A Shifting Landscape: The EU-Iran Relationship

The relationship between the European Union and Iran has undergone significant transformations, marked by periods of intense diplomatic engagement and severe strain. At its core, the EU's approach to Iran is multifaceted, balancing concerns over human rights, nuclear proliferation, and regional stability with a persistent belief in the power of diplomacy. This delicate balance is often challenged by Iran's actions, which frequently trigger strong responses from Brussels. The EU's engagement is coordinated by a division of the European External Action Service (EEAS), a structure established after the conclusion of the Joint Comprehensive Plan of Action (JCPOA) in 2015, signaling a period of intensified focus on Iran. Historically, relations between the European Union and Iran reached a peak in 2015 with the conclusion of the nuclear deal (JCPOA). This landmark agreement, involving Russia, China, the US, the E3 (France, Germany, and the United Kingdom), and Iran, was capably facilitated by the EU External Action Service, which managed to navigate complex negotiations without losing sight of the interests of its larger member states. The JCPOA represented a moment of optimism, where a comprehensive diplomatic solution seemed possible for one of the world's most pressing nuclear concerns. However, this peak was followed by a period of decline, particularly after the US withdrawal from the agreement, which complicated the EU's efforts to maintain the deal. The current state of EU-Iran relations is characterized by deep concern and the imposition of sanctions. The EU has imposed sanctions against Iran in response to a range of critical issues, including its human rights abuses, nuclear proliferation activities, and, more recently, its military support for Russia's war of aggression against Ukraine. These sanctions reflect the EU's commitment to upholding international law and promoting its core values, even when faced with complex geopolitical challenges. The ongoing tension underscores the need for a carefully calibrated approach from EU member states, one that is firmly based on established European interests.

Sanctions as a Tool: Addressing Core Concerns

Sanctions have become a primary instrument in the European Union's foreign policy toolkit regarding Iran. These measures are not arbitrary but are a direct response to specific actions by the Iranian regime that are deemed to violate international norms or threaten regional and global security. The EU's sanctions regime against Iran targets a range of issues, reflecting the depth and breadth of its concerns.

Human Rights and Repression

A significant driver of EU sanctions against Iran is the ongoing repression and human rights violations within the country. The EU is deeply concerned by Iran’s distressing practice of arbitrarily detaining EU mono and dual nationals on spurious grounds, often with a view to making political gains. This practice not only violates international law but also directly impacts EU citizens and their families. Beyond this, the broader human rights situation in Iran is a constant source of alarm for the EU. There has been a dramatic increase in the number of executions, including of women and individuals belonging to ethnic and religious minorities, highlighting a severe regression in human rights standards. The EU's consistent condemnation and imposition of sanctions in this area underscore its commitment to universal human rights principles.

Nuclear Proliferation and the JCPOA

Iran’s nuclear program remains a central concern for the EU. Since 2006, the EU High Representative has led diplomatic efforts between the E3/EU+3 (China, France, Germany, Russia, the United Kingdom, and the United States) and Iran, which culminated in the conclusion of the Joint Comprehensive Plan of Action (JCPOA) on Iran’s nuclear program in Vienna on 14 July 2015. France, Germany, and the EU are signatories to this nuclear control agreement with Iran and have long held the belief that the deal is the only means to restrict Iran’s nuclear weapons capabilities. The EU believes that without any question, Iran shouldn’t have nuclear weapons. Despite the challenges, including the US withdrawal, the EU has consistently worked to preserve the JCPOA, viewing it as a critical non-proliferation achievement. However, Iran's continued advancements in its nuclear program beyond JCPOA limits have led to renewed EU concerns and discussions about potential responses.

Military Support for Russia

A more recent, but equally grave, concern that has prompted EU sanctions is Iran’s military support for Russia’s war of aggression against Ukraine. The EU has strongly condemned Iran’s supply of ballistic missiles and drones to Russia. The European Union agreed on Monday to impose sanctions on seven people and seven organizations, including airline Iran Air, for their links to Iranian transfers of ballistic missiles to Russia. This decision followed an indication by the European Council in March 2024 that, were Iran to transfer ballistic missiles and related technology to Russia for use against Ukraine, the EU would be prepared to respond swiftly, including with new sanctions. The EU Foreign Affairs Council on 14 October saw the first tightening of sanctions against Iran, which included three Iranian airlines, among them national airline Iran Air. This specific targeting highlights the EU's resolve to counter actions that undermine international peace and security.

