The Middle East is undergoing its most profound strategic transformation since the end of the Cold War. On 28 February 2026, the United States and Israel launched a coordinated strike against Iran, killing its Supreme Leader, Ayatollah Ali Khamenei, and targeting key military and nuclear facilities. On 7 and 8 July, U.S. Central Command (CENTCOM) struck more than 100 Iranian military targets along Iran’s southern coastline, prompting Iran to retaliate with missiles and drones against U.S. military installations in Kuwait and Bahrain, while Yemen’s Houthis separately announced a renewed blockade of the Red Sea. Together, these developments placed two of the world’s most important maritime trade routes under renewed pressure. More importantly, they show that the post-Cold War regional order is ending and that a more contested, increasingly multipolar balance of power is emerging, with consequences that will extend well beyond the Middle East.
For three decades, the region’s stability rested on a simple assumption: American strategic primacy, Israeli military superiority, and regional acquiescence. That assumption no longer describes reality. The Middle East is moving toward a more contested and multipolar strategic environment, and policymakers who still rely on the old compass will be surprised by the region they are trying to manage. Rather than returning to the familiar security architecture of the post-Cold War era, influence is now increasingly shared among state and non-state actors alike.
Consider what actually happened. Iran absorbed the heaviest blow any state has suffered in the region in a generation—its Supreme Leader dead, its nuclear and military infrastructure struck directly—yet it did not collapse. It closed the Strait of Hormuz almost entirely for weeks, at one point reducing maritime traffic by more than 90 per cent, according to the International Energy Agency, and has continued to demonstrate its ability to disrupt commercial shipping months later. Strategically, resilience proved as important as military capability. Expectations that an overwhelming force would fundamentally alter Iran’s regional position have, so far, not been borne out.
Meanwhile, the Gulf states, which spent the war trying to remain neutral while hosting American military bases, have drawn their own conclusions. Trade between the Gulf Cooperation Council and China has climbed to roughly $300 billion annually, while Gulf investment increasingly flows into Chinese green energy, ports and advanced technology. This does not represent a strategic shift away from Washington. American arms sales still far exceed China’s, and no Gulf government expects Beijing to replace the United States as its primary security guarantor. Rather, it reflects a deliberate hedging strategy—one adopted by states that no longer regard reliance on a single external power as sufficient. Moscow, for its part, deepened cooperation with Tehran through intelligence sharing and defence collaboration, reinforcing the perception that the regional balance is becoming progressively more complex.
Add to this the Red Sea, where Houthi attacks have continued almost uninterrupted since late 2023 and are now estimated to cost the global shipping industry between $15 billion and $20 billion annually in rerouting expenses and insurance premiums alone. Together with the Strait of Hormuz, these waterways have become strategically contested maritime corridors whose security now carries global economic consequences. In this way, the Middle East’s geography has become one of its most consequential geopolitical assets.
None of this means American or Israeli power has become irrelevant—far from it. Only Washington and Tel Aviv possessed the military capabilities to execute the February strikes, and that reality continues to shape regional calculations. Yet conventional military superiority did not produce strategic closure. Instead, it produced a Strait whose security can no longer be taken for granted, Gulf partners that are diversifying their strategic relationships, and a regional order that has become more multipolar rather than less. Put differently, military superiority is not the same as strategic control. The events of recent months have illustrated the widening gap between the two.
What ties these developments together is a fundamental transformation in deterrence itself. For decades, deterrence was largely territorial—confined to borders, individual fronts and separate theatres of conflict. Today, it has become increasingly networked. A strike on Iran reverberates through Lebanon, Iraq, Yemen, the Gulf and the Red Sea because Tehran has spent decades building relationships capable of extending any confrontation beyond its immediate point of origin. As geopolitical analyst Pepe Escobar has argued, the region’s conflicts should no longer be understood as isolated crises but as interconnected theatres operating within a broader strategic framework. A region that deters in this way cannot be managed through doctrines developed for an earlier era of compartmentalised conflict.
The emerging Middle East is therefore not descending into disorder; it is evolving toward a different kind of order—one characterised by multiple centres of influence, distributed forms of power and increasingly pragmatic diplomacy. This is the new balance of power: regional actors are no longer merely reacting to decisions taken elsewhere. They are shaping events according to their own strategic priorities while balancing relationships with the United States, China, Russia and one another. The challenge for policymakers is not to recreate the strategic landscape of the past but to understand the one that is rapidly taking shape.
Recognising this new balance of power is not a concession to instability; it is the first step toward building a regional order capable of managing it.
