DECODING: How the West Is Structuring Its Deterrence Against Four Threats

Introduction: four capitals, one shared ambition

Moscow, Beijing, Tehran, and Pyongyang, an axis that is coordinating

The West no longer faces a single isolated threat, but a strategic convergence between four authoritarian regimes: Russia, China, Iran, and North Korea. This reality, long theoretical among defense analysts, materialized abruptly in the fall of 2024, when North Korean troops began fighting directly for Russia on European soil, in Russia's Kursk region, according to the BBC.

This North Korean military presence in Europe, a historic first, led NATO Secretary General Mark Rutte to call the deployment a "tipping point," according to an opinion piece published on NATO's official website. This convergence among authoritarian powers now forces the West to design its deterrence not separately for each theater, European, Indo-Pacific, or Middle Eastern, but as an integrated system against an increasingly coordinated adversarial bloc.

America's national defense strategy confirms this diagnosis

The 2026 National Defense Strategy of the United States, published on January 23, 2026, explicitly identifies Russia, China, Iran, and North Korea as the four principal structural threats the American defense apparatus must address, a strategic framework that now permeates every decision made by NATO and its partners. This official doctrine confirms that decoding Western deterrence can no longer be limited to a single front.

It is this systemic approach that this piece sets out to break down, threat by threat, to understand how the West is building, in this summer of 2026, a coherent response to an authoritarian axis that no longer hides its growing coordination.

It took North Korean troops dying on European soil for the West to finally admit what many analysts had been saying for years: these four regimes are no longer isolated threats, they form a system. Continuing to treat them separately would be a major strategic mistake.

Russia, epicenter of the conflict and laboratory of the authoritarian axis

A war that turned Moscow into a hub

The war Vladimir Putin has waged against Ukraine since 2022 has turned Russia into the hub of an authoritarian support network unlike anything seen since the Cold War. Moscow now receives drones and technical assistance from Iran, troops and munitions from North Korea, and growing economic and diplomatic support from China, forming a triangle of mutual dependencies that did not exist before this invasion.

This Russian dependence on its authoritarian partners, far from being a sign of strength, actually exposes the real limits of Russia's industrial and demographic capacity to sustain a prolonged war of attrition. A country that must import foreign troops to fight on its own occupied soil is not, contrary to Kremlin propaganda, a self-sufficient military power.

The Kursk front, a showcase for this dependence

After Ukraine's August 2024 incursion into Russia's Kursk region, which allowed Kyiv to seize 1,300 square kilometers of territory according to the Kyiv Independent, Moscow had to rely on roughly 12,000 North Korean soldiers to retake control of the region, an implicit admission that the Russian army alone was no longer enough to secure its own national territory against a limited Ukrainian counteroffensive.

This battle for Kursk, however costly it was for Ukraine, revealed to the entire world the true scale of Russia's dependence on its authoritarian allies, a strategic vulnerability the West must fully factor into its long-term deterrence calculus against Putin.

The fact that Putin's Russia had to import thousands of North Korean soldiers to defend its own territory should be enough to demolish the myth of an invincible Russian army. This is the sign of a power running out of breath, not one on the rise.

North Korea, from mercenary soldier to structural partner

Eleven thousand soldiers and a considerable human price

Roughly 11,000 North Korean soldiers were stationed in Russia's Kursk region at the start of 2026, according to South Korean intelligence cited by the Kyiv Independent, including about 10,000 combat troops and 1,000 engineering troops. This presence has come at a considerable human cost for Pyongyang: roughly 6,000 North Korean soldiers have been killed or wounded during offensive operations on Russian soil, according to British intelligence cited in June by the Kyiv Independent.

Despite these massive losses, roughly 1,100 North Korean soldiers who returned home from the front as of December 2025 could be sent back to Russia to continue participating in the war, according to the same South Korean intelligence source. This figure illustrates Kim Jong-un's regime's determination to maintain its military commitment to Moscow, despite the human price already paid by its own troops.

A military cooperation agreement planned through 2031

On April 27, 2026, a Russian delegation traveled to Pyongyang for the inauguration of a memorial complex dedicated to North Korean soldiers who died supporting the Russian invasion of Ukraine, according to The Guardian. Russian Defense Minister Andrey Belousov stated during the visit: "We have agreed with the DPRK's Ministry of Defense to place our military cooperation on a stable and lasting footing." This agreement is expected to run from 2027 to 2031, according to the same remarks reported by The Guardian.

