Putin and Kim’s Expanding Military Alliance: What the Reported 50,000 North Korean Troop Deployment Could Mean
By Unknown Chapter | August 12, 2026
Introduction
The military relationship between Russia and North Korea has entered a new and increasingly consequential phase.
What began as a closer strategic partnership between Moscow and Pyongyang has developed into direct military cooperation connected to the war in Ukraine. Now, a new claim from Ukrainian President Volodymyr Zelenskyy has intensified international attention: Russia could receive up to 50,000 North Korean troops.
Zelenskyy said on August 9 that the potential deployment would represent a significant increase from earlier estimates of North Korean involvement. Reuters reported that Zelenskyy cited intelligence sources but did not publicly identify them. Earlier estimates had placed the number of North Korean troops involved at around 30,000.
The figure of 50,000 is therefore important—but it should be treated as a reported estimate, not a confirmed number of troops already deployed.
The development is significant because North Korea has already provided personnel and military equipment to Russia. In 2024 and 2025, thousands of North Korean soldiers were reported to have operated in Russia’s Kursk region, while Western and South Korean assessments documented substantial casualties among those forces.
At the same time, Russia and North Korea have formalized their relationship through a comprehensive strategic partnership treaty that includes a mutual military-assistance provision. The treaty entered into force in December 2024.
This raises a much larger question:
Is the Russia–North Korea relationship becoming a long-term military alliance capable of changing the balance of power in Europe and Asia?
The 50,000-Troop Claim
The latest development centers on Zelenskyy’s warning that North Korea may send or station as many as 50,000 troops in Russia.
Reuters reported that Zelenskyy’s latest figure was significantly higher than his previous estimate of around 30,000. He also said North Korea was using the Ukraine war as an opportunity to gain experience in modern warfare and military technology.
This distinction matters.
The headline “50,000 North Korean soldiers are already in Ukraine” would be misleading. Available reporting describes the figure as a potential or planned deployment to Russia, rather than proof that 50,000 North Korean troops are currently fighting on the Ukrainian battlefield.
That difference is critical when evaluating the story.
Nevertheless, even a deployment substantially smaller than 50,000 would represent a major development.
North Korea possesses one of the world's largest standing militaries, and its forces have extensive experience with large-scale mobilization, artillery operations, and highly centralized military command structures. What they have historically lacked is extensive experience against a technologically sophisticated opponent in a modern battlefield environment dominated by drones, electronic warfare, precision weapons and real-time surveillance.
The war in Ukraine provides exactly that environment.
From Strategic Partnership to Battlefield Cooperation
The relationship between Vladimir Putin and Kim Jong Un changed dramatically in 2024.
In June 2024, Putin traveled to Pyongyang, where Russia and North Korea signed a Comprehensive Strategic Partnership Treaty.
The agreement included a mutual military-assistance provision, meaning that the relationship was no longer simply diplomatic or economic.
According to reporting on the treaty, both countries committed to assisting each other in the event of armed aggression. The agreement entered into force on December 4, 2024, after the two sides exchanged ratification instruments.
This created a formal framework for deeper cooperation.
Soon afterward, reports emerged that North Korea had deployed thousands of troops to Russia.
By late 2024, South Korean and Western officials were estimating that approximately 10,000–11,000 North Korean troops had been sent to Russia. Ukrainian intelligence and other governments said many were being prepared for operations in the Kursk region.
The relationship had moved from political cooperation to military cooperation.
Why Kursk Became Important
The Kursk region became one of the first major testing grounds for North Korean troops.
In August 2024, Ukrainian forces launched an unexpected cross-border offensive into Russia's Kursk region and seized territory.
Moscow responded by building a large force to retake the area.
By November 2024, U.S. and Ukrainian officials estimated that approximately 50,000 Russian and North Korean troops had been assembled for a counteroffensive in Kursk. At that time, the 50,000 figure referred to the combined Russian and North Korean force, not 50,000 North Korean soldiers.
