Introduction: The End of the American Ordering Principle

The regional architecture of the Middle East was constructed on a foundational premise: that US primacy would function as the structural guarantor of stability among otherwise competing and fragile states. From the Carter Doctrine to the Gulf War coalition, from Operation Iraqi Freedom to the Abraham Accords, Washington served as the indispensable ordering authority—the external reference point against which Arab states calibrated their security postures, their economic partnerships, and their diplomatic alignments.

That premise no longer holds. The process of US retrenchment is neither accidental nor reversible. Across successive administrations—Obama’s strategic pivot to Asia, the first and second Trump terms’ transactional bilateralism, Biden’s selective re-engagement—the United States has progressively reduced its appetite for absorbing the costs of regional order maintenance. What has replaced US primacy is not a new hegemon but a structural vacancy, and into that vacancy three non-Arab regional powers have inserted their competing projects.

Mainly Iran and Israel, and currently much less soTürkiye, are not merely influential actors in the Middle East; they are advancing qualitatively distinct visions of regional order—or, more precisely, qualitatively distinct strategies for exploiting regional disorder. They are doing so in an Arab state system that, for reasons rooted deeply in history, institutional design, and the structural legacies of colonialism, is incapable of mounting a coherent collective response.

The article proceeds in seven substantive sections. It begins with a historical account of Arab identity formation, the rise and collapse of pan-Arabism (Arab nationalism), and the structural lessons of that trajectory. It then develops the theoretical framework—the penetrated regionalism model—before examining the receding US ordering role, mapping the tripartite non-Arab competition, and analysing Arab fragmentation as a structural enabler of external penetration. The article then turns to the global political economy stakes before concluding with a normative architecture for structured Arab multilateralism.

I. From Ottoman Dissolution to Post-Arab Spring Fragmentation

Colonial Cartography and the Paradox of Statehood

Arab political identity did not emerge from the boardrooms of European imperial powers but from the intellectual ferment of the Arab Nahda—the nineteenth-century renaissance of Arabic-language thought that generated a distinctly Arab political consciousness across Cairo, Beirut, Damascus, and Baghdad. The 1916 Arab Revolt translated this cultural solidarity into an attempted political project, only to collide immediately with the Sykes-Picot Agreement, the foundational betrayal that placed Arab political aspiration and European imperial cartography in permanent structural tension.

The Rise and Fall of Pan-Arabism

The Arab League’s founding in 1945 was the first institutional expression of Arab collective identity—but its organising logic, sovereign equality rather than federal union, simultaneously enabled collective action and constrained it. The 1948 Arab-Israeli War and the Palestinian Nakba (catastrophe) discredited existing Arab ruling elites and created the conditions for a new generation of revolutionary nationalist politics.

Gamal Abdel Nasser’s Egypt—culminating in the 1956 Suez Crisis and the United Arab Republic (UAR)—represented pan-Arabism’s maximum ambition. The UAR’s collapse in 1961 was the first major institutional demonstration that Arab unity was easier to aspire to than to institutionalise [1].[1] Kerr, M. H. (1971). The Arab Cold War: Gamal ‘Abd al-Nasir and His Rivals, 1958–1970 (3rd ed.). Oxford University Press. The Ba’ath Party’s competing vision, dominant in Syria and Iraq, transformed pan-Arab ideology from a popular movement into a legitimating vocabulary for single-party authoritarian rule.

The June 1967 War against Israel delivered the decisive blow. The swift military defeat was not merely a military loss but a civilisational shock—the Naksa (setback)—that discredited secular pan-Arab nationalism and accelerated a turn toward Islamist politics. The 1973 oil embargo transferred material power from the populous republican nationalist states to the conservative Gulf monarchies, shifting Arab political gravity decisively. Egypt’s Camp David Accords in 1979 formalised the outcome: the most powerful Arab state had permanently opted out of the pan-Arab confrontational posture toward Israel.