Kim Jong-un himself wrote in a handwritten note left at the memorial that "the spirits of the fallen will remain forever with the great honor they defended," while affirming that his administration "will continue to wholeheartedly support Russia's strategies to preserve its sovereignty, territorial integrity, and security interests." This rhetoric confirms that Pyongyang no longer views its support for Moscow as a one-off, but as a long-term strategic commitment.

A military cooperation agreement running through 2031 between Moscow and Pyongyang is not a minor diplomatic footnote, it is a clear statement of intent: these two regimes are preparing for a prolonged confrontation with the West, not a brief Ukrainian parenthesis that will soon close.

What North Korea concretely gets out of this alliance

Military technology, food, and energy in exchange for soldiers

Analysts cited by The Guardian estimate that North Korea receives, in exchange for its troops and munitions, financial support, military technology, food, and energy resources from Russia. South Korea's National Intelligence Service also confirmed that the North Korean army had acquired modern combat tactics and valuable battlefield data, while modernizing its weapons systems with Russian technical assistance, according to the Kyiv Independent.

This North Korean military modernization, financed indirectly by the blood of its own soldiers on the Ukrainian front, represents a major strategic concern for South Korea, Japan, and all American partners in the Indo-Pacific region, who see Pyongyang acquiring, through this Russian partnership, military capabilities it likely could never have developed alone.

A nuclear-transfer risk that worries experts

Several experts cited by Defense News explicitly worry about a possible "nuclear quid pro quo" in this Russia-North Korea alliance, fearing that Moscow might transfer, in exchange for the blood shed by North Korean soldiers, sensitive technologies related to Pyongyang's ballistic missile or nuclear capabilities. This risk, should it materialize, would durably reshape the balance of deterrence across the entire Indo-Pacific region.

This concern is not baseless speculation: it rests on the very logic of reciprocity that characterizes this alliance, in which every North Korean contribution to the Ukrainian front has historically been matched by a tangible Russian payback. It is this dynamic of strategic bartering that the West must watch with the utmost vigilance in the months ahead.

Every North Korean soldier who dies at Kursk potentially brings Pyongyang one step closer to more advanced nuclear technology. It is a macabre bargain whose full weight the West must grasp before it becomes too late to act against a technologically strengthened North Korea.

China, discreet but strategically decisive partner

Economic support that offsets Western sanctions

Unlike North Korea and Iran, China has not sent troops to fight in Ukraine, but its economic support for Russia remains absolutely decisive to the continuation of the Kremlin's war effort. Chinese purchases of Russian oil, often carried out through channels that skirt Western sanctions, form an essential financial lifeline for Moscow, a role Beijing plays while maintaining an officially neutral diplomatic posture on the conflict.

This Chinese ambiguity, massive economic support combined with a stated diplomatic neutrality, allows Beijing to maximize its strategic gains without directly exposing itself to the harshest Western sanctions, a calculated workaround strategy that illustrates the sophistication of China's approach to this conflict.

Taiwan, the real stakes behind China's observation of the war

Beyond its direct support for Moscow, China is closely watching every aspect of this war to draw lessons applicable to its own ambitions toward Taiwan. How the West supported, or failed to quickly support, Ukraine against the Russian invasion is a precedent Beijing is methodically analyzing to gauge the future credibility of Western guarantees toward other threatened democracies.

It is this dimension of strategic exemplarity that makes China the most structurally significant long-term threat to the West, far more so than Russia itself in terms of overall economic and demographic power, even though Moscow remains the most immediate and deadliest threat on the European battlefield right now.

China isn't firing a single shot in Ukraine, and that is precisely what makes it so dangerous in the long run. Beijing watches, learns, and calculates, while the West focuses on Kyiv's immediate urgency without always seeing the broader lesson China is drawing for Taiwan.

Iran, drone supplier and shadow partner

Shahed drones, Tehran's most visible contribution

Iran provided Russia with the design for its Shahed attack drones, now mass-produced on Russian soil under the name Geran, at a plant in Tatarstan. This Iranian technological contribution allowed Moscow to develop a massive, cheap strike capability against Ukrainian cities, a weapon that has significantly worsened the air-defense crisis documented in Kyiv throughout 2026.

