Trump shifts Iran strategy towards economic pressure

The Trump administration is ramping up economic sanctions against Iran as Washington seeks alternative means to compel Tehran to negotiate a political settlement, following months of military operations. The strategy includes stricter sanctions on oil exports and a renewed naval blockade, while maintaining the threat of further strikes.

The administration appears to be prioritizing the weakening of Iran's capacity to fund its military and regional operations over sustained bombing. With the conflict entering its sixth month, Iran's leadership remains unyielding and negotiations over a permanent deal have stalled. Washington believes economic pressure may prove more effective than military force.

Over 1,000 people, ships, and aircraft have been targeted under the intensified "maximum pressure" campaign, which encompasses oil trading networks, financial channels, weapons procurement, and shipping operations. Iran's oil revenue is the primary target, as hydrocarbon exports constitute a significant portion of Tehran's foreign currency earnings.

US officials aim to curtail these revenues through financial sanctions and maritime enforcement, tying sanctions relief to concessions from Iran. However, the strategy poses risks. Iran has proven capable of inflicting costs on the US and its allies by disrupting shipping through the Strait of Hormuz, a critical waterway that once handled about one-fifth of global oil and liquefied natural gas flows.

An interim agreement signed in June aimed to end military operations and create a 60-day window for negotiations on Iran's nuclear program and sanctions relief, but it quickly fell apart. President Donald Trump revoked the agreement on July 7 while Iran subsequently suspended it, leading to accusations from both sides of violating the terms.

Iran alleges the US failed to lift the blockade on its ports and release frozen assets, while the US contends that Iran did not reopen the Strait of Hormuz. The lack of progress in reviving the framework has kept both economic warfare and military escalation on the table.

The strain on US military resources has also played a role in Washington's decision-making. More than 20 Navy warships and hundreds of aircraft have been deployed to the conflict, with the Pentagon grappling with weapon inventory, maintenance, and capacity concerns. Joint Chiefs Chairman General Dan Caine briefed the administration on the risks associated with drawing weapons from stockpiles assigned to other theaters.

President Trump has dismissed suggestions of a munitions shortage but acknowledged the pressure on inventories as part of the broader discussion on the sustainability of intensive operations.

The financial toll of the war is another constraint, with Defense Secretary Pete Hegseth informing lawmakers that the conflict has cost around $37.5 billion, and additional funding requests in the tens of billions. The loss of 18 US service members and over 430 wounded, along with thousands of casualties on the Iranian and Lebanese sides, has added to domestic political challenges.

Support for the conflict has dwindled, with only 35% of Americans backing the war in an August poll, while half anticipated increased chaos in the Middle East and just 17% believing it would lead to stability. Rising fuel costs have further exacerbated voter concerns as Republicans prepare for the November midterm elections, highlighting the competing pressures on both sides.