The Arab Spring and Definitive Fragmentation

The 2010–2011 uprisings briefly appeared as a pan-Arab moment—simultaneous popular mobilisations reflecting shared social grievances across a dozen states. They were not. Pan-Arab solidarity expressed itself at the level of shared sentiment; it was absent as political framework, institutional architecture, or coordinated strategy. The divergent trajectories of the uprisings—Tunisia’s democratic reversal, Egypt’s military restoration, Libya’s civil war, Yemen’s catastrophic conflict, Syria’s decade-long destruction—were not accidents. They were structural outcomes of an Arab state system that lacked collective governance capacity.

The Syrian war became the culminating expression of Arab political fragmentation: a multi-party proxy conflict involving Iran, Türkiye, Russia, Israel, the US, and multiple Arab states, with no collective Arab framework capable of shaping its outcome. The 2017 Gulf crisis—the Saudi-UAE-led blockade of Qatar—and the 2025 Saudi-UAE rift revealed that even within the Gulf Cooperation Council (GCC), underlying divergences were sufficient to produce open political rupture within the region’s most institutionally developed sub-framework.

The structural lesson of this arc is precise: pan-Arabism’s collapse is not the end of Arab identity but the end of a historically contingent political project that attempted to translate cultural solidarity into unified foreign policy. The absence of institutional architecture capable of managing internal differences—not the absence of Arab solidarity—is what failed. And that structural diagnosis points directly toward the institutional remedy.

II. Theoretical Framework: The Penetrated Regionalism Model

This article’s central theoretical intervention is straightforward: Arab strategic fragmentation is not a residual condition of failed state-building but a structurally reproduced outcome of asymmetric external penetration operating in the absence of a coherent regional counterweight. Three dominant theoretical accounts—realist balancing, constructivist identity, and liberal institutionalism—each capture part of the picture while missing its structure.

Realist accounts predict coalition formation against concentrated external threats, yet Arab states have systematically under-balanced against the tripartite non-Arab rivalry. Constructivist accounts overestimate normative solidarity as a political resource. Liberal institutionalist accounts underestimate how existing institutions have been hollowed out by the very fragmentation dynamics they were designed to manage.

Buzan and Wæver’s RSCT provides the foundational framework: regional security dynamics driven by patterns of amity and enmity among geographically proximate states [2].[2] Buzan, B., & Wæver, O. (2003). Regions and Powers: The Structure of International Security. Cambridge University Press. The Arab Middle East constitutes a fractured security complex—unlike a classical regional security complex (RSC) with a dominant internal ordering pole, the Arab sub-complex lacks a single organising centre and is simultaneously penetrated by three non-Arab regional powers. This article extends RSCT through the concept of differential penetration—the condition in which external powers exploit not merely the absence of regional order, but the specific fault lines within the penetrated complex.

Walt’s balance-of-threat theory refines the picture: proximity, offensive capability, and perceived aggressive intent operate differently across Arab states, producing the divergent Saudi-UAE deterrence orientation versus the Qatari-Omani diplomacy orientation [3].[3] Walt, S. M. (1987). The Origins of Alliances. Cornell University Press. Individual Arab states perceive the three external powers asymmetrically, preventing the formation of a unified threat perception. Bilateral security relationships with external guarantors substitute for collective Arab balancing—what this article terms alignment substitution.

The article’s distinctive contribution is an additional dimension: Arab fragmentation constitutes not merely a regional governance deficit but a source of systemic risk to the global political economy. Drawing on interdependence theory, the Arab world’s structural position as energy provider, host of maritime chokepoints, and node in global investment flows repositions the argument for Arab multilateralism from regional aspiration to systemic necessity.

The penetrated regionalism model synthesises these elements: (i) a regional sub-complex lacks a dominant internal ordering pole; (ii) multiple external powers exploit internal fault lines through differential penetration; (iii) individual member states substitute bilateral external alignment for collective balancing; (iv) the resulting fragmentation produces systemic risk effects extending into the global political economy. The model’s prediction is stark: fragmentation will intensify as US ordering capacity recedes unless a qualitatively different Arab collective institution emerges.

