Iran War Stalemate Shifts From Missiles to Sanctions

Six months after fighting began, the Iran war stalemate has settled into a new and costly phase, as Washington shifts from airstrikes to economic warfare while Tehran bets that time is on its side.

From missiles to sanctions

Six months after U.S. and Israeli forces attacked Iran, killing its supreme leader and wounding his son and successor, Iran’s government remains under economic siege but still holds power, believing it can outlast the pressure.

President Donald Trump’s threat of crippling new sanctions faces a core problem: Tehran is betting he won’t take the final step of aggressively enforcing secondary sanctions on the countries keeping its economy afloat, chiefly China and India.

Washington’s latest measures, announced Monday, mark a new phase in a conflict that began February 28, shifting the battlefield from missiles and airstrikes to Iran’s oil revenue, banks and trading partners. Treasury Secretary Scott Bessent said the U.S. will cut off the financial lifelines sustaining Iran’s economy, while a U.S.-led naval blockade restricts Tehran’s oil exports and access to hard currency.

“The [Trump] administration is groping in a sort of desperate fashion to try to find a pathway out of this,” said Aaron David Miller, a former U.S. diplomat and senior fellow at the Carnegie Endowment. Bessent compared the sanctions rollout to the 1944 D-Day landings, but Miller pushed back: “To me, this isn’t D-Day. It’s Desperation Day. I don’t think the administration is any closer to finding a way out of this.”

A blockade with bigger stakes than sanctions

Michael Knights, head of research at Horizon Engage, a New York-based strategic advisory firm, said the naval blockade may prove more consequential than the sanctions themselves, since Iran’s immediate challenge is no longer surviving economic pressure but breaking out of it.

Tehran has spent decades adapting to sanctions and endured previous “maximum pressure” campaigns without changing its behavior, Knights said. Rising economic pressure, he added, may push Iran to raise the cost of the confrontation for its adversaries by leaning on Gulf states, particularly Saudi Arabia, to nudge Washington toward a diplomatic exit.

Knights said Iran could increasingly follow the model used by its Houthi allies in the Red Sea: periodic attacks, intermittent negotiations and prolonged disruption short of all-out war, potentially targeting shipping, ports or energy infrastructure to raise the cost for Gulf states.

Washington disputes that reading. “The Iranian economy is in free fall and the regime’s military has been decimated,” State Department spokesperson Tommy Pigott said. “President Trump holds all the cards, and we are cutting off every financial lifeline the regime has remaining.”

Iranian officials call the strategy a rerun

Alan Eyre, a former U.S. diplomat who worked on Iran, questioned whether Washington has the international support and bureaucratic machinery to make the sanctions stick. Unlike the multilateral campaign that preceded the 2015 nuclear deal, he said, the latest measures rely on public threats rather than sustained diplomacy with allies and trading partners.

Iranian officials dismiss the U.S. approach as a repeat of a failed playbook. A senior Iranian official told Reuters that countries such as China would not stop cooperating with Iran simply to serve U.S. interests. Some analysts note a deeper flaw: from North Korea to Russia to Iran, sanctions have rarely forced governments to abandon goals they consider existential.

The senior official said Tehran believes Washington’s real goal is to fuel domestic discontent, but that the “maximum pressure” campaign failed once during Trump’s first term and would fail again. “If the pressure increases, Iran’s approach will change too,” he said, adding that Gulf Arab governments understand that squeezing Tehran further could put them at risk as well.

Unrest looms as a bigger threat than economic pain

For Iran’s rulers, the deeper danger may not be economic hardship itself but the risk it reignites mass unrest, according to insiders and an Iranian official. Annual inflation hit 66% in July, with consumer prices up 87.9% from a year earlier and food prices up 128%, according to Iran’s Statistical Centre.

President Masoud Pezeshkian acknowledged the strain last week: “Our problems have multiplied several times over, while our income has also fallen.” Economic grievances have repeatedly triggered nationwide protests in recent years; demonstrations in January were crushed by the Revolutionary Guards and Basij militia, with thousands killed.

The appointment this month of Hossein Taeb, a key architect of past crackdowns, to lead the Basij was one of the clearest signs yet of official concern about renewed unrest, a former reformist official said. That points to a paradox in Washington’s strategy: sanctions may deepen Iran’s economic pain without forcing its rulers to change course, since the leadership has historically met domestic unrest with repression and outside pressure with threats of retaliation.

Gulf states fear a dangerous impasse

For Gulf states, the calculation is especially fraught. They prefer economic and diplomatic pressure over renewed war, but fear an outcome that lets Iran claim victory while retaining the ability to disrupt the Strait of Hormuz, a vital oil route Tehran has effectively blocked, pushing up global oil prices.

Abdulaziz Sager, chairman of the Saudi-based Gulf Research Center, said Gulf governments doubt sanctions alone can quickly change Iran’s behavior, given the leadership’s resilience and grip on internal control. Significant political change, or the collapse of Iran’s theocratic government, is unlikely to come soon, he said.

The result is a dangerous impasse if mediated talks fail to produce a breakthrough: Washington wants Iran to give up its leverage over Hormuz without granting Tehran a role in managing the waterway, Iran wants the naval blockade lifted without appearing to surrender, and Gulf states want the conflict contained without letting Iran emerge as the victor.