Diplomatic Endeavors: A Contrasting Approach

Despite the imposition of sanctions and deep concerns, diplomacy remains a cornerstone of the European Union's strategy towards Iran. The EU consistently advocates for dialogue and negotiation as the preferred path to resolving complex issues, even when faced with significant provocations. This diplomatic push often stands in stark contrast to the approaches taken by other major global players.

EU's Persistent Engagement

The EU's commitment to diplomacy is evident in its continuous efforts to engage with Iranian officials. Iran's foreign minister, Abbas Araghchi, has been meeting with his European counterparts from Britain, Germany, and France, along with the European Union's High Representative, Kaja Kallas, for discussions. These meetings underscore the EU's belief that open channels of communication are vital, even amidst severe disagreements. EU chief Ursula von der Leyen, while blaming Iran for conflict, has also stated that she told Israeli Prime Minister Netanyahu that diplomacy is the "best solution." This nuanced stance reflects the EU's dual approach of condemning problematic actions while keeping the door open for negotiated outcomes. Iran itself has indicated a readiness to consider diplomacy once aggression is stopped, as stated by its foreign minister following talks with some of his European counterparts. This suggests a mutual, albeit often strained, recognition of diplomacy's role.

Divergence from US Policy

Europe’s push for diplomacy is in sharp contrast to messages from Washington, particularly during certain US administrations. For instance, former U.S. President Donald Trump openly weighed bombing Iran and called for the unconditional surrender of the Iranian leadership. Such hawkish rhetoric and maximalist demands differ significantly from the EU's more measured and multilateral approach, which prioritizes de-escalation and the preservation of diplomatic frameworks like the JCPOA. While the EU shares many of the US's concerns regarding Iran, its preferred methods for addressing these concerns often diverge, reflecting different strategic philosophies and a greater emphasis on soft power and multilateral institutions.

EU's Institutional Framework for Iran Relations

The European Union's engagement with Iran is not ad-hoc but is structured through established institutional mechanisms. The EU does not currently have a delegation in Iran, which can complicate direct, on-the-ground engagement. However, the coordination of the EU's relations with Iran falls under a dedicated division of the European External Action Service (EEAS). This division was specifically established after the conclusion of the JCPOA in 2015, highlighting the increased strategic importance placed on managing the EU-Iran relationship post-nuclear deal. The EEAS plays a crucial role in facilitating diplomatic efforts, coordinating policy responses among member states, and ensuring a coherent EU stance on complex issues ranging from nuclear non-proliferation to human rights. This institutional framework underscores the EU's long-term commitment to a structured engagement with Iran, despite the inherent challenges.

Geopolitical Proximity: Iran as a Future EU Neighbor

An often-overlooked aspect of the EU-Iran relationship is the potential for increased geographical proximity. Should Armenia, which is planning to apply for EU membership, and Turkey, which is a candidate for EU membership, accede to the EU, Iran will become a direct border neighbor with the European Union. This prospective geopolitical shift has significant implications for future EU-Iran relations. Direct bordering would necessitate even greater cooperation on issues such as border security, migration, and trade, potentially transforming the dynamics of engagement. It would also bring the complexities of Iran's internal and regional policies even closer to the EU's immediate sphere of influence, requiring more intensive and nuanced diplomatic strategies. This future scenario underscores the long-term strategic importance of Iran to the EU's broader neighborhood policy and security interests.

Arbitrary Detentions and Human Rights Alarms

The human rights situation in Iran remains a profound and persistent concern for the European Union, casting a long shadow over any attempts at broader cooperation. The EU's deep concern is frequently voiced regarding specific, egregious practices by the Iranian authorities.

Concerns Over EU Nationals

A particularly distressing practice for the European Union is Iran’s arbitrary detention of EU mono and dual nationals. These detentions are often carried out on spurious grounds, and the EU suspects they are primarily used with a view to making political gains. This "hostage diplomacy" tactic is a direct affront to international law and creates immense distress for the individuals involved and their families, severely straining trust and diplomatic relations between the EU and Iran. The EU consistently calls for the immediate and unconditional release of these individuals, emphasizing that their detention is unacceptable and undermines any prospects for constructive dialogue.

