Eveline McDermott 21 Jun 2025

In the intricate web of global geopolitics, few relationships are as shrouded in mystery and concern as that between Iran and North Korea. Often perceived as two of the world's most isolated states, their diplomatic and strategic ties have long been a subject of intense scrutiny, particularly for Western intelligence agencies. This enigmatic bond, characterized by mutual defiance against perceived adversaries and a shared pursuit of military self-reliance, holds significant implications for international security and stability.

While official narratives from both Pyongyang and Tehran consistently describe their relations as "positive," the true depth and nature of their cooperation often remain obscured from public view. From historical solidarity forged in the crucible of revolution to contemporary allegations of clandestine military assistance, the dynamic between Iran and North Korea continues to evolve, presenting a complex challenge for global powers seeking to understand and mitigate potential threats.

Historical Foundations of Iran-North Korea Relations

The relationship between Iran and North Korea, or "이란-조선민주주의인민공화국 관계" in Korean and "روابط ایران و کرۀ شمالی" in Persian, has a history rooted in shared anti-imperialist sentiments and a desire for strategic autonomy. Diplomatic relations between the two nations saw a significant improvement following the Iranian Revolution in 1979 and the establishment of an Islamic Republic. This period marked a turning point, as both countries found common ground in their opposition to Western influence, particularly that of the United States.

For decades, the two countries had active diplomatic exchanges, fostering a bond that, while not always overtly public, was consistently described as positive by their official news agencies. This engagement continued even as North Korea sealed its borders in an effort to stave off the pandemic, before a cautious reopening. This historical continuity underscores a deep-seated strategic alignment that transcends immediate geopolitical shifts, laying the groundwork for more covert forms of cooperation.

A Nexus of Concern: Allegations of Military Cooperation

While the official narrative highlights positive diplomatic ties, the real concern for the international community lies in the alleged military cooperation between Iran and North Korea. This aspect of their relationship has often operated "under the radar," even as Iran’s drone exports and North Korea’s artillery shell shipments to the Russian military have been widely discussed. The secrecy surrounding their collaboration fuels speculation and alarm, particularly from intelligence agencies in allied nations.

Recently, South Korea’s spy agency issued a rare warning about cooperation between Iran and North Korea, explicitly stating there is a possibility Pyongyang could have helped Iran in its attack on Israel. This grave assessment suggests a level of military-technical collaboration that extends beyond simple arms trade, potentially involving sensitive technologies or tactical support. Further cementing these concerns, North Korea has reportedly pledged to supply some undisclosed number of military support to Iran in their ongoing battle against Israel. This commitment, if materialized, would significantly alter the dynamics of regional conflicts and global security.

Adding to the evidence of deepening ties, a high-level North Korean delegation led by Yun Jung Ho, North Korea’s Minister of External Economic Relations, flew out for a trip to Iran, as reported by the official Korean Central News Agency. While state media did not immediately provide further details, such visits by senior officials often precede or signify significant agreements, especially in the realm of economic and military cooperation. This visit underscores the continued importance of Iran-North Korea relations in Pyongyang's foreign policy.

The Israel-Gaza Conflict and Pyongyang's Stance

The ongoing war between Iran and Israel is not just affecting the Middle East; its impact is now being felt in other parts of the world, including North Korea. The conflict provides a fertile ground for the Iran-North Korea alliance to demonstrate solidarity and potentially coordinate actions. North Korea's President, Kim Jong Un, has earlier expressed his solidarity with Iran against Israel, signaling a clear alignment in this critical regional confrontation. This public stance, coupled with the reported pledges of military support, indicates a strategic decision by Pyongyang to back Tehran in its conflict with Israel.

Furthermore, North Korea urged Washington to refrain, warning that actions by the US and its allies were pushing the situation in the Middle East to an uncontrollable, catastrophic phase. This statement highlights a shared narrative with Iran, which also frequently criticizes US policies in the region. Such synchronized rhetoric underscores a deeper strategic partnership aimed at undermining US interests and influence globally. Following Israel’s recent airstrike on Iran’s nuclear facilities, North Korean leader Kim Jong Un has also made major moves to boost his country’s weapons production, a development that could be interpreted as a direct response to regional tensions and a signal of continued military self-reliance, potentially bolstered by shared expertise.

Nuclear Ambitions: Parallels and Perils

The specter of nuclear proliferation looms large over the relationship between Iran and North Korea. The advanced state of Iran's nuclear program has raised concerns that the country could become the next North Korea, implying a similar trajectory towards developing nuclear weapons and facing international isolation. Both nations have pursued nuclear programs outside the bounds of international non-proliferation treaties, leading to severe sanctions and global condemnation.

However, the North Korean case also holds lessons that may assist the United States in its use of diplomacy, sanctions, and other tools to prevent Iran from building nuclear weapons or to contain it if it does. The international community has decades of experience dealing with North Korea's nuclear ambitions, offering a playbook, albeit a challenging one, for engaging with Iran. The parallels are striking, from the development of ballistic missile technology to the opaque nature of their nuclear facilities. Any cooperation in this sensitive domain between Iran and North Korea would exponentially increase the global proliferation risk, making this a critical area of concern for intelligence agencies worldwide.