That historical context is important because the phrase “50,000 troops” has appeared in reporting before—but it has not always referred to North Korean troops alone.
North Korean forces subsequently participated in fighting in the Kursk region.
Russia later acknowledged their involvement, while North Korea publicly confirmed that its troops had been sent to support Russia.
The Cost of the First Deployment
The first North Korean deployment appears to have come at a significant human cost.
In April 2025, South Korea's National Intelligence Service estimated that approximately 15,000 North Korean troops had been sent to Russia and that around 4,700 had become casualties, including roughly 600 deaths.
Two months later, Britain's Ministry of Defence assessed that North Korean casualties in the Kursk fighting had exceeded 6,000 killed or wounded, representing more than half of the approximately 11,000 troops initially deployed there. The British assessment attributed the high casualty rate largely to intensive dismounted assaults.
These figures demonstrate why the potential expansion of North Korean involvement is so significant.
North Korea is not simply sending troops into a training exercise.
Its personnel have already experienced one of the world's most technologically advanced and dangerous land wars.
What North Korean Soldiers Learned
The battlefield in Ukraine is very different from the wars of previous decades.
Modern combat is increasingly shaped by:
- Small first-person-view drones
- Long-range strike systems
- Electronic warfare
- Satellite surveillance
- Precision artillery
- Counter-drone systems
- Real-time battlefield intelligence
- Rapid targeting networks
North Korean soldiers initially suffered heavy losses, according to Ukrainian accounts.
But battlefield experience can also produce rapid adaptation.
NPR reported in 2025 that Ukrainian soldiers who fought North Korean troops described a shift from more traditional infantry tactics toward greater use of drones and electronic warfare.
That experience could have consequences far beyond Ukraine.
If North Korean personnel return home after gaining practical experience with modern battlefield technology, they could potentially transfer those lessons into North Korea's military training system.
This is one of the reasons South Korea and other regional powers are watching the Russia–North Korea relationship so closely.
Why Would North Korea Send More Troops?
There are several possible reasons.
1. Military Technology
North Korea has long pursued advanced missile and nuclear capabilities despite international sanctions.
Russia, meanwhile, possesses decades of experience in missile engineering, aerospace technology, electronic warfare, air defense, satellite systems and military operations.
Closer military cooperation could give Pyongyang access to knowledge and technologies that would otherwise be difficult to obtain.
Zelenskyy has specifically warned that North Korea could gain modern warfare experience and military technology through its cooperation with Russia.
2. Battlefield Experience
North Korea's military is large, but practical experience in modern high-intensity warfare is limited.
Ukraine has become a laboratory for modern warfare.
By participating, North Korean forces can observe how drones operate, how electronic warfare affects battlefield communications, how artillery is coordinated and how modern air-defense networks respond to missile and drone attacks.
3. Economic Benefits
North Korea faces severe economic restrictions and international sanctions.
Military cooperation with Russia can potentially create new economic opportunities for Pyongyang, including payments, energy supplies, food assistance and other forms of economic cooperation.
4. Strategic Partnership With Moscow
North Korea also has an obvious geopolitical interest in maintaining strong relations with Russia.
For Pyongyang, Moscow provides an important international partner at a time when North Korea remains heavily isolated from much of the global economy.
For Russia, North Korea provides manpower, ammunition and military support.
The relationship can therefore benefit both sides.
What Does Russia Gain?
For Moscow, the biggest advantage may simply be manpower.
The war in Ukraine has placed enormous demands on Russian forces.
If North Korean troops can perform infantry, security or other battlefield roles, Russia may be able to redirect some Russian personnel to other missions.
The potential deployment also gives Moscow access to another source of military manpower without relying entirely on domestic mobilization.
This is strategically important.
A large-scale war is not only a contest of weapons.
It is also a contest of industrial capacity, logistics, manpower and political endurance.
The ability to draw on foreign military personnel could therefore strengthen Russia's ability to sustain a prolonged conflict.