III. The Receding American Ordering Role

The arc of US retrenchment from the Middle East spans a generation. The Obama administration’s pivot toward Asia, its strategic hesitation over Syria, and the Iran nuclear negotiations signalled a recalibration of US regional priorities. The first Trump administration’s transactional bilateralism—maximalist pressure on Iran, the Abraham Accords, but strategic indifference to Arab state security concerns—introduced further uncertainty. The Biden administration’s selective re-engagement could not reverse structural trends. The second Trump administration has continued a pattern of selective presence combined with reduced appetite for the costs of regional order maintenance.

The critical distinction is between military presence and structural influence. US forces remain deployed across the region, yet their presence no longer functions as a structural guarantor of regional order. The 2019 Aramco strikes—in which Iranian-aligned forces struck the heart of Saudi oil infrastructure with limited US response—demonstrated in real time that extended deterrence had become contingent rather than credible. The 2026 Iran-Israel war, with its cascading effects on the Strait of Hormuz and Gulf energy markets, underscored the same point at a greater scale.

Arab states have responded to US retrenchment through hedging and alignment diversification—engaging China, Russia, and Türkiye as partial counterweights while maintaining core security relationships with Washington. This response is individually rational but collectively self-defeating. Greater freedom of manoeuvre for individual Arab states has not produced greater collective Arab leverage; it has produced a competitive fragmentation of diplomatic and economic assets that external powers exploit with precision.

IV. Three Non-Arab Powers, Three Projects

Iran: Network Power and the Axis of Resistance

Iran’s regional strategy is distinctive in kind, not merely in degree. The Islamic Revolutionary Guard Corps—Quds Force (IRGC-QF) model does not pursue hegemony through conventional military projection; it pursues permanent indispensability—ensuring that no regional settlement of consequence is possible without Tehran’s participation. The instrument is a network of ideologically aligned non-state actors: Hezbollah in Lebanon, the Iran-backed groups within the Popular Mobilisation Forces (PMF) in Iraq, the toppled Assad government in Syria, and, to a much lesser extent, the Houthis in Yemen and Palestinian Islamic Jihad in Gaza.

Israel: Security Architecture and the Normalisation Frontier

Israel: Security Architecture and the Normalisation Frontier
Israel’s regional strategy has undergone a structural transformation in the post-Oslo era. The Abraham Accords—normalisation agreements with the UAE, Bahrain, Sudan, and Morocco—represent not merely diplomatic achievements but a reordering of the Arab-Israeli strategic relationship: the construction of a security architecture bypassing Arab publics to build state-level partnerships around shared threat perception, principally toward Iran.

Israel’s preemptive military posture operates across multiple simultaneous theatres—Lebanon, Syria, Gaza, and the 2026 Iran campaign. The strategic logic of normalisation from above is complementary to this posture: embedding Israel as an indispensable security partner within the Arab state system while retaining unilateral freedom of military action when deemed necessary.

Türkiye: Neo-Ottoman Reach and the Soft-Hard Power Combination

Türkiye’s regional repositioning combines a growing military footprint—northern Syria, Libya, Somalia, and the Qatar base—with sophisticated soft power instruments: the Directorate of Religious Affairs (Diyanet), educational networks, humanitarian diplomacy, and increasingly, drone technology exports that have reshaped military balances in multiple conflict theatres. Türkiye presents itself as a legitimate co-architect of regional order, benefitting from its North Atlantic Treaty Organisation (NATO) membership while maintaining strategic ambiguity toward both Russia and Iran.

Türkiye’s ambition is structurally distinct from Iran’s or Israel’s: it does not seek permanent indispensability through proxy networks, nor security architecture through normalisation. It seeks recognition as an indispensable regional power in its own right—a Muslim-majority NATO member capable of bridging Western and Islamic political worlds while projecting autonomous strategic influence.

