Iran’s attacks in and around the Strait of Hormuz are commonly reported as episodes: a drone intercepted, a merchant vessel threatened, a warship attacked, a civilian terminal struck. Those events matter, but events alone do not explain strategy. Targets do.
Political violence is best understood first through the target selected rather than through the identity, rhetoric, or grievance claimed by the attacker. A drone directed at a warship is an instrument of warfare. The same drone deliberately directed at civilians for psychological and political effect tells a different moral and strategic story. A missile aimed at a military installation is not analytically identical to one aimed at a passenger terminal. Target selection reveals intent.
This approach clarifies Iran’s present campaign against the United States and its regional partners. Tehran is not merely escalating; it is selecting different targets for different effects. Military forces are attacked to impose operational costs and test response thresholds. Commercial shipping is threatened in order to generate economic pressure. Civilian infrastructure is struck to widen fear and political urgency. Proxy-accessible targets expand the conflict while limiting Iran’s direct exposure.
That is asymmetric warfare in the form most relevant to American strategy. It is not simply a contest between a weaker and stronger actor. It is the deliberate avoidance of the stronger power’s advantages in favor of vulnerabilities that military superiority cannot easily protect. Iran does not have to defeat the US Navy in open combat. It has to make the defense of free navigation costly, dangerous, politically contentious, and eventually negotiable.
The connection to October 7 is direct. The central lesson of Hamas’s attack was not merely that intelligence systems can miss danger. It was that a powerful state can possess information and still fail because it cannot revise the assumptions through which it interprets the threat. Israel knew Hamas was hostile, armed, and committed to the Jewish state’s destruction. What it failed to assimilate was the form that intent might take. Containment became a substitute for understanding.
Iran’s conduct in the Strait of Hormuz tests whether the United States has learned the corresponding lesson. A weaker adversary need not match American power if it can choose the targets, dictate the tempo of response, and turn American strength into a recurring protection obligation. The question is not merely how many Iranian weapons are intercepted. It is whether Tehran’s targeting strategy is permitted to produce leverage.
Read Iran by its Targets
Iran’s recent actions reveal the structure of its strategy. Iranian missiles, drones, and small boats have been directed at American warships transiting Hormuz. One-way attack drones have been launched toward civilian mariners in regional waters. Iranian attacks have also reached civilian infrastructure in Gulf states, including the strike that damaged a passenger terminal at Kuwait International Airport and killed a civilian.
These are not interchangeable incidents.
An attack on an American destroyer or a military facility is asymmetric interstate warfare. The target is military. The objective may be to destroy capability, complicate operations, impose protection costs, or probe the American threshold for escalation, but it is asymmetric because Iran is not matching the US conventional military directly. Such an attack is not terrorism merely because Iran is weaker or because the act is aggressive. Analytic precision matters: a military target remains a military target.
However, commercial maritime targets present a different strategic logic. Threatening merchant ships, civilian mariners, or passage through Hormuz is not principally a way to defeat the US Navy. It is a way to manipulate the economic and political consequences surrounding naval protection. Iran can make shipping dangerous, force the use of escorts, increase insurance costs, delay energy flows, unsettle markets, and encourage commercial and diplomatic pressure for an accommodation that restores normal transit.
That is maritime coercion. When the victims are civilians deliberately selected to frighten a wider audience or compel political behavior, the method also enters the logic of terrorism: violence against noncombatants for communicative effect.
The same is true of civilian infrastructure. A passenger terminal is not equivalent to a destroyer or a missile battery. When civilians are deliberately placed in the target set, the physical destruction is only part of the purpose. The wider object is to broadcast vulnerability: to tell governments, travelers, investors, and regional partners that alignment with the United States carries a direct human cost.
Iran’s proxies broaden this strategy. Hezbollah, the Houthis, and Iranian-aligned militias provide Tehran with the means to disperse pressure, expand geography, and blur the path of retaliation. Depending on the chosen target, proxy attacks may function as military pressure, maritime coercion, or terrorism. The key point is that proxy violence is not separate from Iran’s approach; it is one of the mechanisms through which Tehran transforms regional vulnerability into leverage.
Viewed by target type, the pattern is coherent. Military attacks seek operational constraints. Maritime attacks seek economic pressure. Civilian attacks seek to instill fear and create political urgency. Proxy attacks seek reach without equivalent exposure. These are not scattered tactics. They are an integrated strategy.
Hormuz and Converting Weakness into Leverage
The Strait of Hormuz is especially valuable to Iran because geography multiplies the effect of limited capabilities. The passage is narrow, economically indispensable, difficult to secure completely, and exposed to weapons far cheaper than the architecture required to defend against them.
Before the current conflict, nearly one-fifth of the global oil supply moved through the Strait of Hormuz. Once passage became dangerous or uncertain, the consequences extended far beyond the immediate theater. The US Energy Information Administration reported that the effective closure of the strait pushed Brent crude oil to an average of $117 per barrel in April, $46 above the February average.
