Could a US-Iran War Force Allies to Abandon Washington?

The geopolitical architecture of the Middle East, a complex tapestry woven with threads of historical enmity, religious divergence, and strategic competition, stands at an inflection point. For decades, the regional status quo has been defined by a precarious balance of power, underpinned by the heavy hand of American influence and the persistent, expansionist ambition of the Islamic Republic of Iran. Yet, as tensions between Washington and Tehran oscillate between cold hostility and the brink of kinetic conflict, the global community finds itself contemplating a chilling prospect: a sudden, large-scale war. Should such a conflict erupt, the shockwaves would not be confined to the combatants; they would ripple outward, testing the structural integrity of alliances that have stood for half a century and forcing regional actors to engage in a desperate, high-stakes recalculation of their survival strategies.

The prospect of an all-out war between the United States and Iran is no longer merely a theoretical exercise in military posturing. The proliferation of proxy groups, the advancement of Iran’s nuclear program, and the hardening of American domestic policy regarding the Middle East have created a volatile environment where a single miscalculation—a downed drone, a targeted strike on an oil tanker, or a catastrophic cyberattack—could trigger a cascade of events leading to total war. In such a scenario, the established binary of “pro-American” and “pro-Iranian” camps would likely shatter, giving way to a more chaotic, multipolar landscape defined by pragmatism, survivalism, and opportunistic pivoting.

At the heart of this shifting paradigm are the Gulf Cooperation Council (GCC) states. Countries like Saudi Arabia, the United Arab Emirates (UAE), and Qatar have long relied on the United States as their primary security guarantor. However, the last decade has seen a notable erosion of absolute confidence in the “American umbrella.” From the perception of a US “pivot to Asia” to the inconsistent responses to attacks on regional energy infrastructure, these nations have begun to hedge their bets. If a war were to break out tomorrow, the immediate question would be which ally is the most likely to break ranks, and in what direction would they pivot?

To understand the potential for a realignment, one must look closely at the UAE. Long considered the most pragmatic of the Gulf monarchies, Abu Dhabi has, in recent years, demonstrated a willingness to engage in direct diplomacy with Tehran to de-escalate tensions. Following the 2019 attacks on tankers off the coast of Fujairah, the UAE began a discreet but deliberate process of recalibrating its relationship with Iran. This was not a betrayal of the United States, but a realization that in an era of waning American interventionism, geographic proximity to Iran requires a modicum of diplomatic insurance. If Washington were to launch a campaign against Iranian military infrastructure, the UAE would be acutely aware that it sits in the proverbial firing line. The potential for retaliatory strikes from the Islamic Revolutionary Guard Corps (IRGC) or its regional proxies could paralyze the UAE’s economy in a matter of hours.

This brings into focus the existence of “secret negotiations.” While international headlines remain focused on the bluster of public statements, the real work of regional diplomacy is often conducted in the hushed corridors of Muscat, Baghdad, and increasingly, via backchannel communications involving private equity envoys and high-level intelligence officers. There is mounting evidence to suggest that several key US allies are currently engaged in preemptive, clandestine talks with Iranian counterparts. The goal of these discussions is not necessarily to form a new military alliance with Tehran, but to secure “neutrality pledges” or non-aggression pacts that would survive the outbreak of a US-Iran war.

The complexity of these secret negotiations cannot be overstated. Consider the case of Qatar, which maintains a delicate balancing act as the host of Al Udeid Air Base—the largest American military installation in the Middle East—while simultaneously acting as a primary diplomatic intermediary for Iran. In the event of war, Qatar would find itself in a position of existential strain. Would it allow the United States to launch strikes from its soil, thereby making it a target for Iranian ballistic missiles? Or would it impose restrictions on the US military, effectively breaking ranks and forcing a confrontation with Washington? The maneuvering room for Doha is razor-thin, and it is likely that Qatari officials are currently exploring every available diplomatic avenue to ensure that they are not forced to choose sides in a binary conflict that threatens their sovereign existence.