This Iranian-Russian drone cooperation illustrates a two-way technology transfer: while Iran initially supplied the design, Russia subsequently refined and industrialized the technology on a scale Tehran itself had never reached, creating a technological feedback loop that now benefits both regimes simultaneously.

An alliance tested by Iran's own war against Israel

The war between Israel, the United States, and Iran, triggered in late February 2026, has significantly weakened Tehran's ability to keep actively supporting the Russian war effort, its own military stockpiles and strategic attention now absorbed by its direct confrontation with Washington and Jerusalem. This war has also had a paradoxical effect on Ukraine itself, by absorbing part of the American interceptor stockpiles that might otherwise have been redirected to Kyiv.

This interconnection between the Iranian and Ukrainian war theaters perfectly illustrates the systemic nature of the threat the West faces today: every regional conflict involving one of these four authoritarian regimes has direct, measurable repercussions on the other three theaters, a strategic entanglement that considerably complicates any compartmentalized Western response.

Iran's war against Israel unintentionally eased some pressure on American stockpiles meant for Ukraine, but that relief came at the cost of increased munitions consumption elsewhere. It is cruel proof that the West can no longer afford to think about these crises separately.

The authoritarian axis's diplomatic coordination

Military alliances becoming institutionally formalized

Beyond one-off bilateral support, Russia, China, Iran, and North Korea have gradually formalized their alliances through more structured institutional frameworks, from strategic partnership treaties to long-term military cooperation agreements like the one signed between Moscow and Pyongyang for 2027-2031. This growing institutionalization marks a fundamental break from previous decades, when these authoritarian regimes acted far more independently of one another.

This institutional formalization does not, however, amount to a monolithic, perfectly coordinated alliance. Tensions and diverging interests persist among these four regimes, notably between China and Russia over their respective spheres of influence in Central Asia, or between North Korea and China over how far Beijing is willing to go in backing Pyongyang's nuclear ambitions.

A collective threat despite sometimes diverging interests

These internal divergences within the authoritarian axis do not, however, invalidate the reality of the collective threat it poses to the West. Even imperfectly coordinated, these four regimes share one fundamental common interest: weakening the international order Western democracies have led since 1945, each pursuing that goal in its own way and on its own regional strategic timetable.

It is this convergence of interests, more than the existence of a unified command that does not concretely exist, that justifies the West now treating these four threats as an interconnected system rather than four independent geopolitical files managed by separate diplomatic offices.

These four regimes do not necessarily like each other, and their interests often diverge deeply. But their shared contempt for the Western order is enough to bring them close enough together to constitute a systemic threat the West can no longer afford to ignore or compartmentalize.

The Western military response to this convergence

Rearmament designed for several simultaneous theaters

Facing this authoritarian convergence, NATO structured its massive rearmament, documented at the Ankara summit in July 2026, with combined defense spending projected at $1.81 trillion for the year, not solely to respond to the immediate Russian threat in Ukraine, but to prepare for a strategic environment where several theaters could ignite simultaneously, from Eastern Europe to the South China Sea.

This multi-theater planning also explains the announced investment of more than $40 billion in counter-drone capabilities over the next five years, a technology that simultaneously responds to the threat of Iranian Shahed drones used by Russia in Ukraine and to the drone capabilities the Chinese military is actively developing in the Indo-Pacific.

The Patriot license, a symbol of distributed resilience

Trump's promise to grant Ukraine a production license for Patriot interceptors, announced at the Ankara summit, also fits this logic of distributed resilience against a multifaceted authoritarian axis. By diversifying production sites for critical air-defense systems, the West reduces its vulnerability to a production disruption concentrated at a single site, whether caused by sabotage, a cyberattack, or demand saturation linked to several simultaneous conflicts.

This logic of industrial diversification, though its implementation timelines remain long according to experts cited by the Columbian, represents a coherent structural response to a world where Russia, China, Iran, and North Korea could, in a worst-case scenario, seek to simultaneously overwhelm Western defense capabilities on several fronts at once.

