Geopolitical Analysis of War with Iran and Regime Change

Iranian Regime Weakened: Can it survive?

The Islamic Revolutionary Guard Corps (IRGC) has struggled to maintain its deterrent reputation amid ongoing conflict in the Persian Gulf. Despite continuing attacks on Gulf infrastructure and some resilience, the IRGC has suffered operational losses, damaged logistics and business networks, and apparent fragmentation of command. The wider war’s costs are high—civilian casualties, disrupted energy and trade, and regional economic losses—while U.S. and Israeli aims and strategies remain contested and unclear. It should be noted that wars have a large element of unpredictability and in this case the goal of regime change is elusive. Besides the economic costs of higher oil prices, the war has cost the US well over $11 billion dollars in just a week.

The Iranian regime is getting desperate. After a week of war, Iranian retaliation has dried up numbers wise but has hit vital energy infrastructure in the Gulf plus several oil tankers. The main threat is the closure of the Strait of Hormuz. In short, the US-Israeli attacks have destroyed most of the nuclear facilities, command and control centers, and navy. Importantly, almost all the solid-fuel factories have been destroyed along with the key airport near Tehran used to support Iranian proxies. However, this regime will linger in a weakened state unless a popular uprising is supported by US troops on the ground. Key points:

• Casualties and damage: By March 12, ~1,800 killed in Iran (mostly civilians); at least 30 killed in Israel/Gulf attacks; oil, tourism and trade disrupted; Gulf losing ~$500m/day in revenue.
• Military impact: Pentagon reports thousands of strikes and many Iranian naval losses; Israel claims most of Iran’s missile launchers have been neutralized or buried; IRGC attacks continue but increasingly target soft infrastructure.
• IRGC’s standing weakened: Command appears fragmented, senior commanders killed or hiding, logistics and parts supply (e.g., solid-fuel propellant factories) damaged, and IRGC-linked commercial/networks hit by strikes and sanctions.
• Regional and political fallout: Gulf states seek to reduce dependency on Iran; Dubai/UAE moving to clamp down on Iranian business ties; U.S. political debate about long-term strategy—some warn bombing alone won’t prevent reconstitution.
• Uncertain outcomes: The IRGC may remain politically central but less dominant; conflict could persist in cycles similar to post-1991 Iraq if production and capabilities are repeatedly targeted rather than resolved.

Let’s now take at look at two key goals that the US and Israel need to accomplish in a relatively short time frame of a few weeks if not sooner. First, opening traffic back up in the Strait of Hormuz. Second, eliminating the remaining highly enriched uranium (HEU) stockpiles. Finally, we look at the implications of a long war.

Can the US open up the Strait of Hormuz?

The risks and challenges of using US naval escorts to reopen the Strait of Hormuz after attacks and mine-laying have disrupted tanker traffic during the Operation Epic Fury conflict is difficult. Escorting convoys would be difficult, costly, and could expose American ships to missiles, drones, fast attack boats and mines. Historical parallels (Dardanelles, 1915; Operation Earnest Will, 1980s) and expert views suggest layered Iranian defences and confined geography favor the defender, so clearing the strait is unlikely to be quick or risk-free.

Iran has escalated attacks in the Gulf and threatened future strikes on U.S. bases and ships after the killing of its previous leader. Iranian forces have targeted commercial shipping in the Strait of Hormuz and nearby ports, prompting international concern about energy supply and security. The U.S. and Israel continue operations against Iranian-linked targets, while the International Energy Agency agreed to release reserves to stabilize markets.

Iran’s new supreme leader, Mojtaba Khamenei, vowed retaliation and continued disruption of the Strait of Hormuz; Iranian forces struck commercial vessels (including a Thai-flagged bulk carrier) and targeted Iraqi ports. Tehran warned U.S. bases across the Middle East would be attacked; U.S. Central Command says U.S. forces have struck roughly 6,000 Iranian targets since the conflict began.

In response, global energy markets felt the pressure: the IEA approved releasing 400 million barrels from strategic reserves; Iranian officials warned oil could hit $200/barrel but Western bodies signaled limited near-term supply panic.

In addition, there are regional spillovers: Qatar and Saudi Arabia reported thwarted missile/drone attacks; Israel struck alleged Hezbollah sites in Lebanon, triggering new travel advisories. Key points:

• Attacks and mines have sharply reduced tanker transits through the Strait of Hormuz, creating energy-market shocks; some countries discuss sending escorts.
• Iran’s threats include ballistic/cruise missiles, drones, fast attack boats and large numbers of sea mines and unmanned underwater vehicles.
• US military leaders express caution: escorts would need extensive air and sea surveillance and mine-countermeasure capabilities, and current assets may be tied to other tasks.
• Historical examples (Operation Earnest Will; Gallipoli/Dardanelles) warn that reopening a narrow, defended strait can be protracted and costly.
• Even with technological advantages, confined waters blunt those benefits and clearing layered defences (missiles, drones, boats, mines) is complex and dangerous.

Eliminating the Remaining Iranian Nuclear Threat

removing Iran’s nuclear threat by force is possible, it is risky and could backfire—encouraging proliferation, leaving enriched uranium unsecured, or provoking prolonged conflict. The three U.S. options are: a risky special-forces seizure of fissile material; repeated bombing to delay the programme (costly and unsustainable); or negotiating a deal to halt enrichment and remove HEU. Despite the regime’s untrustworthiness and the moral compromises involved, a negotiated settlement tied to sanctions relief is presented as the least bad and most feasible choice. Summary:

• Iran’s regime seeks a nuclear threshold and may accept great risks to achieve or retain it; post‑war instability could scatter about ~400 kg of HEU, enough for multiple bombs.
• Seizing fissile material by force is feasible but highly demanding, dangerous, and uncertain.
• Continued bombing to suppress the programme would be costly, provoke regional disruption, and is politically unsustainable for the U.S.
• A negotiated deal—ending enrichment, intrusive monitoring, and removal/dilution of HEU in exchange for sanctions relief—is odious and uncertain but likely the best option to reduce long-term risk.
• Past diplomacy (2015 deal) shows limits and fragility, but given the alternatives it remains the most pragmatic path.

Regime Survival and the Risks of a Forever War

The U.S. (under Trump) may achieve a tactical military victory over Iran — destroying much of its military infrastructure — that will not translate into a durable political outcome. The Iranian regime would likely survive, adapt, and foster long-term resentment that fuels recurring violence, proxy attacks, and potentially renewed terrorism. Historical lessons show overwhelming military force and strategic bombing often harden resistance rather than produce political collapse. The region’s security balance, Gulf states’ defenses, U.S. commitments, and prospects for Iranian domestic change will shape a costly, uncertain aftermath.

The US and Israeli strategy seems to be to weaken the Iranian regimes infrastructure to the point that it cannot govern and will eventually implode. The question is how likely is that to happen. Key points:

• A short-term U.S./Western military victory could severely degrade Iran’s military and nuclear capabilities but probably won’t topple the regime.
• Military success rarely equals political victory; bombing and destruction often strengthen resolve and prolong conflict (“mowing the grass” dynamic).
• Iran’s leadership and institutions can be replaced or adapt; popular uprisings are uncertain and repression or regime resiliency can persist.
• Consequences include hardened regional tensions, stronger defenses by Gulf states, expensive prolonged U.S. military commitments, and heightened risk of retaliatory or clandestine terrorism.
• Long-term stability will require political strategies to support Iranian civil society and constructive diplomatic engagement, not only kinetic measures.
