Key takeaways
- Afshon Ostovar argues a plausible external regime-change pathway would require an outside military to seize key institutions, neutralize leadership, and control telecommunications to enable a new governing authority.
- Sanam Vakil argues the UAE has been reluctant to freeze Iranian assets because doing so would undermine the UAE safe-haven model and set an unwanted precedent, despite the UAE being a key sanctions-era economic conduit for Iran.
- Afshon Ostovar flags a potential ideological shift where the regime leans more on Iranian nationalism than pan-Islamism to broaden legitimacy, especially among younger security elites.
- Sanam Vakil argues Gulf states fear a postwar scenario in which a weakened Islamic Republic festers under sanctions or collapses into internal conflict, producing humanitarian and economic spillovers analogous to Iraq in the 1990s or Libya after 2011.
- Sanam Vakil argues Iran seeks to end the war only with guarantees, and Gulf-Iranian relations will be badly broken afterward.

Regime Change Feasibility: Opposition Fragmentation And High Bar For Transition
- Afshon Ostovar argues a plausible external regime-change pathway would require an outside military to seize key institutions, neutralize leadership, and control telecommunications to enable a new governing authority.
- Afshon Ostovar argues that in wartime conditions the Iranian protest movement is unlikely to achieve regime change because it is leaderless, lacks a clear takeover plan, and would be rapidly crushed by security forces.
- Afshon Ostovar argues a plausible internal regime-change pathway would be a coup where elements of the security forces turn against top leadership and coordinate with or invite popular mobilization.
- Sanam Vakil assesses Iran's opposition remains divided and insufficiently organized, and that the war has moved faster than opposition groups and the public were prepared for.
- Sanam Vakil observes only limited bridge-building among Kurdish opposition groups while monarchists aligned with Reza Pahlavi and the Mujahideen-e Khalq operate separately.
- Sanam Vakil assesses the Islamic Republic views the war as existential, maintains a monopoly on violence, and will do what it can to stay united and survive.
Gulf Security Constraints: Defensive Depletion, Energy Disruption, And Alliance Management
- Sanam Vakil argues the UAE has been reluctant to freeze Iranian assets because doing so would undermine the UAE safe-haven model and set an unwanted precedent, despite the UAE being a key sanctions-era economic conduit for Iran.
- Sanam Vakil argues Gulf governments are trying to avoid being seen as supporting Israel offensively because they view both Iran and Israel as destabilizing actors and fear blowback.
- Sanam Vakil states Gulf states lobbied President Trump to avoid war and were surprised by the persistence and scale of Iran's retaliation, which compromised Gulf safe-haven reputations.
- Sanam Vakil states Bahrain, Kuwait, and Qatar invoked force majeure on some energy exports amid war-related disruptions and Strait of Hormuz shipping constraints.
- Sanam Vakil argues Gulf states feel the United States prioritized Israel's defense and left the Gulf comparatively exposed, prompting Europe and the UK to step up defensive support.
- Sanam Vakil argues that despite strong defensive performance, Gulf states are worried about interceptor stock depletion and longer-term economic disruption as the war drags on.
Regime Power Center: Irgc Primacy And Post-Succession Governance
- Afshon Ostovar flags a potential ideological shift where the regime leans more on Iranian nationalism than pan-Islamism to broaden legitimacy, especially among younger security elites.
- Afshon Ostovar argues the IRGC backed Mojtaba Khamenei because it views him as a status-quo candidate who will preserve IRGC interests after the Supreme Leader's death.
- Afshon Ostovar argues the Supreme Leader's real power base depends on IRGC loyalty because religious authority is not broadly meaningful among most Iranians.
- Afshon Ostovar expects no new Supreme Leader will quickly consolidate Ali Khamenei's level of personal control because that authority required a long process of building institutional ties and a cult of personality.
- Afshon Ostovar argues Iran is moving toward a military-dominated authoritarian model where the Supreme Leader functions more as a symbolic facilitator than a check on IRGC influence.
Postwar Risk: Weakened-But-Surviving Iran And Asymmetric Retaliation
- Sanam Vakil argues Gulf states fear a postwar scenario in which a weakened Islamic Republic festers under sanctions or collapses into internal conflict, producing humanitarian and economic spillovers analogous to Iraq in the 1990s or Libya after 2011.
- Sanam Vakil argues that if Iran remains heavily sanctioned without rehabilitation or a trade lifeline, economic strain could fuel internal unrest that may arise organically or be externally instigated.
- Afshon Ostovar expects that if the Iranian regime survives intact but is militarily degraded and impoverished, it is likely to become more dangerous and may pursue revenge-driven covert action or terrorism.
- Sanam Vakil argues Gulf states are most concerned about a postwar scenario where the United States ends the conflict and leaves a weakened Islamic Republic that persists and destabilizes the region over time.
War-Termination Bargaining Via Guarantees And Cost-Imposition
- Sanam Vakil argues Iran seeks to end the war only with guarantees, and Gulf-Iranian relations will be badly broken afterward.
- Sanam Vakil argues Iran is trying to spread war costs beyond Iran to create broader economic pain, while seeking an end to the war with guarantees rather than a simple ceasefire.
- Sanam Vakil expects postwar Gulf-Iran relations to be severely damaged, making a return to the prewar normalization trajectory with Saudi Arabia and the UAE difficult.
Watchlist
- Afshon Ostovar flags a potential ideological shift where the regime leans more on Iranian nationalism than pan-Islamism to broaden legitimacy, especially among younger security elites.
- Sanam Vakil argues Gulf states fear a postwar scenario in which a weakened Islamic Republic festers under sanctions or collapses into internal conflict, producing humanitarian and economic spillovers analogous to Iraq in the 1990s or Libya after 2011.
- Public and elite debate in the Gulf is increasingly questioning whether U.S. bases actually insulate Gulf states from strikes and may instead increase blowback risk.
Unknowns
- What specific guarantees (security, sanctions relief, non-aggression, verification mechanisms) are being demanded as a condition for ending the war, and which parties could credibly underwrite them?
- What are the actual interceptor stock levels, resupply timelines, and any rationing/prioritization policies across Gulf air defenses?
- Which energy exports were impacted by the reported force majeure declarations, for how long, and how directly were the disruptions attributable to Hormuz constraints versus other operational factors?
- How cohesive is the IRGC across factions, and are there observable fault lines that would materially alter succession outcomes or create coup risk?
- Is there verifiable evidence of a shift in official ideology toward Iranian nationalism (symbols, curricula, elite rhetoric), and does it change foreign policy narratives or recruitment?
