US Threatens Indefinite Naval Blockade of Iran as Tensions Escalate

The United States has warned that it could maintain a naval blockade against Iran indefinitely as ceasefire negotiations between Washington and Tehran remain deadlocked.

US Defense Secretary Pete Hegseth said the US Navy could sustain its presence in the region by rotating ships in and out. Meanwhile, Treasury Secretary Scott Bessent announced plans for tougher economic measures aimed at further isolating Iran.

The threat comes amid continued uncertainty over the Strait of Hormuz, a crucial global oil-shipping route. Iran maintains that the waterway remains blocked and says it will not reopen it until its demands, including the lifting of the US naval blockade and sanctions, are met.

Concerns Over US Aircraft Carrier

The ability of the US Navy to sustain a prolonged blockade has also come under scrutiny following reports about conditions aboard the USS Abraham Lincoln, which has been deployed at sea for an unusually long period.

US lawmakers have raised concerns over alleged declining morale, mental-health problems, shortages of basic supplies, water contamination and other operational difficulties aboard the carrier.

Hegseth has rejected reports of deteriorating conditions, while US Central Command denied claims that seven sailors had died in a fight aboard the ship. CENTCOM said no service members aboard the carrier had died and confirmed that a sailor who fell overboard on August 3 was safely recovered.

Military experts, however, say aircraft carriers require regular maintenance in port. Retired naval officer Harlan Ullman warned that prolonged deployments could gradually reduce a ship's readiness and operational capability.

Iran Faces Growing Economic Pressure

Washington hopes the blockade will further weaken Iran's economy by restricting its ability to export crude oil, one of the country's main sources of revenue.

Iran has already reportedly lost billions of dollars in oil revenues since the blockade began. US President Donald Trump has argued that Iran is under severe financial pressure and has indicated that Washington prefers economic pressure to another major military offensive.

Iran, however, may have several ways to respond.

Experts say Tehran could target US naval assets or encourage its allies, including the Houthis in Yemen, to increase pressure on regional energy exports.

Iran also views the Strait of Hormuz as a major strategic bargaining tool. Its officials say they maintain control over movements through the waterway and have warned that it will remain closed until their conditions are met.

Can the Blockade Continue Indefinitely?

Although the US has the naval capacity to rotate forces and maintain pressure on Iran for an extended period, analysts say sustaining such operations indefinitely would create significant logistical, maintenance and personnel challenges.

Iran is also under substantial economic pressure, but analysts argue that its political leadership may be willing to endure economic hardship in order to remain in power.

The standoff therefore risks becoming a prolonged contest of economic and military endurance, with control of the Strait of Hormuz remaining one of Iran's most powerful sources of leverage.