The Economic and Diplomatic Lifeline: China's Role

Despite their defiant postures, both Iran and North Korea face immense international pressure and economic sanctions. In this context, China emerges as a crucial, if often understated, lifeline. The assertion that "Iran, North Korea, and Russia would be very weak and isolated from the world without China’s support" highlights Beijing’s pivotal role. China provides an economic and diplomatic buffer, allowing these states to mitigate the full impact of international isolation.

Beijing’s actual and potential role as a leader in supporting these nations cannot be overstated. While China officially adheres to UN sanctions, its economic engagement and diplomatic backing provide a crucial alternative to Western-dominated global systems. This support allows countries like Iran and North Korea to sustain their regimes and continue their strategic objectives, including military development. The complex interplay of these relationships forms a critical aspect of the evolving global power dynamics, where China’s influence enables the continued defiance of international norms by its partners.

Internal Dynamics: A Tale of Two Regimes

While Iran and North Korea share external strategic alignments, their internal political and social landscapes present stark contrasts. Understanding these differences is crucial for a nuanced view of their bilateral relationship.

Iran's Domestic Challenges

Unlike North Korea, Iran has visible disgruntlement against its rulers that comes to a boil every few years. This internal dissent is a significant factor in Iran's stability and its foreign policy calculations. In 2022, after the regime’s morality police killed a young woman for the purported violation of hijab laws, hundreds of thousands of people took to the streets for weeks in an uprising that shattered the impression of Khamenei’s grip on power. These widespread protests demonstrate a vibrant, albeit suppressed, civil society and a population willing to challenge the regime, distinguishing Iran from the monolithic control seen in Pyongyang.

North Korea's Isolation

In contrast, North Korea maintains an unparalleled level of internal control and isolation. The regime's iron grip on information and movement means that widespread public dissent, as seen in Iran, is virtually non-existent or immediately crushed. This profound difference in internal stability and public expression influences how each country conducts its foreign relations and how it perceives its vulnerabilities and strengths. While Iran must balance external pressures with internal unrest, North Korea operates with a singular focus on regime survival and military advancement, unburdened by significant domestic opposition.

Geopolitical Ramifications and US Interests

The deepening ties between Iran and North Korea, alongside their relationships with other authoritarian states, pose significant challenges to global security and US interests. America’s four great adversaries — China, Iran, North Korea, and Russia — are increasingly acting in unison to undercut US interests, as revealed by the intelligence community. This emerging alignment represents a formidable bloc challenging the existing international order.

The collaboration between these states extends beyond mere diplomatic solidarity; it involves tangible military and economic support that strengthens their collective defiance against Western pressures. This strategic convergence, particularly the growing Iran-North Korea axis, necessitates a re-evaluation of current foreign policy approaches and a more coordinated international response to counter their influence and prevent further destabilization.

The Broader Authoritarian Axis

Despite fears of a North Korean military axis with authoritarian states like China, Russia, and Iran, a 2025 study on global arms proliferation suggested these fears might be "overstated" regarding Pyongyang’s overall military capacity, despite its military support for the war against Ukraine. This study estimated that the DPRK’s nuclear arsenal remained around the same size as the previous year. While this might temper some alarmist views on North Korea's immediate expansion, it does not negate the strategic significance of these alliances. The very existence of such a grouping, even if its military capabilities are debated, represents a significant geopolitical shift, challenging the unipolar moment and fostering a multipolar world order.

The strategic cooperation, whether in sharing military technology, circumventing sanctions, or coordinating diplomatic stances, presents a united front that complicates international efforts to promote stability and non-proliferation. The ongoing war between Iran and Israel, and North Korea's declared solidarity, exemplifies how regional conflicts can become intertwined with broader geopolitical alignments, drawing in distant actors and amplifying global tensions.

Looking Ahead: Diplomacy, Sanctions, and Containment

The complex relationship between Iran and North Korea demands a multi-faceted approach from the international community. The lessons learned from dealing with North Korea’s nuclear program offer valuable insights for managing Iran’s ambitions. The North Korean case also holds lessons that may assist the United States in its use of diplomacy, sanctions, and other tools to prevent Iran from building nuclear weapons or to contain it if it does. This includes a careful balance of coercive measures and diplomatic engagement, recognizing that complete isolation often drives these regimes further into each other's arms.

The challenge lies in crafting policies that effectively deter proliferation and destabilizing actions without inadvertently strengthening the very alliances they seek to disrupt. The future of Iran-North Korea relations will undoubtedly be shaped by regional conflicts, internal pressures, and the evolving roles of major powers like China. Navigating this intricate landscape requires vigilance, strategic foresight, and a nuanced understanding of the motivations and capabilities of all parties involved.

Conclusion

The relationship between Iran and North Korea, while often operating in the shadows, is a critical component of the contemporary geopolitical landscape. From their shared historical grievances against Western dominance to current allegations of military cooperation and nuclear ambitions, the Iran-North Korea nexus presents a persistent challenge to international peace and security. The active diplomatic exchanges, the reported pledges of military support, and the alignment of their stances on critical global conflicts underscore a bond that is both strategic and resilient.

As the world grapples with escalating tensions in the Middle East and the continued proliferation of advanced weaponry, understanding the intricacies of Iran-North Korea relations becomes paramount. Their defiance, often enabled by the crucial support of nations like China, highlights the limitations of traditional diplomatic and sanction-based approaches. Moving forward, a comprehensive strategy that combines targeted sanctions, robust intelligence gathering, and nuanced diplomatic engagement will be essential to mitigate the risks posed by this enduring alliance.
