The Future of Middle East Security: Layered Security vs. External Umbrella

The concept of a “regional NATO” can only be achieved by abandoning the ambition of an “all-encompassing alliance” in favor of a gradual integration process, one that ends decades of unilateral reliance on external security umbrellas that can no longer be trusted.

The Middle East is undergoing a fundamental shift that is redefining the meaning of security as well as its actors and tools. Over the past three years, watershed moments from Israel’s war on Gaza to the renewed U.S.-Israeli conflict with Iran have revealed that outdated calculations and established frameworks can no longer guarantee regional stability and security.

As these transformations unfold, a debate has resurfaced over the need for a collective regional security framework, often referred to as a Middle Eastern or “Islamic NATO,” in response to waning confidence in the external security umbrella and its associated guarantees. While this concept of collective security is significant, it faces deep-seated structural obstacles, making it more likely to lead to strategic hedging than to the formation of a rigid military alliance.

The Middle East Strategic Alliance

The debate over a regional alliance is not new. The concept has been proposed repeatedly over the past two decades, in various forms—from an “Arab NATO” to a “Middle East strategic alliance.” What distinguishes the current moment is that the proposal is no longer merely theoretical; it has taken on urgency due to a succession of shocks on the ground that have affected multiple states simultaneously. Israel’s war on Gaza and the bombing of a residential complex in Doha deeply shook Arab Gulf capitals. The attack, on a state bound to the West by highly developed security alliances and hosting the region’s largest U.S. military base, revealed that an American presence no longer guarantees automatic immunity.

The war of February 2026 further deepened the shock, as Iranian drone and missile strikes claimed the lives of at least 28 people across the six Gulf Cooperation Council (GCC) states, transforming the threat from a theoretical possibility into a bloody reality affecting cities and vital infrastructure. The assumption that Western security guarantees would remain stable and valid has also eroded, especially in light of the structural and strategic crisis facing NATO, diverging U.S.-European priorities, and Washington’s increasing preoccupation with the Indo-Pacific and its rivalry with China.

The upshot is that two critical factors—the eroding credibility of external protection and the escalating direct threat—are together fueling a conviction that the region must become more self-reliant in its defense.

Balances and Deterrence in Wartime

To interpret the current landscape, one must revisit the theoretical frameworks used to understand state behavior during times of peril. Classical alliance theory, closely associated with the realist school of international relations, holds that states form alliances either to balance against a rising power or to align with a specific power. However, American political scientist Stephen Walt has refined this premise through his “balance of threat” theory, showing that states do not merely ally against a superior power to achieve a balance of power; rather, they form alliances in opposition to the power they perceive as a threat. This hinges on the interplay of four factors: aggregate capability, offensive capability, geographic proximity, and aggressive intentions. These factors are crucial: the primary obstacle to forming a broad coalition of states lies not in a lack of capabilities but in the level of threat perception. For instance, some nations may view Iran as an existential adversary, while others prefer to contain it through diplomacy, de-escalation, and economic cooperation.

Theoretical scholarship offers a second caveat, known as the “alliance dilemma,” a syndrome involving a choice between two risks: the risk of being dragged into an ally’s wars that do not serve one’s direct interests, and the risk of being abandoned when support is most needed. Viewed through this lens, the dilemma facing Gulf states is not merely about choosing a camp. It is about avoiding being swallowed up by an alignment designed elsewhere to serve priorities incompatible with their own, or being trapped in an alliance that undermines their sovereignty, drags them into a sphere of dependency, and entangles them in confrontations they did not choose.

A third theoretical pillar is the concept of deterrence as a strategy for crisis management. Here, it is important to distinguish between “direct deterrence”, exercised by a state to protect itself, and “extended deterrence,” provided by a major power to its allies.

For decades, the Gulf’s security architecture has rested on extended deterrence provided by the U.S. and the accompanying guarantees of protection. However, the effectiveness of this deterrence has hinged entirely on a single, fragile variable: credibility. When Gulf cities were bombed and the U.S. umbrella failed to deliver a decisive deterrent response, that credibility eroded and the value of the deterrence equation collapsed. This created strategic incentives to build homegrown deterrence to ensure autonomy and shifted aspirations toward the possibility of forming a regional alliance.

Three Competing Projects

The region today is clearly far from any optimistic scenario. It is not moving toward a single, unifying security pole but rather toward three competing alignment projects, with the Gulf states at their intersection. The first project is the Iranian network—an unconventional structure based on missile capabilities, drones, proxies, and the ability to threaten maritime corridors, rather than on formal alliances. It is a striking paradox that Iran itself has called for an “Islamic security alliance” comprising Pakistan, Saudi Arabia, Türkiye, Egypt, and Qatar—while excluding the U.S. and Israel. This proposal complicates the logic of a NATO-style alliance directed against Iran, because the proposed members include the very states seen as candidates for the opposing bloc.