North Korean Missiles Are Also Part of the Story
The relationship between Moscow and Pyongyang is not limited to soldiers.
Ukraine has also reported the use of North Korean-made ballistic missiles by Russian forces.
On August 10, 2026, Reuters reported that Ukrainian officials said North Korean ballistic missiles were used in a Russian strike on the Zaporizhzhia region. Russia did not confirm the Ukrainian claim.
The report came shortly after Ukraine warned about a North Korean missile unit reportedly operating in western Russia.
According to Reuters' August 9 reporting, Ukrainian military intelligence said a North Korean missile unit could potentially involve 120 ballistic missiles and six launchers.
If verified, this would represent another stage in the Russia–North Korea military relationship.
The partnership would no longer be primarily about personnel.
It would involve weapons, logistics, training, battlefield experience and potentially military technology.
Could 50,000 Troops Change the War?
The answer depends on what those troops are actually used for.
A force of 50,000 additional personnel would be significant.
But numbers alone do not determine battlefield effectiveness.
Modern warfare requires:
- Training
- Logistics
- Intelligence
- Communications
- Air defense
- Artillery support
- Armored vehicles
- Medical evacuation
- Ammunition
- Drone capabilities
- Command and control
If North Korean forces are deployed as large infantry formations without adequate protection, they could suffer severe losses.
The experience of 2024–2025 already demonstrated the dangers of deploying troops into drone-dominated battlefields.
But if Russia integrates North Korean personnel into a broader Russian command and logistics system, the impact could be more substantial.
The most important question may therefore not be:
“How many North Korean soldiers are coming?”
Instead, it may be:
“How effectively can Russia integrate them into modern combined-arms warfare?”
The “Daredevil” Label
Online discussions sometimes describe North Korean soldiers using dramatic terms such as “Daredevils,” portraying them as fearless or almost unstoppable fighters.
That language makes for powerful headlines, but it should be treated cautiously.
There is no reliable evidence that 50,000 North Korean troops constitute a formally designated military formation called the “Daredevils.”
North Korean troops have been described by Ukrainian and Russian sources as disciplined and willing to continue operations despite heavy losses, but battlefield performance varies considerably depending on training, leadership, equipment, intelligence and mission.
Therefore, the idea of a mysterious army of 50,000 “Daredevils” should be understood as a media-style description rather than an established military designation.
A New Triangle: Russia, North Korea and China
The Russia–North Korea relationship also has consequences for China.
Beijing remains North Korea's most important historical economic partner, while Russia has increasingly become another major strategic partner for Pyongyang.
China has generally sought to avoid being directly pulled into the Russia–Ukraine war.
But if Russia and North Korea continue deepening their military relationship, the strategic environment in East Asia could become more complicated.
North Korea could gain:
- Battlefield experience
- New military technology
- Stronger diplomatic backing
- Greater access to Russian systems
- More confidence in its military posture
South Korea and Japan are therefore watching developments in Ukraine for lessons that could eventually apply to the Korean Peninsula and wider Indo-Pacific region.
Why South Korea Is Concerned
The consequences are particularly important for South Korea.
The Korean Peninsula is already one of the most heavily militarized regions on Earth.
North Korea possesses a large military, ballistic missiles and nuclear weapons.
South Korea has advanced conventional forces and a close security relationship with the United States.
If North Korean soldiers gain years of modern battlefield experience in Ukraine, they could potentially return with knowledge of technologies and tactics that were previously unavailable to them.
NPR reported in 2025 that experts viewed North Korean battlefield experience with drones and other modern systems as a potential future concern for South Korea.
That means the Ukraine war could have consequences thousands of kilometers away.
Is Putin Preparing for World War?
This is where headlines can easily become exaggerated.
The growing Russia–North Korea relationship is undeniably significant.
But there is no confirmed evidence that Putin and Kim are preparing to launch a global world war.
The phrase “World War preparation” is therefore best understood as a description of rising geopolitical concern rather than a verified military plan.
