On deterrence and escalation: Decoding the Gulf crisis in a fragmented regional order

The possibility of further escalation can result in the Strait of Hormuz emerging as the central chokepoint where strategic signalling, financial distress, and military escalation can become hazardous for the Gulf region

The Gulf is facing a multifaceted crisis in which a direct United States-Israel-Iran confrontation could significantly destabilise regional security, disrupt global energy markets, and intensify existing geopolitical rivalries across the broader Middle Eastern region.

Over the past few days, there has been a sharp escalation in tensions after the American and Israeli strikes on Iran, followed by Iranian retaliation and wider spillover risks across Gulf maritime routes and bases. The possibility of further escalation can result in the Strait of Hormuz emerging as the central chokepoint where strategic signalling, financial and commercial distress, and military escalation can become hazardous for the Gulf region.

The Gulf has long absorbed pressure through proxies and deniable attacks. However, the current scenario is defined by visible military actions and explicit attribution, which curtails decision making and increases the likelihood of strategic miscalculation. 

Iran’s role in this crisis is best understood through a combination of challenges like deterrence posture, domestic legitimacy pressures, and controlling the escalation. Tehran has historically relied on a spectrum of tools to deter adversaries and heighten the strategic costs of coercion.

The present crisis appears to be testing how much leverage Iran can generate without triggering overwhelming retaliation—while also meeting internal expectations of response. The Iranian retaliation has been substantial in volume but uneven in effect, and this pattern is consistent with a strategy that seeks to demonstrate capability and resolve while avoiding actions that would unify outside powers into an open-ended campaign against Iran. 

In the case of Israel, its role is shaped by Iran’s regional manoeuvres and its desire to restore deterrence. Israeli strategy often aims to degrade capabilities and signal that escalation will not be without adverse consequences. Yet, Israel also faces the classic constraint that military success does not necessarily translate into durable political outcomes, especially if strikes catalyse wider regional mobilisation. The present crisis environment increases Israel’s exposure to retaliation and raises the risk that conflict theatres connect.  

The United States' involvement in this crisis has overlapping priorities that are not always perfectly aligned.

It majorly involves defending allies and partners, preventing regional escalation, maintaining freedom of navigation, and reducing economic shock, while also managing alliance credibility. From an operational perspective, American bases and naval assets across the Gulf region create both reassurance for partners and obvious targets for coercive actions, increasing the probability that even “limited” exchanges can have a spillover effect.  

For the Gulf states, the crisis is acutely uncomfortable, because it concentrates risk on their territory while limiting actions to avoid escalation. Many Gulf states are hosts to American assets or military bases. These Gulf states also maintain varying degrees of diplomatic engagement with Iran, as well as—in some cases—calibrated ties with Israel.

Iranian actions against American infrastructure and shipping lanes have led these Gulf states to face the dual vulnerability of both physical exposure (bases, ports, energy infrastructure) and economic risks (insurance costs, investor risk perception, and risks for logistics hubs). These apprehensions of a broader conflagration enhance the risk of retaliation.  

The economic aspect of this crisis in the Gulf region also cannot be ignored. Even partial physical damage can generate enormous financial impact.

For instance, a few tanker incidents can push freight rates up and inflate risk premiums while refineries and gas buyers scramble for alternative routes and mechanisms. This amplifies price volatility and creates political pressure far beyond the region. The shipping disruptions and oil price reactions reflect how quickly the Gulf region’s security environment transmits into global macroeconomic anxiety.

This is significant because commercial shipping patterns function as a strategic variable in their own right. Such disruptions can intensify tensions and contribute to escalation, particularly when economic pressure becomes a justification for retaliatory actions. The current situation can act as catalyst for the Gulf states in an already volatile scenario. 

A further complication is that this crisis is unfolding against a backdrop of multiple, partially connected conflicts.

The Israel-Hamas conflict and its regional reverberations, intermittent Red Sea insecurity, and long-standing Iran–Israel hostility create a scenario in which actions in one theatre can be interpreted as part of a unified campaign. This reflects broader patterns of regional instability and proxy-driven dynamics across ongoing conflicts.

The current escalation risks strengthening these linkages by transforming the Gulf region from a peripheral source of instability into a direct arena of confrontation.

The US-Israel strikes on Iran raise fundamental questions about the political order, deterrence equilibrium, and escalation dynamics that may emerge after the initial military phase. This uncertainty is especially pronounced in this region where security structures and economic stability are closely interconnected.

All in all, the Gulf crisis is not simply 'Iran versus Israel' or 'Iran versus the United States'. It is a compounded stress test of deterrence, alliance politics, and the global energy-shipping system operating through narrow geographic chokepoints and dense military basing patterns.

Iran seeks to deter without inviting decisive defeat; Israel seeks to reduce perceived existential threats and restore deterrence; the US seeks to protect forces, reassure allies and partners; and Gulf states seek to avoid becoming the theatre where strategic contests are settled.

The interaction of these competing interests, in an environment marked by deep mistrust and rapid escalation, shapes the current risk more than the intentions of any single actor.
