.
