The US blockade of Iran moves onto land: Task Force Iron Gate targets the borders and the Caspian as talks stall

The United States has set up a new military task force to cut Iran’s overland supply lines, extending a blockade that until now has been fought at sea.

US Central Command (CENTCOM), which runs American forces in the Middle East, announced Task Force Iron Gate on Saturday 7 November, US time. Its commander, Admiral Brad Cooper, said in a statement on X that the 20-member team of civilian and military staff, based in Florida, will work with other US government agencies to stop advanced weapons, dual-use technologies, sanctioned materials and illicit revenue moving across Iran’s land borders and the Caspian Sea.

Admiral Cooper said the task force “will further constrain Iran’s ability to finance terrorism, rebuild weapons factories, and replenish their military”.

Donald Trump followed with a Truth Social post saying “Task Force Iron Gate is in full force and effect in the Islamic Republic of Iran.”

Why go after land routes now?

Because the sea is largely closed. US forces have blockaded movements to and from Iranian ports for months, and CENTCOM says the blockade has halted about US$25 billion in Iranian crude exports, with humanitarian aid exempt.

What the navy cannot touch is the rest of Iran’s map. The country shares land borders with Iraq, Turkey, Armenia, Azerbaijan, Turkmenistan, Afghanistan and Pakistan, and the Caspian Sea links its northern ports to Russia and Central Asia. Those are the routes a blockaded economy turns to, and the routes by which components for missiles and drones can arrive.

A 20-person team in Florida will not patrol those borders. Its weight lies in the agencies it coordinates: sanctions, financial tracking and pressure on the companies, banks and governments that handle Iran’s trade.

What has Iran said?

The Islamic Revolutionary Guard Corps dismissed the plan as “wordplay”. Guards spokesman Hossein Mohebi said it “will fail” and would not cause economic collapse, because Tehran had made preparations and was coordinating closely with its neighbours.

Where do the talks stand?

Stalled, but not dead. Iran’s Foreign Minister Abbas Araghchi said mediators had not travelled since the US midterm elections, which he called a “shock”, and that it would take time before conditions favoured new trips.

Iran has sent a nuclear proposal through Qatar, which a senior Iranian official said Washington is reviewing, but Tehran says talks depend on seven demands being met first, including sanctions relief, access to frozen assets and war reparations. Qatar has denied reports that the talks have failed.

Mr Trump, asked whether he would order new strikes, said it depends on whether Iran signs “a very strong agreement”, adding that strikes were “highly unlikely” to be needed.

What does it mean for Australians?

The price of the Iran war shows up at Australian bowsers. Oil had its biggest weekly fall since the pandemic last week on hopes of a deal, and any sign that Washington is tightening rather than easing the squeeze can push it back up.

Prime Minister Anthony Albanese has said he will raise the Iran war with Mr Trump at the Quad meeting in Manila and engage with him “respectfully”, making Australia one of the allies watching closely whether pressure or diplomacy comes first.