Every billion invested in counter-drone capability or in diversifying Patriot production is not just a response to Ukraine, it is an insurance policy against a nightmare scenario in which Moscow, Beijing, Tehran, and Pyongyang would test the West simultaneously on several fronts.

The strategic precedent Ukraine represents for the other three theaters

What Taiwan, Seoul, and Jerusalem are watching closely

How the West honors, or fails to honor within the promised timelines, its commitments to Ukraine is a precedent scrutinized with the utmost attention by Taiwan, South Korea, and Israel, three democracies directly exposed respectively to China, North Korea, and Iran. Every delayed Patriot interceptor delivery to Kyiv sends an unintended but real signal about the future reliability of Western guarantees to these other threatened allies.

This dimension of exemplarity turns the war in Ukraine into a credibility test that extends far beyond its immediate geographic borders. It is precisely this systemic understanding that drives many Western strategists to push for faster, more consistent support for Kyiv, not only for humanitarian or moral reasons, but to preserve the credibility of the entire Western deterrence architecture.

A mirror effect that also works the other way

This exemplarity effect also works in reverse: every documented Ukrainian success, such as the strike campaign against Russian oil refineries or the prolonged resistance to the invasion, demonstrates to authoritarian regimes that their own expansionist ambitions would also run into determined resistance and considerable economic and human cost, a deterrent message that extends far beyond the Russian case alone.

It is this double dynamic, Western credibility on one side and the demonstration of Ukrainian resistance on the other, that gives this conflict its full global strategic reach, far beyond mere immediate territorial considerations between Kyiv and Moscow.

Every day Ukraine successfully resists the Russian invasion is a day Xi Jinping recalculates, a little more, the potential cost of invading Taiwan. This war, which Kyiv never asked for, has become the most important deterrence test of this century.

The structural limits of current Western deterrence

A defense industry that cannot do everything at once

Despite the scale of the budgets announced in Ankara, the Western defense industry remains under production strain facing unprecedented combined demand coming simultaneously from Ukraine, from NATO members' own national needs against the direct Russian threat, and from the growing needs of Israel and Taiwan against their own respective threats. This industrial saturation is the most concrete, most immediate limit on any multi-theater deterrence strategy.

Resolving this saturation will require years of sustained industrial investment, as illustrated by the 18-to-30-month timelines Ukrainian experts cite for Patriot interceptor production alone, a timeline that leaves the West structurally vulnerable in the short term to an authoritarian axis that could seek to exploit this temporary window of industrial weakness.

The risk of democratic fatigue in the face of a long-term effort

Beyond industrial constraints, Western deterrence against these four threats rests on a risky democratic bet: that Western public opinion can sustain a budgetary and military effort across several theaters simultaneously, potentially for several decades, without giving way to fatigue or political polarization that could fracture the strategic unity this effort requires.

It is this democratic bet, more uncertain than any industrial or budgetary calculation, that will ultimately determine whether the structured deterrence doctrine against these four threats documented in this piece can hold for the time needed to effectively deter Moscow, Beijing, Tehran, and Pyongyang simultaneously.

I fear Western democratic fatigue more than any military advance by this authoritarian axis. Putin, Xi, Khamenei, and Kim's regimes have no elections to fear; they can patiently wait for our own internal divisions to do the work for them.

What the North Korean case reveals about the nature of this deterrence

Deterrence that must now cover unprecedented scenarios

The presence of North Korean troops fighting directly on European soil is an unprecedented precedent that forces the West to fundamentally rethink its traditional deterrence scenarios. Until recently, Western defense planning rarely envisioned a scenario where an isolated Asian regime like North Korea would deploy combat forces so far from its own territory, an assumption that has now become a documented, lasting reality.

This new reality requires NATO to incorporate, into its own strategic planning exercises, the possibility that other conflict theaters could also see forces or resources from several authoritarian regimes converge simultaneously, a scenario the post-Cold War Western security architecture had never seriously anticipated at this scale.

An alarm bell for the entire international system

This North Korean precedent also sends a broader alarm to the entire international system built on respect for territorial sovereignty: if a regime as isolated as Pyongyang's can deploy combat troops with impunity in support of a war of aggression waged thousands of kilometers from its own borders, that dangerously erodes the international norms that, in theory, should deter this kind of extraterritorial military intervention.