The geopolitical domino effect of a US-Iran war would also extend to Iraq, a country that currently acts as the primary arena for US-Iran rivalry. The Iraqi government, trapped between its dependence on US financial systems and the pervasive influence of Iran-backed militias within its state institutions, would effectively cease to function as a cohesive sovereign entity. If war were declared, the Iraqi state would be torn apart as various factions choose to either support the American effort, remain neutral, or join the Iranian counter-offensive. This disintegration would force neighboring countries like Jordan and Turkey to fundamentally rethink their border security and regional postures.

Turkey, a NATO member that often acts as an outlier in Western policy, represents another critical variable. Ankara has frequently positioned itself as a bridge between the West and the Middle East. However, Turkey’s own strategic interests—particularly regarding Kurdish autonomy and the reconstruction of Syria—often align with Iran’s containment policy, even while it competes with Tehran for regional influence. In a conflict scenario, Turkey might initially offer rhetorical support to the United States but would almost certainly refuse to engage militarily, prioritizing the containment of refugee flows and the protection of its own energy transit routes over the dictates of its NATO commitments. This “soft break” from the American line would constitute a massive disruption to the existing trans-Atlantic consensus.

The role of Israel in this calculus adds a layer of extreme complexity. While Israel is undoubtedly the United States’ most committed partner in containing Iran, an all-out war would test the limits of their coordination. Israel would likely demand to be a part of the conflict, viewing the destruction of Iranian nuclear facilities as a strategic necessity. However, the US may prefer a more limited engagement to prevent the conflict from spiraling into a regional apocalypse. If Washington chooses to restrain Israel, a profound rift could emerge between the two traditional allies, forcing other regional players to decide whether they follow the American path of limited engagement or the Israeli path of total, decisive destruction.

Furthermore, we must address the role of external powers, specifically China and Russia. Over the past several years, China has emerged as a significant economic lifeline for Iran, particularly through the purchase of Iranian crude oil. In a war scenario, Beijing would face a direct challenge to its energy security. While China is unlikely to intervene militarily on behalf of Iran, it could provide critical intelligence, cyber support, or economic shielding that would frustrate American war objectives. This would force US allies in the Gulf to confront a terrifying reality: the world is no longer a unipolar space where the United States can dictate the outcome of every conflict. If an ally perceives that the United States cannot guarantee victory against an Iranian-Chinese-Russian axis, they will inevitably drift toward a position of strategic autonomy.

The secret negotiations mentioned earlier are likely centered on the issue of energy and maritime security. The Strait of Hormuz, through which a significant portion of the world’s oil supply passes, would be the first point of failure in a US-Iran war. Iran has repeatedly threatened to close the strait, a move that would send global energy prices skyrocketing and plunge the global economy into a recession. Allied states, realizing that the US Navy might not be able to immediately secure the waterway against swarm attacks and sea mines, are likely attempting to reach an accommodation with Tehran regarding the safety of their tankers. Such an arrangement would constitute a functional exit from the American-led maritime security coalitions, representing a silent but seismic shift in regional power dynamics.

To appreciate the gravity of these potential shifts, one must look at the historical precedent of the Iran-Iraq War in the 1980s. During that conflict, the regional states largely coalesced around a stance of containment. But the modern context is vastly different. The rise of sophisticated drone technology, the maturation of Iran’s “Axis of Resistance” (spanning from Yemen’s Houthis to Lebanon’s Hezbollah), and the weakening of American domestic appetite for foreign intervention have created a landscape where the costs of war are no longer confined to the battlefield. Today’s allies are more fragile, their domestic populaces less tolerant of instability, and their economies more deeply integrated with global markets that would be devastated by a prolonged conflict.

