The Calculated Clash Between the United States and Iran: To What Extent Has the Pattern of Hostility Been Broken and a Stable System of Mutual Deterrence Established?

The idea that a prolonged conflict can be broken through a “calculated shock” is not new in political history, but it remains one of the most sensitive and complex ideas, as it always stands on the fine line between reshaping the regional order and sliding into wider chaos. In the case of chronic tension between the United States and Iran, we are facing an extended model of “conflict management” rather than resolution: decades of indirect deterrence, proxy wars, undeclared confrontations, and blurry red lines constantly tested without being fully crossed.

This pattern was not a product of weakness, but rather a result of precise strategic calculations. Confronting a country the size of Iran, with its geographical and demographic depth, its network of regional relations, and its ability to respond disproportionately across multiple arenas, made any thought of a comprehensive war an extremely costly option. Therefore, successive US administrations preferred a policy based on containment and deterrence, keeping the conflict within a relatively low level of escalation, through indirect economic and military tools, proxy wars, and constant tension management without reaching a breaking point.

However, this very “inconclusiveness” is not without cumulative cost. A state of continuous hostility without a comprehensive war gradually produces an environment of slow attrition: a permanent arms race, chronic regional tension, and an expansion in the maneuvering space for non-state actors who find in this ambiguity room for influence. Thus, the situation turns into an unstable equation: no one achieves a decisive victory, but everyone loses stability.

From this perspective, the shift being discussed, especially in the context of more impulsive policies attributed to the Donald Trump administration, can be understood as an attempt to break this entrenched pattern. The idea here is not to go to a comprehensive war, but to raise the level of friction to a degree that forces both parties to directly test the limits of power. Instead of calculations remaining theoretical or based on uncertain estimates, there becomes practical friction, even if limited, revealing each party's ability to withstand, respond, and impose a threat ceiling.

This shift cannot be understood solely as escalation, but also as a process of managing escalation itself. What emerged in this context was the ability of the United States, as the main active power, to keep the war within “controlled” limits and prevent it from spiraling into a comprehensive war. At the same time, Iran showed equally important behavior: precisely calculated responses, controlled escalation, and avoidance of sliding into reckless reactions despite pressures and escalatory statements. This mutual behavior was not merely self-restraint, but a result of a practical mutual understanding of the danger of losing control.

More importantly, this interaction produced something akin to “unwritten rules of engagement” that formed during the testing itself, not before. And here a pivotal point emerged: that the war or friction did not get out of control, but rather transformed into a space for redefining the limits of possible action. In this sense, Iran was no longer merely a targeted or contained party, but became a regional actor whose responses were precisely calculated, giving it the position of an “unignorable peer” without implying recklessness or slippage. In return, this dynamic reshaped Washington's own calculations, to deal with Iran as a power whose ability to influence and deter cannot be underestimated.

Within this framework, the United States also played an additional role that was not limited to direct confrontation, but also to regulating the regional rhythm, including managing Israel's behavior and preventing its slide into uncalculated escalation. This role made Washington not only a party to the conflict, but also a regulator of the limits of its escalation, thereby maintaining the ability to control its overall trajectory.

This “forced clarity” that arose from mutual testing reshaped the logic of deterrence itself. Instead of being based on assumptions, it became based on actual experience. Each party became more precisely aware of the other's limits: what can be endured, what can be responded to, and what can lead to a comprehensive escalation. Here, ambiguity turns into clarity, but it is a clarity fraught with risks, because it produces stability based on experience, not on trust.

In this context, drawing an analogy to the post-1973 October War experience between Egypt and Israel becomes analytically tempting. Before that war, there was a pattern of attrition and unresolved hostility. But the war itself broke the stalemate, redefined the balance of power, and later paved the way for the Camp David Accords, which established a relatively stable system of relations, even if it remained cold in nature. However, the fundamental difference is that the US-Iranian situation is more complex, because it is multi-arena, including the Gulf, Iraq, Syria, Lebanon, and maritime passages, in addition to non-state actors capable of escalating beyond the direct control of states.

Despite these differences, the scenario that logically emerges in this analysis is the transition from a managed conflict to a tested conflict, and then to a stable system of mutual deterrence. In this system, traditional peace is not achieved, but implicit rules are formed: clear red lines, non-overlapping spheres of influence, and communication channels, even informal ones, to avoid misunderstanding. Over time, this could lead to an “extended cold peace,” where trust is absent, but the probabilities of comprehensive war are reduced.

However, this path cannot be considered inevitable. There are structural risks that could return it to chaos: miscalculation that could turn limited friction into widespread escalation, the autonomy of proxies who could drag parties into unintended confrontations, internal political changes that could redefine strategic calculations, and finally, a breakdown of deterrence if any party feels that the other has lost the ability or will to respond.

In the end, what is forming is not just a military or political confrontation, but a transitional moment in the nature of the regional order itself: from a long hostility managed by ambiguity, to a hostility tested by friction, and from hypothetical deterrence to experienced deterrence. If this transformation succeeds in establishing its rules, it could lead to long-term stability based on managing power instead of denying it. If it fails, breaking the pattern could become the beginning of a new and more complex cycle of repeated escalation.

In this sense, the essence of the conflict lies not only in the balance of power, but in the ability to transform the test of power itself into a structure of stability, rather than it becoming a prelude to a long-term unraveling.
