KOTA KINABALU, Malaysia — In recent weeks, the conflict between the United States and Iran has come to resemble a swinging pendulum, vacillating between confrontation and restraint. Nowhere is this more evident than in the uneasy, almost theatrical contest over the Strait of Hormuz. Iran periodically signals that it has the capacity, and perhaps the willingness, to blockade the waterway, while the US responds with a posture of counterblockade and maritime assurance. Both sides appear to be probing each other’s red lines, yet are equally careful not to cross them outright.
The Strait of Hormuz has become a focal point not merely because of its narrow geography, but because it functions as a critical artery for global energy flows. For Iran, the notion of closing the strait has never been a purely military option; it is, more importantly, a tool of strategic deterrence. Tehran does not necessarily need to shut down the waterway indefinitely. It only needs markets to believe that such a closure is plausible. Once that perception takes hold, oil prices rise, insurance premiums surge, and global supply chains begin to tighten. In this sense, Iran is employing a classic form of asymmetric strategy: leveraging relatively low-cost actions or even signals to generate disproportionately high global impact.
Yet, therein lies the dilemma. A full closure of the Strait of Hormuz would not only constitute a direct challenge to the US, but would also inflict immediate economic harm on Europe, East Asia, and even countries that maintain relatively cordial relations with Iran. Energy prices would spike dramatically, shipping costs would escalate, and the likelihood of broader military intervention would increase. Tehran is acutely aware of these risks. Consequently, its approach tends to hover at the threshold of disruption rather than crossing into outright blockade. This includes tactics such as the harassment of commercial vessels, the implied or limited use of naval mines, and pressure exerted through regional proxies — actions designed to signal capability without triggering full-scale retaliation.
The American response reflects a different but equally calculated strategic logic. Washington’s objective is not solely to ensure the free flow of maritime traffic, but also to reinforce its role as a guarantor of global public goods, particularly in the domain of security. Naval patrols, convoy operations, and coalition-building efforts are not merely operational measures; they are political signals. They communicate that the US retains both the capacity and the willingness to safeguard critical nodes of the international order. This message resonates far beyond the Middle East. For many US allies, especially in Europe and Asia, the central concern is less about the immediate dynamics of the Gulf and more about the broader question of American reliability.
What is particularly striking is how this cycle of “blockade” and “counterblockade” has gradually evolved into a tacitly understood form of confrontation. Iran demonstrates its disruptive potential, but stops short of provoking a full-scale war. The US, in turn, asserts its presence and deterrence capabilities, but avoids becoming deeply entangled in another protracted conflict. Both sides seek to project strength to domestic audiences and international observers, while simultaneously maintaining a degree of stability in practice. At its core, this is not conflict resolution but conflict management — a calibrated equilibrium sustained through mutual caution.
Viewed from a broader geopolitical perspective, the implications of this dynamic may prove more enduring than those of a conventional war. One immediate effect is the renewed urgency surrounding energy diversification. Countries in Europe and Asia are once again confronted with the vulnerabilities associated with dependence on a single chokepoint. Strategic petroleum reserves, alternative supply routes, and investments in renewable energy are all being reconsidered with greater seriousness. At the same time, maritime security is undergoing a subtle but significant remilitarization. Naval presence, which in some regions had receded in prominence, is returning as a central instrument of both cooperation and competition among major powers.
Equally important is the precedent this situation sets for other regions. It demonstrates that even actors with comparatively limited capabilities can exert meaningful influence over great powers by targeting critical nodes in the global system and operating within the so-called gray zone — that ambiguous space between peace and open conflict. For middle powers and regional actors elsewhere, this serves as a reminder that strategic leverage does not always depend on conventional military parity. Control, or even the credible threat of disruption, over key transit points can reshape the calculations of far stronger adversaries.
However, a prolonged state of calibrated tension is not without its risks. The margin for error in such scenarios is often perilously thin. A misidentified target, an errant missile, or the sinking of a commercial vessel could rapidly escalate into a broader confrontation. Under current conditions — where domestic political pressures are mounting in many countries — leaders may find themselves with limited room to de-escalate once a crisis spirals. The very mechanisms designed to maintain deterrence could, under strain, become catalysts for unintended conflict.
In this light, the current pattern of intermittent clashes and pauses should not be mistaken for genuine de-escalation. Rather, it represents a carefully maintained yet inherently fragile balance. It reflects a shared recognition among the parties involved of the catastrophic costs of full-scale war, while simultaneously exposing the inadequacies of existing mechanisms for conflict resolution. There is no comprehensive framework in place capable of addressing the underlying tensions in a sustained and credible manner.
Thus, the Strait of Hormuz today is more than just a geographical chokepoint. It has become a prism through which the complexities of the contemporary international system are refracted. It reveals a world characterized by deep interdependence alongside persistent mistrust, where major powers and regional actors alike engage in continuous strategic signaling, testing limits without entirely breaching them. In such a system, stability is not the product of resolution but of restraint — and even that restraint is contingent, uncertain, and subject to sudden reversal.