Interaction Effects: Where the Three Projects Collide

The three projects do not operate in parallel isolation. Syria has become the most acute theatre of tripartite overlap, with Iranian, Israeli, and Turkish military presences simultaneously operating—and occasionally colliding—across a single state’s territory. The Palestine question functions as a fault line that differentiates Iranian and Turkish postures from the Israeli-normalisation agenda. Points of inadvertent convergence also exist: competition among the three external powers can paradoxically stabilise certain local dynamics while destabilising others, as each power has structural incentives to prevent total collapse in areas of its investment.

V. Arab Fragmentation as Structural Enabler

Arab fragmentation is not simply the context within which external penetration occurs—it is the structural condition that external powers actively exploit and perpetuate. Three mechanisms are central.

Second, external powers exploit intra-Arab religious, sectarian, and identity cleavages with precision. Iran’s instrumentalisation of Shia political networks across Iraq, Lebanon, and Bahrain has been the most visible example—but it is not unique [7].[7] Gause, F. G. (2010). The International Relations of the Persian Gulf. Cambridge University Press. Türkiye’s deployment of Sunni solidarity narratives and the selective use of Palestinian solidarity as a legitimating frame by multiple external actors reflects a broader pattern of identity weaponisation against which Arab collective frameworks have no adequate response.

Third, and most consequentially, bilateral hedging strategies by individual Arab states accelerate rather than arrest collective strategic incoherence. When a Gulf state deepens its security relationship with Washington, tightens its economic links with Beijing, and simultaneously pursues diplomatic accommodation with Tehran, it is individually rational—but collectively, the multiplication of these strategies across a dozen Arab states produces a competitive fragmentation of diplomatic and economic assets that external powers read, correctly, as an open invitation for differential engagement.

VI. The Global Stakes: Arab Fragmentation as Systemic Economic Risk

The Arab World’s Structural Position in the Global Economy

The Arab world’s structural position in the global economy is not peripheral. Arab states account for approximately 30% of global oil production and hold over 55% of proven global oil reserves; Gulf liquefied natural gas (LNG) represents a critical and non-substitutable component of European, Asian, and South Asian energy security [8].[8] Cammett, M., Diwan, I., Richards, A., & Waterbury, J. (2015). A Political Economy of the Middle East (4th ed.). Westview Press. Three maritime chokepoints—the Strait of Hormuz, the Bab el-Mandeb, and the Suez Canal—collectively handle an estimated 30% of global seaborne trade. Their security is structurally inseparable from Arab political coherence.

The Economic Cost of Fragmentation

The economic costs of Arab fragmentation are concrete and quantifiable. Fragmented Arab SWFs frequently compete against one another in the same global asset classes, depressing returns and reducing collective negotiating leverage. Intra-Arab trade represents less than 10% of total Arab external trade—one of the lowest regional trade integration figures globally. Arab states collectively spend among the highest proportions of gross domestic product (GDP) on defence globally, yet without coordinated procurement, joint capability development, or interoperable command structures, this expenditure generates less collective security than its scale implies.

The 2026 Iran-Israel War as Economic Stress Test

The 2026 Iran-Israel conflict provided a real-time demonstration of the economic fragility that Arab political fragmentation produces. The effective partial closure of the Strait of Hormuz disrupted approximately 20% of global oil and LNG supply—cascading effects that extended from European spot markets to South Asian energy security arrangements. The absence of a coordinated Arab economic response meant individual SWFs managed conflict-driven market volatility in isolation.

The investor confidence deficit generated by the conflict—the demonstration that Arab states could be individually targeted without triggering collective Arab response—reinforced the perception that Arab economic assets remain individually exposed. The reconstruction challenge underscored the case for a collective Arab economic resilience framework capable of distributing recovery costs and coordinating post-conflict reconstruction financing.