It is this normative erosion, more insidious than any direct military confrontation, that may be the deepest long-term danger this authoritarian convergence poses to the international order, a danger that extends far beyond the current Ukrainian conflict alone.

That Pyongyang can send soldiers to die in Europe without serious international consequence should terrify any smaller, more vulnerable state around the world. If this impunity persists, which authoritarian regime will hesitate next time before exporting its own violence beyond its borders?

The economic dimension of this four-front deterrence

Western sanctions facing an organized evasion network

The convergence between Russia, China, Iran, and North Korea is not limited to the military domain: it also extends to an economic network of mutual sanctions evasion. Chinese purchases of Russian oil, alternative trade routes developed with Iranian assistance, and North Korean access to Russian energy resources in exchange for troops together form a parallel economic system that reduces the effectiveness of individual Western sanctions.

This economic reality forces the West to also rethink its sanctions strategy, no longer as punitive measures targeting one country at a time, but as a coordinated effort aimed at the entire evasion network now linking these four authoritarian regimes together, a diplomatic and technical task considerably more complex than traditional bilateral sanctions.

Russian oil, a direct economic battleground

It is precisely in this context that Ukraine's campaign of strikes against Russian oil refineries, which by some estimates disabled up to 42.74 percent of Russian refining capacity in early July 2026 according to Al Jazeera, takes on its full expanded strategic meaning. Every barrel of Russian oil that can no longer be sold, notably to China, weakens not only Moscow's direct war effort but also destabilizes the entire economic network sustaining the convergence between these four authoritarian regimes.

This economic dimension of deterrence, often less visible in the media than weapons deliveries, is nonetheless a first-order strategic lever that the West and Ukraine are already actively exploiting, with measurable results documented month after month by independent energy analysts.

Striking a Russian refinery in Siberia is not just a blow against Putin, it is a blow against the entire economic network linking Moscow to Beijing, Tehran, and Pyongyang. Ukraine, without explicitly intending to, is waging an economic war that weakens this entire authoritarian axis.

What this four-front deterrence demands of Western diplomacy

Diplomatic coordination that must match the adversary's military coordination

Facing such an advanced military, technological, and economic convergence among these four authoritarian regimes, the Western response can no longer be limited to a sum of separate bilateral policies toward each of them. It requires stronger transatlantic and Indo-Pacific diplomatic coordination, explicitly linking the Ukrainian, Taiwanese, Korean, and Middle Eastern files into a single coherent doctrine of global deterrence.

This coordination remains, to this day, imperfect and fragmented among different Western administrations and alliances, each retaining its own regional priorities and its own internal political constraints, a lack of overall coherence that authoritarian regimes are actively seeking to exploit by playing on divisions within the Western camp.

The urgency of a truly global doctrine

It is this urgent need for a truly global doctrine, going beyond the traditional silos between European, Indo-Pacific, and Middle Eastern affairs, that should guide upcoming institutional reforms at NATO and among its democratic partners in the months and years ahead, as the convergence between Moscow, Beijing, Tehran, and Pyongyang continues to structure and institutionalize itself.

Without this doctrinal evolution, the West will keep responding to a systemic, coordinated threat with fragmented, siloed responses, a strategic mismatch that could prove costly should one of these four theaters ignite simultaneously with another in the years ahead.

The West still thinks in silos, one team for Russia, one for China, one for Iran, one for North Korea, while these four regimes themselves already think as an integrated system. This coordination gap must be fixed before it becomes our greatest strategic vulnerability.

What Indo-Pacific allies expect from this deterrence

Japan and South Korea, forward sentinels facing Pyongyang and Beijing

Japan and South Korea, two democracies directly exposed both to North Korea's accelerated military modernization through its Russian partnership and to China's rising power, are watching with particular attention how the West is structuring its response to this authoritarian convergence. Both countries have themselves significantly increased their own defense budgets in recent years, a trend that fits the same logic of preventive rearmament seen on the European side and documented in Ankara.

This Indo-Pacific solidarity with the broader Western effort shows how deterrence against these four threats is no longer confined to a classic transatlantic axis, but now extends to a truly global coalition of democracies that share the same concerns about Russia, China, Iran, and North Korea.

