Nournews: One of the most important—and perhaps least understood—aspects of Iran’s behavior during the recent war with the United States was the way it managed its “strategic messaging.” In wars, what ultimately shapes the course of events is the kind of signal that actors send to their enemies, allies, and the regional environment. During this crisis, Iran attempted to convey two seemingly contradictory, yet in fact complementary, messages simultaneously: first, that it does not fear the expansion of the battlefield and is prepared to regionalize the conflict; and second, that it is not seeking the permanent destabilization of the region and genuinely believes in regional cooperation. This duality formed the core of Iran’s strategy of regionalizing the war.

We Did Not Send a Signal of “Fear”

When Iran declared that it would regionalize the war and that any country participating in operations against Iran would expose itself to an Iranian response, it was effectively defining a new deterrence doctrine. The meaning of this message was that a war against Iran could no longer remain a limited and low-cost operation. In other words, regional states could no longer benefit from participation in an anti-Iran coalition while remaining immune from its consequences.

In the past, many regional actors assumed that a confrontation between the United States or Israel and Iran would be a “distant war” for the countries of the region—a war in which they merely facilitated operations rather than becoming part of the battlefield itself. However, through direct attacks and the expansion of the scope of retaliation, Iran altered that perception. This was precisely the point at which the policy of regionalizing the war acquired meaning: transferring the costs from the center of the conflict to the entire network of participants.

This strategy was not merely a military measure; it also constituted a psychological and geopolitical operation. Iran sought to instill in the minds of regional states the idea that the security of the Persian Gulf is indivisible. If Iran becomes insecure, no actor in the region will enjoy lasting security. In practice, this logic created a form of “enforced mutual security interdependence.”

Within this framework, the Strait of Hormuz gained particular significance. For years, Iran has emphasized its geopolitical position along this strategic waterway, but during the recent crisis, the issue went beyond rhetorical threats and became part of Iran’s demonstration of political resolve and sovereign authority. The message was clear: Iran still possesses the capacity to influence the world’s energy artery and can globalize the costs of any confrontation.

We Did Not Send a Signal of “Aggression”

More importantly, Iran simultaneously attempted to balance this assertive behavior with a softer political message: the renewed idea of regional collective security. This aspect of Iran’s strategy received less attention, yet diplomatically it may have been even more significant. Tehran was effectively trying to tell regional countries: “If you join a coalition against us, you will bear the costs; but if you accept the logic of regional cooperation, Iran is not a threat to you.”

Here, we are confronted with a sophisticated game of signaling. In the literature of international relations, states are often trapped between two dangers: either they appear overly conciliatory and send signals of weakness and fear, or they act so aggressively that they send signals of hostility and threat, pushing others toward forming coalitions against them. Strategic skill lies in creating a balance between deterrence and reassurance. During this crisis, Iran managed to construct such a balance.

Iran did not want to send a signal of fear, because in the Middle East, fear is often interpreted as an invitation for greater pressure. In this geopolitical environment, an actor perceived as weak or hesitant not only fails to gain greater security, but instead faces broader pressures. Tehran therefore sought to demonstrate that in the event of a threat, it was prepared to expand the battlefield and had no hesitation in using its geopolitical leverage.

At the same time, however, Iran did not wish to be perceived as an expansionist and uncontrollable power. For this reason, it emphasized the concepts of collective security and regional cooperation in order to convey that its objective was not regional domination, but rather preventing the region from becoming a permanent launchpad for operations against Iran.

This is precisely the delicate and complex point that many analyses fail to grasp. In this crisis, Iran was not merely seeking to display military power; it was attempting to redefine the rules governing regional perceptions of security. Tehran sought to establish the equation that regional security must either be “shared” or it will not exist at all.

In effect, Iran attempted to connect “hard deterrence” with an “invitation to cooperation.” On the one hand, it demonstrated its capability and determination to respond; on the other hand, it stressed that the path toward reducing tensions lies in regional participation and the abandonment of imported security models. This combination is what may be called the policy of “neither signaling fear nor signaling aggression.”

Of course, the ultimate success of such a strategy depends on the future behavior of regional actors and extra-regional powers. If regional countries continue to define their security solely through alliances with foreign powers, the likelihood of recurring crises will remain high. But if the understanding emerges that any war against Iran would destabilize the entire region, then perhaps the idea of collective security may evolve from a slogan into a geopolitical necessity.

Perhaps the most significant achievement of Iran’s recent strategy lies not on the military battlefield, but in changing the region’s strategic calculations. Iran attempted to show its neighbors that the era of a “low-cost war against Iran” has come to an end. At the same time, however, it left the door open for the region to choose cooperation and shared security instead of confrontation.