The second project is the Israeli axis—or what Prime Minister Benjamin Netanyahu has termed the “Hexagon,” which extends from the Eastern Mediterranean to South Asia and seeks to integrate Israeli capabilities into a broader regional system. The third is a Gulf-Arab nucleus; this is the closest formulation to the proposal under discussion here and is grounded in shared self-interest and complementary capabilities. The challenge for the GCC states lies not in choosing between two opposing camps but in managing their positioning among these three projects in a way that preserves their decision-making autonomy and avoids the trap of dependency.

Factors of Success and Structural Obstacles

The countries that could launch a Gulf-Arab nucleus undeniably possess exceptional assets. The Gulf states represent a global economic and energy powerhouse, commanding vast financial resources and growing capabilities in technology and defense. Meanwhile, Egypt maintains the largest Arab military force and Jordan offers advanced security and intelligence expertise. Beyond this core grouping, the nucleus could draw on the distinct strengths of key non-Arab partners such as Türkiye’s sophisticated defense industry and Pakistan’s strategic depth by virtue of its military and nuclear capabilities. Yet these assets also run up against structural obstacles that cannot be ignored. Practical implementation of an existing Gulf joint defense agreement has remained limited for decades, raising legitimate questions about the feasibility of building a broader, potentially more complex, alliance.

However, the Mecca Agreement, signed on August 7, 2026, by Saudi Arabia, Türkiye, and Pakistan, formalized a trilateral collective-defense pact, setting a significant precedent. The agreement leverages the distinctive strengths of each signatory, bringing together Türkiye’s NATO-integrated capabilities and robust defense industrial base, Pakistan’s nuclear arsenal, and Saudi Arabia’s financial and diplomatic weight under a single umbrella, laying a foundation for broader regional security cooperation. Whether the Mecca Agreement evolves into the institutional core of an “Islamic NATO” or remains symbolically important but functionally limited will depend on how its member states respond when tested.

The most complex factor remains the Palestinian issue, which imposes a political ceiling on any alignment that includes Israel—particularly after Israel’s attack on Doha. In theoretical terms, the obstacles center on two key variables: differing threat perceptions and limited institutional credibility. These factors render any collective defense treaty modeled on Article 5 of the North Atlantic Treaty—which stipulates that “an armed attack against one or more [NATO members] in Europe or North America shall be considered an attack against them all”—unfeasible for the foreseeable future. At the same time, there are positive indicators, notably the unanimous Arab opposition to attacks on Gulf states and Jordan.

Selective Hedging

Looking ahead, the most realistic option for the region is selective hedging within a framework centered on the Gulf. This approach would not require states to align their foreign policies—an impossible condition given their divergent interests—but would instead seek a minimum level of consensus on shared “red lines”: protecting sovereignty, securing energy infrastructure, safeguarding maritime corridors, and shielding urban centers from attack.

This approach could be implemented through four progressive layers. The first would begin by deepening intra-Gulf integration, specifically in the realms of air and missile defense, information-sharing, and the protection of critical infrastructure, to serve as a cohesive, solid nucleus. The second layer would involve diversifying external partnerships, without sliding toward becoming a rigid bloc. This could be achieved through flexible partnerships with Türkiye, Pakistan, and the United Kingdom, as well as with NATO—through the Istanbul Cooperation Initiative—thereby distributing risk and avoiding reliance on a single guarantor. A third layer would entail constructing an Arab security perimeter around the Gulf, involving Jordan and Egypt, focused on coordinating air defense and intelligence, without this escalating into a binding, traditional military alliance. This framework would be completed by a fourth layer: maintaining open diplomatic channels with Iran to manage escalation and prevent a slide into all-out confrontation, particularly given that a prolonged U.S.-Iran truce, redrawing the rules of engagement, appears increasingly possible.

Recommendations

It is important to use the term “layered security architecture” rather than “Middle East NATO.” This avoids echoing NATO’s Article 5 model and sidesteps potential provocations associated with the “NATO” label and its symbolic baggage. Second, analysis of the issue should clearly distinguish among the three competing projects described above to avoid the misconception of a single, cohesive initiative.

Finally, it is vital to direct investment toward interoperable capabilities, including integrated air defense systems, early warning networks, and information-sharing protocols. The Mecca Agreement can serve as a strong foundation for such efforts. This approach can yield high returns in terms of deterrence, enabling genuine functional cohesion.

Conclusion

The concept of a “regional NATO” has moved beyond being merely an attention-grabbing headline, yet it is not—for now—a mature project ready for immediate implementation. It reflects a genuine need driven by major geopolitical shifts, but translating this need into an institutional reality will require setting aside the ambition of an “all-encompassing alliance” in favor of a gradual process of integration, rooted in shared capabilities and mutual trust.

If the states involved succeed in this endeavor, the Middle East could witness the emergence of a more independent and balanced regional order. This will not happen in one dramatic leap but through a calculated process of strategic, functional accumulation—one that ends decades of unilateral reliance on external security umbrellas that can no longer be guaranteed.