VII. Toward Structured Arab Multilateralism

Why Existing Frameworks Fall Short

The GCC has achieved partial success—monetary coordination, common market elements, and defence cooperation among six Gulf states—but is geographically and politically insufficient as a broader Arab collective action framework. The Arab League has been hollowed out by competing member state interests and lacks the enforcement mechanisms to function as a genuine collective security or economic institution. Bilateral partnerships with external powers—however valuable—cannot substitute for the collective leverage and systemic risk reduction that only a multilateral Arab framework can generate.

Five Pillars of Structured Arab Multilateralism

The architecture this article proposes is not pan-Arabism revived. It does not aspire to unity of political system or foreign policy. It aspires to structured coordination—binding mechanisms on specific high-stakes domains that do not require resolution of all bilateral disputes as a precondition for collective action.

The first pillar is shared red lines against external interference: a binding collective commitment that any attempt by a non-Arab regional power to instrumentalise domestic Arab political, sectarian, or governance divisions triggers a coordinated Arab diplomatic and economic response. The second is crisis coordination mechanisms: binding consultation protocols automatically activated by external military action, economic coercion, or maritime disruption affecting any Arab state. The third is a unified economic posture: a coordinated framework governing Arab engagement with global investors, energy partners, technology firms, and multilateral institutions—enabling Arab states to negotiate as a bloc. The fourth is diplomatic burden-sharing: a structured division of labour between deterrence-oriented and diplomacy-oriented Arab states that transforms competitive fragmentation into a complementary architecture. The fifth is collective economic resilience infrastructure: a pan-Arab framework for coordinating energy grid interconnection, digital connectivity, food security reserves, and post-conflict reconstruction financing.

The Sovereignty Paradox and Comparative Lessons

The sovereignty paradox is the article’s most counterintuitive claim: binding multilateralism enhances rather than diminishes effective autonomy. Smaller Arab states that currently trade sovereignty for bilateral security guarantees from external powers would gain greater collective leverage through a multilateral framework. The institutional design challenge is managing internal heterogeneity—accommodating the diversity of Arab political systems, economic models, and foreign policy orientations without requiring prior harmonisation as a condition of participation [9].[9] Keohane, R. O., & Nye, J. S. (1977). Power and Interdependence: World Politics in Transition. Little, Brown.

Conclusion: Collective Architecture as Strategic Necessity

The argument of this article may be summarised in three propositions. First, Arab strategic fragmentation is not an Arab cultural condition but a structurally reproduced outcome of specific historical choices, institutional designs, and the colonial cartography of Arab statehood—and is therefore reversible. Second, the tripartite non-Arab competition among Iran, Israel, and Türkiye will intensify regardless of US strategic posture: retrenchment and re-engagement alike fail to substitute for Arab collective capacity. Third, Arab multilateralism is not a regional aspiration; it is a global systemic requirement—the absence of a coherent Arab interlocutor generates economic and security risks that extend well beyond the region’s borders.

From the Nahda to the Arab Revolt, from the Arab League to the UAR, from the Naksa to the Arab Spring, the Arab world has confronted a continuous structural dynamic: the recurring gap between the aspiration for collective action and the institutional architecture capable of sustaining it. The penetrated regionalism of the current moment is not a novel condition but the latest iteration of that dynamic—and the most consequential, because the stakes are now embedded in the global political economy in ways they were not during earlier iterations.

The historical arc teaches a precise lesson: the failure of maximalist pan-Arabism as a political project does not foreclose a minimalist but binding Arab multilateral framework—one that does not aspire to unity but to structured coordination, does not suppress state sovereignty but pools it selectively. The question is whether Arab political leaderships are prepared to recognise that the bilateral hedging strategies that have served individual state interests in the short term are, in aggregate, the mechanism by which their collective strategic position continues to erode.

The Arab world’s most consequential strategic choice in the coming decade is not which external power to partner with, but whether to present itself as an actor with collective agency or a terrain on which others’ projects are contested. The architecture for the former exists; what remains is the political will to build it.