The internal political pressures within these allied nations should not be underestimated. In many Gulf states, there is a growing disconnect between the elite’s strategic reliance on the US and the public’s growing skepticism of foreign-induced regional instability. Should a war begin, the governments of these nations would have to manage significant domestic unrest. A strategy of neutrality or quiet engagement with Tehran might be the only way for these regimes to maintain their own domestic legitimacy. For an autocrat, the survival of the throne is far more important than the strategic goals of an overseas superpower.

Consequently, the “crucial detail” that often goes overlooked in mainstream reporting is the evolution of the “non-aligned” bloc within the Middle East. If a US-Iran war were to occur, we would likely see the formation of a temporary, emergency coalition of states—perhaps led by Oman and Qatar—attempting to mediate a cease-fire from day one. This coalition would not be acting out of sympathy for the Iranian regime, but out of a desperate need to survive. They would likely leverage their connections with both Washington and Tehran to create a “buffer zone” or a “safety corridor” that would exclude them from the worst of the conflict.

The United States, for its part, would find it increasingly difficult to demand total compliance from its partners. Washington’s leverage has historically rested on the promise of security. If that security is compromised by the very conflict the US initiates, the transactional nature of the US-Gulf relationship will be laid bare. We would see a new form of “multi-alignment,” where countries like the UAE, Saudi Arabia, and even Jordan maintain multiple, sometimes contradictory, security relationships. This is not necessarily the end of the US presence in the Middle East, but it is the end of the US-led order as we have known it since the end of the Cold War.

Analysis of the intelligence environment suggests that there is already a profound lack of trust regarding the “endgame” of a US-Iran war. Many regional capitals fear that the United States would initiate a conflict, inflict significant damage on Iran, and then withdraw, leaving the regional states to deal with a wounded, vengeful, and emboldened Iranian regime. This “hit-and-run” fear is the primary driver of the secret negotiations. The allies do not want to be the ones left behind to clean up the wreckage. They are demanding guarantees that do not exist, and in the absence of those guarantees, they are making their own contingency plans.

As we look toward the horizon, the likelihood of a sudden conflict remains high. The geopolitical climate is brittle, the communication channels between Washington and Tehran are dangerously thin, and the regional actors are clearly preparing for a scenario where they are forced to break with their traditional protector. The breaking of ranks may not happen through a dramatic public announcement or a formal renunciation of treaties. Instead, it will likely happen through a series of quiet, incremental choices: a missed intelligence-sharing meeting, a closed-door discussion between a Gulf intelligence chief and an Iranian counterpart, or a public refusal to allow the use of air bases for strike operations.

This shift would signify the definitive conclusion of the post-WWII era of American hegemony in the Middle East. It would usher in a period of “regionalism,” where the local powers, freed from the strictures of the US-Soviet or US-Iran binary, look to define their own survival based on geographic and economic necessity. While the United States would remain a significant military power, its ability to command the actions of its regional partners would be fundamentally diminished. The world would see a more fragmented, more complex, and more dangerous Middle East, where the rules of engagement are determined by the immediate needs of the sovereign states involved rather than the grand strategies of external superpowers.

The potential for such a reconfiguration poses a massive challenge for Western policymakers. If the United States continues to treat its regional allies as subordinates rather than sovereign partners with their own existential imperatives, it risks being surprised by their actions in the heat of a conflict. The current reliance on the assumption of unwavering loyalty is a dangerous gamble that ignores the realities of the changing global order. A smarter approach would be for the United States to actively engage in transparent, multi-level diplomacy with its partners about the dangers of a potential war, rather than operating on the assumption that they will follow the American lead blindly.

Ultimately, the stability of the Middle East hinges on the ability to prevent a war that no one—not even the regional actors—truly wants. However, if the trajectory of current events is not altered, the necessity of survival will dictate the loyalties of the players involved. When the drums of war beat loudest, the true character of alliances is revealed. For the United States, the lesson may be that in the modern Middle East, a partner’s loyalty is only as strong as the security that the partnership provides. When that security fails, or when the cost of maintaining it becomes too high, even the most enduring alliances are destined to fray, break, and be replaced by the cold logic of self-interest.
