How Iran and Its Allies Reshaped the Middle East War

The landmark memorandum of understanding signed between the United States and Iran has officially halted more than three months of direct warfare, according to reports published by Al Jazeera. The agreement alters the geopolitical landscape of the Middle East by lifting a United States naval blockade and establishing a $300bn reconstruction fund for Iran, while effectively abandoning Washington’s initial war aim of regime change.

Strategic Impact on Iran’s Proxy Network

The prolonged conflict has imposed a severe stress test on Iran’s regional network of allied forces, known as the axis of resistance, which includes Lebanon’s Hezbollah, Yemen’s Houthis, and various armed groups in Iraq. For decades, Tehran relied on these forward-defense allies to keep conflicts away from its borders. However, during the recent US-Israeli war, when Iran’s own territory and military infrastructure were directly at stake, Tehran chose to rely primarily on its own missiles, drones, and control over the Strait of Hormuz rather than unleashing the full operational force of its proxies.

Peter Salisbury, a professor at Columbia University’s School of International and Public Affairs, spoke with NPR’s Rob Schmitz regarding how Iran and its regional allies have fundamentally reshaped the trajectory of the war. Analysts evaluating the conflict note that groups like the Houthis acted with distinct caution during periods when they possessed the tactical capacity to open new regional fronts.

This restraint has fueled an intense debate among international relations scholars regarding whether Iran’s regional deterrence has suffered permanent degradation or is simply mutating. Nader Hashemi, a professor of Middle East politics at Georgetown University, argues that the war exposed a significant weakening of Iran’s regional doctrine, stating that the axis is currently at its weakest point since formation.

Conversely, Negar Mortazavi, a senior fellow at the Center for International Policy, characterizes the shift as a necessary strategic adaptation. According to Mortazavi, the conflict exposed the limits of forward defense while accelerating a definitive transition toward homeland-based deterrence anchored by long-range missiles and asymmetric maritime choke points.
