Iran’s Strategic Pivot: From Nuclear Program to Control of the Strait of Hormuz

Iran has acted on its long-standing threat to close the Strait of Hormuz, prompting the United States to respond with a naval blockade. Despite skepticism over the legality, feasibility, and efficacy of the initial move—and the reversal in maintaining the blockade—the immediate global impact—soaring oil prices and market turmoil—appears to have surprised even Iran, judging by reactions from pro-regime circles on state media and social networks.

An idea once dismissed as grandstanding or a doomsday scenario has become a weapon of disruption, potentially more powerful than the weapons of mass destruction Iran was suspected of pursuing.

Until the U.S. attack in June 2025 on Iran’s main nuclear fuel production facilities, the Islamic Republic had spent billions of dollars on research, construction, and protection of its nuclear program, while sacrificing billions more in income and opportunities due to the isolation and sanctions the program provoked.

The nuclear file also fueled political repression at home. Since 2005, the deepest rifts between moderates and hardliners have revolved around the program and its mounting costs. Most presidential elections after 2005 became referendums on the nuclear file and how to manage its fallout. Much of the opposition to the autocratic power of Supreme Leader Ayatollah Ali Khamenei stemmed from his insistence on maintaining the costly project and accepting the distortions it imposed on the economy.

Any figure or faction that criticized the program and advocated diplomacy was gradually purged. By 2021, after most reformists and moderates were barred from running for president, even Khamenei’s longtime adviser Ali Larijani (later assassinated by Israel in March 2026, shortly after Khamenei was killed) was excluded, largely because of his role as parliament speaker in pushing the 2015 Joint Comprehensive Plan of Action (JCPOA).

Evidence from the recent U.S.-Israel attack does not yet point to a completed doctrinal revolution, but a genuine internal debate is underway about whether control of the strait can replace nuclear capability as Iran’s primary deterrent. Iran’s proposal in talks with Pakistan to suspend uranium enrichment for several years is significant. Even if tactical and temporary, it suggests that parts of the Iranian state no longer view enrichment as the inviolable core of strategy, and are willing to elevate leverage based on Hormuz and maritime disruption as a substitute.

Other signs point in the same direction. Since succeeding his father, the new Supreme Leader Mojtaba Khamenei has not mentioned the nuclear program once in his public statements. Instead, he has consistently emphasized Iran’s right to manage the Strait of Hormuz.

The far-right populist wing of the hardline faction, represented by former nuclear negotiator and national security adviser Saeed Jalili and the Paydari (Steadfastness) Front, appears less fixated on the nuclear issue. Foad Izadi, a key analyst for this camp, did not mention it during a 50-minute appearance on state television, instead extolling the Strait of Hormuz as a source of revenue greater than oil exports. “How much longer must we chase the Americans and beg them to lift sanctions?” he asked. “Now India, as a buyer of Iranian oil, must lobby the U.S. Congress to lift sanctions so it can pay.”

More pragmatic conservatives, close to parliament speaker and nuclear negotiator Mohammad Bagher Ghalibaf, have begun to justify suspending enrichment after the June 2025 airstrikes on Iran’s underground facilities, floating the idea of a “nuclear sunset” in exchange for greater investment in the oil sector. They are now openly questioning the deterrent value of the threshold status and arguing for a shift toward maritime control. “Enrichment, which was never a strong lever,” wrote Jalil Mohebbi, a senior adviser to Ghalibaf, “is now replaced by the Strait of Hormuz, which cannot be bombed, oxidized, or filled with cement.”

Regardless of the outcome of U.S.-Iran talks, two consecutive attacks on Iran’s top political and military leadership, along with military, security, and civilian infrastructure, have made one thing clear: the nuclear threshold state has not only failed to provide deterrence but may have weakened Iran’s conventional defense assets.

If the Hormuz faction consolidates its position, the consequences for Iran’s domestic politics and the broader region could be significant. The nuclear file made it easy for hardliners to define patriotism, stigmatize dissent, and concentrate power in the security state. Shifting from nuclear to Hormuz could undermine the hardliners’ justification for purging reformists on national security grounds and open wider space for elected bodies and civil society. It would also vindicate those who long argued that Iran’s leverage lies in geography, trade, and diplomacy rather than military-technological power, empowering diplomats and technocrats over military ideologues.

A maritime doctrine would also shift Iran’s strategic focus toward the Gulf and its southern coast. Ports, shipping, customs, logistics, and energy transit would become more important than domestic prestige projects tied to the nuclear security complex. Southern Iran would gain economic and political weight.

Culturally, such a shift could begin to loosen the grip of Cold War paradigms and Shiite revolutionary narratives that have long defined the Islamic Republic’s worldview. The name Hormuz, in Persian tradition, evokes Ohrmazd or Ahura Mazda, the Zoroastrian deity of wisdom and order. A pivot to Hormuz would not erase the revolutionary worldview, but could begin to supplant it with a different language: of territory, exchange, geography, and state interest.

Regionally, a Hormuz-centered order could push the Gulf monarchies toward compromise rather than confrontation. Maritime security arrangements, conflict prevention channels, and transit frameworks would become more attractive, and Iran’s relations with its Arab neighbors could become less ideological.

Finally, the shift could gradually ease the existential anxiety Israel harbors toward Iran. A nuclear posture narrows distances and fuels fears of annihilation; in contrast, the Strait of Hormuz is too far from Israel and too passive a deterrent to provoke a similar panic. Israel might still view Iran as hostile, but less as a direct threat, making conflict more indirect, regional, and containable.

What this war may reveal is not simply Iran’s resilience, but the exhaustion of the strategic doctrine through which the Islamic Republic has defined itself for much of the past generation. If Iran’s most effective leverage now lies less in nuclear capability and more in the hard facts of maritime geography, outside powers should be cautious not to recreate the old nuclear stalemate in a slightly modified form.
