Executive Summary

This report evaluates the strategic consequences of Iran’s physical geography and the current military conflict involving Israel and the United States.

Although US and Israeli military operations have successfully degraded 80% of Iranian air defences and struck critical industrial sites in Tehran and Isfahan, leading to widespread power outages, the Islamic Republic is still resilient and capable of countering foreign threats.

The analysis focuses on how Iran’s natural defences and control over maritime chokepoints remain central to its survival strategy.

Key Takeaways

• Iran’s mountainous perimeter and central deserts provide significant strategic depth that complicates conventional ground invasions.
• The degradation of the majority of Iran’s air defence systems has left critical nuclear and military sites vulnerable to further aerial raids.
• Control over the Strait of Hormuz remains Iran’s primary economic lever, with ongoing threats to the 20 million barrels of oil transiting daily.
• Diplomatic initiatives by China and Pakistan are emerging as the United States considers targeted ground operations to secure enriched uranium.

Middle East Conflict: Update

The war between the United States, Israel, and Iran has entered its 34^th day following the launch of “Operation Epic Fury,” which began with the assassination of Supreme Leader Ali Khamenei.

President Donald Trump recently addressed the US public, stating that Washington’s objectives are nearing completion but warning of “extremely hard” strikes over the next two to three weeks to force an unconditional surrender.

In response, Iran has intensified its retaliation, launching four waves of ballistic missile attacks against Israel within a single six-hour window today and continuing to disrupt global energy markets by maintaining control over the Strait of Hormuz.

Regional tensions have further escalated as Iranian-backed groups like Hezbollah and the Houthis coordinate strikes on northern and southern Israel, while US allies in the Gulf, such as the UAE and Saudi Arabia, report frequent interceptions of hostile drones and missiles.

Sources within Israel indicate that coordinated airstrikes by Washington and Tel Aviv have significantly degraded Iran’s air defence capabilities, compromising the security of vital nuclear and military installations against subsequent aerial assaults.

Iran’s Geography

Iran occupies a 1.65 million square kilometre landmass at the intersection of West Asia and Central Asia, dominated by a high central plateau. This plateau, sitting between 900 and 1,500 metres above sea level, is enclosed by the Zagros Mountains in the west and south and the Alborz range in the north. These mountain systems form a natural defensive enclosure that protects the country’s core from land-based incursions and conditions its strategic projection.

The interior of the country is defined by the Dasht-e Kavir and Dasht-e Lut deserts, which create an arid and largely impassable core. These geographical features force any invading military movement into predictable and narrow transit corridors, allowing the state to concentrate its limited defensive assets effectively. Historically, this rugged topography has served as a barrier that prevents external powers from easily fragmenting the Iranian state.

On the maritime front, Iran’s southern border provides access to the Persian Gulf and the Gulf of Oman, connected by the Strait of Hormuz. This 33-kilometre-wide chokepoint is a critical global energy hub, through which approximately 25% of the world’s seaborne oil trade transits. Control over this narrow passage allows Iran to exercise significant influence over global energy markets, acting as a “global oil tap” in times of conflict.

Country’s Imperatives and Constraints

Strategic Imperatives:

• Territorial Protection: Utilising the parallel ridges of the Zagros range to force ground forces into costly mountain warfare and preserve the political centre.
• Economic Deterrence: Leveraging the proximity to the Strait of Hormuz to threaten global oil supplies, aiming to deter full-scale military intervention through economic pressure.
• Asset Dispersal: Distributing military and nuclear infrastructure across the vast central plateau and into hardened underground facilities to ensure survival against air campaigns.

Strategic Constraints:

• Air Superiority Deficit: The destruction of 80% of air defences has largely nullified the protection once offered by the mountains against aerial precision strikes.
• Infrastructure Fragility: Concentration of the population in specific valleys makes the state vulnerable to civil unrest if utilities like the power grid are disabled.
• Logistical Inertia: The same mountains that defend the country also hinder internal logistics, making it difficult to rapidly move reinforcements between different territorial compartments.

Why Geographic Features Matter in Iran’s Confrontation with United States and Israel

Geography serves as Iran’s primary defence against ground forces but offers diminishing protection against modern air power. The Zagros Mountains effectively block rapid land offensives, yet the US and Israel have bypassed these barriers through vertical escalation, hitting the Isfahan munitions depot and Tehran’s power substations. Israel’s achievement of “near-total air superiority” has stripped away the natural armour provided by the terrain.

The Strait of Hormuz has become the focal point of Iranian asymmetric retaliation. By striking vessels such as the al-Salmi in Dubai, Iran demonstrates its ability to project power despite losing its air cover. This geographic lever forces the US to consider risky ground operations to secure uranium stocks, as air strikes alone cannot neutralise hardened facilities buried deep within the Iranian Plateau.

Indicators to Monitor

• Strait of Hormuz Transit Volume: Any sustained drop in the 20 million barrels per day flow due to Iranian blockades or strikes.
• Air Defence Reconstitution: Reports of Iranian efforts to repair the radar and missile umbrella over the capital.
• Internal Stability: Escalation of protests following the widespread blackouts in Tehran and other major cities.
• Ground Force Mobilisation: US Pentagon deployments to Kuwait or Iraq indicating a shift toward a land-based intervention.
• Diplomatic Outcomes: The level of international support for the five-point peace plan presented by China and Pakistan.

Outlook

The conflict has entered a phase where Iran’s geographic isolation is being tested by high-technology warfare. While the mountains prevent a swift ground takeover, they cannot prevent the systematic dismantling of industrial and military infrastructure from the air.

If current diplomatic efforts fail, the most likely scenario involves a continued aerial campaign targeting the remaining 20% of Iranian defences, potentially followed by a limited ground incursion into the plateau to secure nuclear materials.
