Iran is facing an unprecedented internal rupture following Supreme Leader Ali Khamenei’s death and intensified actions by the United States and Israel against the Islamic Republic’s military and leadership. What was once a speculative future has become an immediate reality: the regime’s coercive control is fracturing from above, compounded by years of diminishing popular legitimacy from below. This historic moment presents Europe with a critical strategic decision point, moving beyond mere crisis management to actively shaping the profound changes unfolding in Iran.
The Islamic Republic is at its weakest point since 1979, characterized by a complete loss of political legitimacy, economic collapse, and an inability to reform. Four major, increasingly radical anti-regime protest waves since 2017 underscore that internal reform is not feasible. This instability directly impacts Europe, threatening a new wave of asylum seekers driven by economic and political pressures. Furthermore, the economic argument for maintaining ties has vanished; European trade with Iran is marginal, carrying significant risks, and Tehran increasingly aligns economically with Beijing, negating any perceived “values vs. prosperity” trade-off for Brussels.
Conversely, a post-regime Iran presents a significant strategic opportunity for Europe. Iran’s vast oil and gas reserves, currently isolated by ideology, could become a crucial and reliable component of Europe’s diversified energy supply, lessening dependence on Russia. Security implications are equally pressing: the current regime is an active threat on European soil, using intelligence services and the IRGC for surveillance and assassination plots. A new Iranian state, aligned with its people, could dismantle these networks. Moreover, Tehran’s support for Russia’s war in Ukraine highlights how weakening the current regime is integral to broader European security.
Europe must also confront the moral imperative, given the Islamic Republic’s violent crackdown on protestors, which has led to tens of thousands of deaths and imprisonments. The regional destabilization caused by Tehran’s proxy warfare further disrupts trade and inflates costs, reinforcing that stability is incompatible with the current regime. With the United States and Israel actively confronting Tehran, Europe is undeniably part of the evolving security landscape. This necessitates moving beyond managing the current regime to proactively preparing for a post-Islamic Republic era, including engaging with credible political alternatives like Prince Reza Pahlavi, whose secular vision offers a pathway to a democratic, internationally cooperative Iran.
