Iran and the Remaking of the Middle East

The region’s recent history — premature victory claims after the Iraq war, the false dawn of the Arab uprisings, the presumed permanence of the 2015 nuclear deal — counsels against betting too heavily on finality. Iran’s system has absorbed severe shocks before.

For most of the last two decades, no single state has shaped the Middle East’s political fortunes as consistently, or as controversially, as Iran. Any fair account of that role has to steer between two convenient stories. One, favoured in Israel and most Gulf capitals, casts Iran as a relentless aggressor bent on regional domination. The other, closer to Tehran’s own telling, presents Iran as a besieged revolutionary state defending itself against imposed isolation. Both contain truth; both leave out a great deal.

Iran’s regional posture has deep roots. The 1979 revolution left behind a theocratic republic deeply suspicious of Western power, a suspicion sharpened by memories of foreign interference and by the Iran–Iraq War of the 1980s, when Gulf states, the Soviet Union and much of the West backed Baghdad. Out of that experience came a doctrine of “forward defence”: rather than wait to be attacked at home, Iran would contest its adversaries abroad, through allied armed groups rather than head-on military competition it could not win.

The 2003 American invasion of Iraq, intended in part to contain Iran, did the opposite. It removed Tehran’s principal rival, Saddam Hussein, and opened Iraqi politics to Iranian influence. Over the following decade, Iran built what came to be called the Axis of Resistance — Hezbollah in Lebanon, Shia militias in Iraq, the Houthis in Yemen, and various Palestinian factions — with Syria under Bashar al-Assad serving as the connective corridor. It is worth noting, and often overlooked, that many of these partners are not simple proxies taking orders from Tehran; Hezbollah is embedded in Lebanese domestic politics, and the Houthis pursue their own tribal and religious agenda. The network functions on a spectrum from tight control to loose alignment.

Running alongside this has been Iran’s nuclear programme, the source of two decades of sanctions, diplomacy and suspicion. The 2015 nuclear deal capped Iranian enrichment in exchange for relief from sanctions; Washington’s withdrawal in 2018 unravelled it, and repeated attempts at a successor agreement, including talks mediated by Oman as recently as early 2026, have failed. Whether Iran ultimately sought a weapon or, as it insists, only civilian energy and medical isotopes, is a question that even Western intelligence agencies have answered inconsistently. That dispute became the proximate cause of direct war.

Iran’s rivalry with Saudi Arabia, often described in the press as ancient Sunni-Shia hatred, is better understood as a modern contest for regional leadership that has made use of sectarian identity rather than being caused by it. The two countries’ 2023 rapprochement, brokered by China, showed that this rivalry was never fixed — a sign, too, of Washington’s declining monopoly as regional power-broker.

What has followed since 2024 amounts to the most severe setback to Iran’s regional strategy since the revolution. Direct missile exchanges with Israel in April and October 2024 exposed gaps in Iran’s air defences. Israel’s campaign against Hezbollah’s leadership that autumn helped clear the way for the rebel offensive that toppled Assad in December, severing the land route linking Tehran to Beirut. In June 2025, a twelve-day war saw Israel strike Iranian nuclear and military targets before the United States joined with strikes on the underground facilities at Fordow, Natanz and Isfahan — the first direct American attack on Iran’s nuclear programme. American intelligence agencies themselves disagreed sharply over how much damage was done.

The economic fallout — a collapsing currency and fresh sanctions — fed protests that spread across Iran from December 2025 into January 2026, even as security forces held firm. Talks collapsed again in February, and on 28 February 2026 the United States and Israel launched a far larger campaign, this time explicitly framed by Washington as aiming at regime change as well as nonproliferation. Supreme Leader Ali Khamenei was killed in the opening strikes after thirty-six years in power. Days later, Iran’s Assembly of Experts named his son, Mojtaba Khamenei, as his successor — a dynastic transition that sits uneasily with a revolution founded on rejecting hereditary rule.

Iran’s retaliation widened the war further: strikes on Israel, on American bases in Bahrain, Qatar and Cyprus, and on shipping through the Strait of Hormuz, a route carrying roughly a fifth of the world’s oil. The Houthis and Hezbollah re-engaged, and Gulf states hosting American forces found themselves exposed despite their recent thaw with Tehran. A Pakistan-mediated ceasefire took hold on 8 April 2026, though reports of continued strikes on relocated Iranian nuclear sites suggest an uneasy pause rather than a settled peace.

By the middle of 2026, Iran’s carefully built network of regional leverage lies in ruins by most measures: Hezbollah’s leadership decimated, Assad gone, air defences repeatedly breached, and now a Supreme Leader killed and replaced by a harder-line son. Notably, neither Russia nor China, Iran’s principal partners to the east, offered material military support during the fighting, suggesting that partnership is more an economic hedge than a binding alliance.

Whether this marks the definitive end of Iran’s regional project, or merely the latest and bloodiest turn in a far longer contest, is not a question this moment can honestly answer. The region’s recent history — premature victory claims after the Iraq war, the false dawn of the Arab uprisings, the presumed permanence of the 2015 nuclear deal — counsels against betting too heavily on finality. Iran’s system has absorbed severe shocks before. What is certain is that the balance of power in the Middle East looks nothing like it did even three years ago, and that any assessment of what comes next deserves more caution than confidence.