Escalating Executions

Beyond the issue of arbitrary detentions, the broader human rights landscape in Iran is deteriorating, marked by a dramatic increase in the number of executions last year. This alarming trend includes the execution of women and individuals belonging to ethnic and religious minorities, highlighting a systemic disregard for fundamental human rights and due process. The EU has repeatedly condemned these practices, viewing them as a clear violation of international human rights obligations. The rising number of executions, coupled with the repression of civil society and political dissent, serves as a constant reminder of the profound challenges inherent in the EU's efforts to promote human rights and democratic values in its engagement with Iran.

The Israel-Iran Dynamic and EU's Stance

The escalating hostilities between Israel and Iran present another complex layer to the EU's foreign policy challenges. The EU finds itself navigating a delicate balance, with varying perspectives among its member states. Not all EU countries believe Israel’s attack on Iran is legal under international law, and these differences were on display when ambassadors met in Brussels ahead of a summit. This divergence of views within the EU highlights the difficulty of forging a unified response to a highly volatile regional conflict. Moreover, the broader context of the Israeli-Palestinian conflict is often brought into discussions concerning the Israel-Iran dynamic. Some voices within the EU sphere argue that foreign ministers shouldn’t let the escalating hostilities between Israel and Iran take focus away from the ongoing extermination and apartheid against the Palestinians. This perspective underscores the interconnectedness of regional issues and the need for the EU to maintain a comprehensive and principled approach to peace and human rights across the Middle East, ensuring that one crisis does not overshadow another equally critical concern. The EU's challenge is to address both the immediate threats posed by the Iran-Israel tensions and the underlying, long-standing conflicts in the region.

Recalibrating the Future: EU's Strategic Imperatives

Given the persistent challenges and evolving geopolitical landscape, EU member states need to urgently recalibrate their approach toward Iran. This recalibration must be firmly based on established European interests, moving beyond reactive measures to a more proactive and coherent strategy. The EU's strategic imperatives for its relationship with Iran can be broadly categorized into three main tracks.

Containing the Regime and Supporting Civil Society

The first track involves containing the Iranian regime more forcefully in its conventional activities. This includes robust responses to Iran's destabilizing actions in the region, its missile and drone proliferation, and its military support for aggressive conflicts. The council adopted restrictive measures against seven individuals and seven entities following Iran’s missile and drone transfers to Russia, signaling a willingness to act decisively. This containment strategy aims to limit Iran's capacity to undermine regional security and international norms. The second crucial track is supporting Iranian civil society in its own right and as an investment into the future. Recognizing the aspirations of the Iranian people for greater freedoms and a more open society, the EU should bolster initiatives that empower civil society organizations, human rights defenders, and independent media. This support is not merely an act of solidarity but a strategic investment, acknowledging that a more democratic and rights-respecting Iran would ultimately be a more stable and constructive partner for the EU. It involves a long-term perspective, understanding that fundamental change often comes from within. Finally, the third track involves engaging Iran’s Arab neighbors with a view to sparking discussions on regional security and stability. Fostering dialogue and de-escalation between Iran and its regional counterparts is vital for reducing tensions and preventing wider conflicts. The EU can play a crucial role as a facilitator, encouraging confidence-building measures and promoting frameworks for regional cooperation that address shared security concerns. This comprehensive approach, encompassing containment, support for civil society, and regional engagement, offers a pathway for the EU to navigate the complexities of its relationship with Iran more effectively and in line with its core values and strategic interests.

Conclusion

The relationship between the European Union and Iran is undeniably one of the most intricate and challenging in contemporary geopolitics. Marked by a cycle of diplomatic efforts, the imposition of sanctions in response to human rights abuses, nuclear proliferation concerns, and military support for Russia, it reflects the EU's commitment to its values and international law. From the hopeful peak of the JCPOA to the current climate of deep concern over arbitrary detentions and escalating executions, the EU's engagement remains a delicate balancing act. As Iran potentially becomes a direct neighbor to the EU, and as regional dynamics continue to shift, the imperative for a recalibrated and comprehensive EU strategy is clearer than ever. This strategy must blend firm containment of destabilizing actions with unwavering support for Iranian civil society and proactive engagement with Iran's regional neighbors. The EU's persistent belief in diplomacy, even amidst stark differences, offers a glimmer of hope for future stability.