This is the economic logic of Iran’s strategy. A drone need not sink a destroyer to succeed. A missile need not close the passage permanently. A mine need not destroy a tanker. Each threat can raise costs, change shipping behavior, compel naval protection, and increase pressure on Washington and its partners to restore normal commerce.
The United States has responded operationally. Project Freedom was established to restore commercial navigation through Hormuz, and American forces have defended naval and commercial transit while striking facilities associated with Iranian attacks. Those actions are necessary. Yet the scale of the American protection mission also illustrates the underlying asymmetry: Iran can impose a global problem using comparatively limited means, while the United States must defend the wider system.
Operational success is not the same as strategic adaptation. The United States can defeat individual attacks and still fail if Iran transforms ordinary passage through an international waterway into a concession to be negotiated. Tehran does not need to win every tactical exchange. It needs to demonstrate that disruption pays.
That was the danger exposed by October 7 in a different arena. Hamas did not need military parity with Israel. It needed to exploit assumptions, seize hostages, murder civilians, trigger war, and drive Israel into a strategic crisis extending far beyond the battlefield. The failure was not due to a shortage of strength. It was a failure to recognize the enemy’s method before that method succeeded.
Containment is not an adaptation if the adversary decides when containment must be enforced.
Nuclear Shadow Behind Iran’s Strategy
Iran’s present conduct also reveals what would become substantially more dangerous if the Islamic Republic obtained a nuclear weapon. Nuclear blackmail is the use of nuclear escalation risk not merely to deter an attack, but to compel an adversary to tolerate aggression it would otherwise stop.
A nuclear weapon would not require Iran to abandon its existing asymmetric strategy. It would shield and amplify it.
Consider an extreme but analytically necessary scenario. If Iran launched a nuclear strike against a concentrated American naval force in or near Hormuz, the immediate target would be military. In target-centric terms, the act would be catastrophic interstate warfare rather than terrorism directed at civilians. Yet Washington would still confront a nearly intolerable dilemma: retaliate at a level sufficient to restore deterrence and risk uncontrolled nuclear escalation, or respond more cautiously and risk demonstrating that nuclear first use successfully restrained American power.
Israel would face an equally grave challenge. Tehran might describe a nuclear strike against the Dimona nuclear complex as an attack on a strategic or “dual-use” target. But a rhetorical designation cannot sanitize foreseeable civilian and radiological consequences or obscure the coercive purpose of the attack. The objective would be not only destruction, but paralysis: forcing Israel to weigh its survival against the consequences of meaningful retaliation.
The danger is not that Iran is certain to choose national suicide, nor that deterrence invariably fails against ideological regimes. The danger is assuming that Tehran defines rationality, sacrifice, and survival as American or Israeli decision-makers do. Deterrence depends on an opponent judging the threatened consequences of aggression unacceptable. A revolutionary regime may accept levels of national suffering or regime risk that Western analysts regard as self-defeating, particularly if its leaders believe they are delivering a historic blow against Israel or the United States.
October 7 exposed the cost of dismissing openly declared intent because its execution seemed irrational. A nuclear-armed Iran would place that same failure of imagination under a nuclear shadow.
Proxies, Deterrence, and Adaptation
A nuclear capability would also alter the environment in which Iran’s proxies operate. Hezbollah, the Houthis, and Iranian-aligned militias already allow Tehran to attack across multiple fronts while controlling, or attempting to control, its own direct exposure. Under a nuclear umbrella, those actors could become more aggressive precisely because retaliating directly against their sponsor would carry heightened escalation risks.
The danger is not that every proxy attack would become a nuclear crisis. It is that nuclear capability could normalize greater Iranian aggression beneath the nuclear threshold. Attacks once treated as intolerable could be reclassified as manageable. Responses once regarded as necessary could appear too dangerous. The stronger actor would begin to adapt not by defeating coercion, but by accommodating it.
The answer is neither reckless escalation nor the abandonment of moral restraint. Democracies that discard their values in the name of adaptability have merely changed the form of their failure. But restraint is not passivity. It cannot mean allowing Iran to build a durable political return from coercion.
Freedom of navigation through Hormuz cannot become a privilege granted by Tehran. Iranian military attacks must meet credible military deterrence. Deliberate attacks on civilians and civilian shipping must be recognized for their coercive and, where applicable, terrorist logic. Proxy operations must be treated as components of Iran’s strategic system rather than as disconnected regional disturbances. Above all, the nuclear issue cannot be separated from Iran’s present method of warfare: a nuclear capability would not replace its asymmetric strategy, but protect and expand it.
Success should therefore be measured not only by what American or allied forces destroy, but by what Iran fails to achieve. If Tehran cannot close Hormuz, cannot condition commercial passage, cannot shelter proxy escalation, and cannot use nuclear fear to limit legitimate defense, then its strategy has failed.
Iran cannot defeat the United States in conventional naval warfare. That was never the point. Its purpose is to turn American strength into obligation, obligation into hesitation, and hesitation into leverage.
The United States has demonstrated it can operate in and around the Strait of Hormuz. The test now is whether it can learn there, before maritime coercion becomes nuclear blackmail, and before another adversary’s method succeeds because the stronger actor refused to imagine it in time.