A strategic interdependence still insufficiently institutionalized

Despite this obvious convergence of interests, the institutional mechanisms formally linking NATO to its Indo-Pacific partners such as Japan, South Korea, or Australia remain less developed than traditional European collective defense structures, an institutional imbalance that still limits the West's ability to respond in a truly unified way to a crisis affecting several geographically distant theaters at once.

Closing this institutional gap is one of the most urgent projects for the architects of Western security in the years ahead, as the convergence between these four authoritarian regimes continues to demonstrate, precedent after precedent, its truly transregional rather than strictly European or strictly Asian dimension.

Japan and South Korea are no longer simple distant observers of the war in Ukraine, they are drawing direct lessons for their own security against Pyongyang and Beijing. The West must finally build the institutional bridges formally linking these theaters, rather than treating them as separate files managed by different offices.

What this global solidarity concretely changes

This emerging global solidarity is already translating into concrete steps: increased intelligence sharing between Western and Indo-Pacific allies, closer coordination on sanctions targeting the economic evasion networks linking Russia, China, Iran, and North Korea, and increasingly frequent joint military exercises between Western and allied Asian forces.

It is this gradual materialization of a truly global deterrence, still imperfect but steadily improving, that offers the best long-term guarantee against the temptation for any one of these four authoritarian regimes to test Western resolve in isolation on a theater it wrongly judges to be less watched than the others.

I want to believe that this nascent global solidarity between Europe and the Indo-Pacific will, over time, become as solid as the historic transatlantic alliance. It may be the best strategic news of this difficult decade: the isolation of each theater already belongs to the past.

Conclusion: deterrence under construction, not yet complete

What this summer of 2026 makes clear

At the end of this analysis, one conclusion stands clear: the West has indeed begun structuring its deterrence around the explicit recognition of four converging threats, Russia, China, Iran, and North Korea, a doctrinal evolution confirmed both by the American National Defense Strategy of January 2026 and by the scale of the rearmament documented at the NATO summit in Ankara. This strategic awakening, however late according to some analysts, marks a real advance over the more fragmented approach that prevailed before the 2022 Russian invasion.

But this deterrence remains, to this day, a work in progress rather than a fully operational system. The documented industrial bottlenecks in Patriot interceptor production, persistent internal divisions among Western allies, and the risk of democratic fatigue in the face of a very long-term effort are all potential cracks the four converging authoritarian regimes will inevitably seek to exploit.

Ukraine, still at the heart of this global test

Ukraine's fate will continue to function, in the months and years ahead, as the most visible and immediate indicator of how solid this four-front deterrence really is. Every documented Ukrainian success, every Western promise kept within its announced timeline, strengthens the credibility of this entire architecture against Moscow, Beijing, Tehran, and Pyongyang simultaneously.

It is this responsibility, extending far beyond Ukraine's borders alone, that the West must fully embrace in the coming months, aware that the outcome of this war will durably shape the credibility of its deterrence against the entire authoritarian axis now watching, with the closest attention, every one of its decisions.

Columnist's transparency note

What I know and what I don't

I know that roughly 11,000 North Korean soldiers were stationed in Russia's Kursk region at the start of 2026, according to South Korean intelligence cited by the Kyiv Independent. I know that Russia and North Korea concluded a military cooperation agreement planned from 2027 to 2031, according to statements from Russian Defense Minister Andrey Belousov reported by The Guardian. I know that the American National Defense Strategy of January 2026 explicitly identifies these four regimes as top structural threats.

I do not know with certainty whether a nuclear technology transfer has actually taken place between Moscow and Pyongyang in exchange for North Korean military support; in my sources, this concern rests on expert analysis rather than documented factual confirmation. I prefer to flag this clearly rather than present this hypothesis as established fact.

Method

This piece draws on reporting from the Kyiv Independent, The Guardian, the BBC, and Defense News, as well as official documents such as the American 2026 National Defense Strategy and opinion pieces published on NATO's official website, covering the period between 2024 and July 2026. No scene has been invented, and no firsthand testimony is claimed beyond the official statements and intelligence reports cited by these sources.

My editorial angle is explicit: I consider this convergence between Russia, China, Iran, and North Korea a real systemic threat to the Western international order, without presenting this alliance as perfectly unified or free of internal tensions, which my sources also document.
