The Implications of Iran's Regime Collapse: A Deep-Dive Analysis

The recent U.S.-Israeli military campaign against Iran, initiated on February 28, 2026, aims to weaken the Iranian regime significantly, with the potential for regime collapse. This operation has raised concerns about the broader implications for regional stability, particularly regarding a possible refugee crisis in Europe and the emergence of new militant threats.

The military strikes, which resulted in the death of Iran's Supreme Leader Ayatollah Ali Khamenei, are part of a long-standing strategy by U.S. President Donald Trump and Israeli Prime Minister Benjamin Netanyahu to destabilize Iran. Both leaders have expressed intentions to dismantle Iran's nuclear capabilities and military strength. The campaign has included targeted strikes on key Iranian military and internal security structures, aiming to create conditions for internal opposition to flourish.

Amos Yadlin, former head of Israeli military intelligence, noted that the goal of the strikes is to create conditions for the Iranian populace to replace the current regime. However, he acknowledged that the regime remains resilient, with no clear alternative leadership emerging. The Iranian Revolutionary Guards Corps (IRGC) maintains a substantial military presence, estimated at around one million soldiers, complicating any potential regime change.

Critics of the military campaign warn that the strategy could lead to a chaotic power vacuum in Iran, reminiscent of the aftermath of the Iraq War. Experts like Mark Cancian and Mick Mulroy have highlighted the risks of creating a dysfunctional state, which could foster civil unrest and allow terrorist groups to exploit the situation. The lack of a unified opposition within Iran further complicates the prospect of a smooth transition to a stable government.

The potential collapse of the Iranian regime could trigger an unprecedented refugee crisis, with migration watchdogs predicting that even a partial destabilization could lead to millions fleeing to Europe. The EU Agency for Asylum has warned that a 10% displacement of Iran's population could rival the largest refugee flows seen in recent decades. Additionally, a power vacuum in Iran could provide a safe haven for militant groups, posing new security threats to Western nations.

While some analysts assert that the Iranian regime is on the brink of collapse, others, including Israeli security sources, maintain that it continues to function despite significant losses. This discrepancy highlights the uncertainty surrounding the regime's resilience and the potential for internal power struggles as the military campaign progresses.

As the military campaign unfolds, the immediate future of Iran remains uncertain. Experts suggest that the most likely outcome may be a regime adjustment rather than a complete collapse. Figures such as Ali Larijani may emerge as temporary leaders, but the potential for a civilian uprising remains a critical concern. The international community, particularly Europe, faces a pivotal choice: to engage actively in shaping Iran's future or to remain passive, risking further chaos.

• “If the ultimate objective is regime collapse, there must be a plan to replace and stabilise the country immediately thereafter. If a vacuum is left, it could result in an ungoverned space that terrorist groups may take advantage of as they did in Syria.” — Mick Mulroy, Former Senior U.S. Defense Official