Russia is fighting a major war in Ukraine.
North Korea is expanding its military cooperation with Russia.
The two governments have a treaty that includes mutual assistance.
North Korean troops have already participated in combat connected to the Ukraine war.
North Korean weapons have reportedly been used by Russian forces.
All of these facts indicate a major strategic shift.
But they do not automatically mean that Russia and North Korea are planning a worldwide conflict.
The Bigger Picture: A War Becoming International
One of the most important lessons from the Russia–Ukraine conflict is that modern wars rarely remain isolated.
The Ukraine war has increasingly involved weapons, technology, intelligence, money and personnel from multiple countries.
Russia has deepened military cooperation with North Korea and Iran.
Ukraine receives extensive support from the United States and European countries.
China remains economically connected to Russia while carefully managing its own strategic interests.
The result is a conflict with increasingly global consequences.
The reported possibility of another large North Korean deployment is therefore important not simply because of the number of soldiers.
It demonstrates how the war continues to reshape international military relationships.
What Happens Next?
Several scenarios are possible.
Scenario One: Limited Deployment
Russia could receive a smaller number of North Korean troops for training, logistics, security or selected combat missions.
In this scenario, the 50,000 figure would represent an upper estimate rather than an immediate deployment.
Scenario Two: Large-Scale Reinforcement
If the full number eventually materializes, Russia could gain a substantial new manpower pool.
That could allow Moscow to redistribute Russian troops to other sectors of the front.
Scenario Three: Expanded Military Cooperation
The most consequential possibility could involve more than soldiers.
Russia and North Korea could expand cooperation in missiles, drones, electronic warfare, air defense and military training.
That would make their relationship much more strategically important.
Scenario Four: Wider Regional Consequences
Greater Russian assistance to North Korea could trigger stronger military planning in South Korea, Japan and the United States.
The result could be a feedback loop:
Russia strengthens North Korea → North Korea strengthens its military → South Korea and Japan increase preparedness → regional tensions rise.
The Most Important Question
The central issue is not whether 50,000 North Korean troops will suddenly appear on a battlefield.
The more important question is whether Russia and North Korea are creating a long-term military ecosystem.
If soldiers are exchanged, weapons are supplied, battlefield lessons are shared, missile technology advances and defense cooperation expands, the consequences could last for decades.
A war that began as a conflict between Russia and Ukraine could therefore influence military planning in Europe and Asia simultaneously.
That is what makes the current development so important.
Conclusion
The reported possibility of up to 50,000 North Korean troops being deployed to Russia marks another major development in the growing relationship between Vladimir Putin and Kim Jong Un.
The figure comes from Ukrainian President Volodymyr Zelenskyy and has not been independently verified as the number already deployed.
But the broader trend is clear.
Russia and North Korea have moved far beyond ordinary diplomatic relations.
They now have a formal strategic partnership treaty, military personnel have already been involved in the Ukraine war, North Korean weapons have reportedly appeared on the battlefield, and both countries appear determined to deepen cooperation.
The first North Korean deployment also demonstrated that battlefield experience comes at a high price. Thousands of North Korean troops were estimated to have become casualties during operations in Russia's Kursk region.
Yet the experience itself may be strategically valuable to Pyongyang.
For North Korea, Ukraine can provide lessons in modern warfare.
For Russia, North Korean manpower and weapons can provide additional resources for a prolonged conflict.
And for the rest of the world, the partnership is a reminder that the geopolitical consequences of the Ukraine war extend far beyond Eastern Europe.
The world is not necessarily standing on the edge of a new world war.
But the international security environment is undeniably becoming more interconnected, more militarized and more unpredictable.
The next chapter of the Russia–North Korea partnership could determine whether this cooperation remains a battlefield arrangement—or develops into one of the most consequential military partnerships of the decade.
The real question is no longer whether Putin and Kim are cooperating.
It is how far that cooperation will go.
