US Claims Iran Blockaded, But Can New Task Force Halt Weapons Smuggling?

United States Central Command (CENTCOM) chief Brad Cooper was observed on a commercial vessel transiting the Strait of Hormuz, flying in a US Army CH-47 Chinook helicopter over the international waterway. This observation was provided by [Handout/US Central Command].

In a characteristic display of his usual style, United States President Donald Trump asserted that the US had effectively sealed Iran off from the global community. "Very little gets into, or out of, Iran!" Trump posted on his Truth Social account on Sunday. This statement followed the US Central Command's (CENTCOM) announcement of a new initiative to disrupt Tehran’s military supply chains.

On Sunday, CENTCOM revealed the establishment of Task Force Iron Gate, a unit specifically designed to target land routes and the Caspian Sea. Its objective is to prevent Iran from utilizing ground routes for the transportation of advanced weaponry and other critical materials. President Trump's Truth Social post claimed the task force was already operational in Iran, and combined with the existing US naval blockade of the strategic Strait of Hormuz, had virtually severed the country's import and export channels.

However, analysts suggest that a small, intelligence-focused unit is insufficient to seal Iran's borders or dismantle its extensive procurement networks without crucial regional cooperation. They also cautioned that efforts to disrupt these networks could inadvertently draw neighboring countries into the conflict and jeopardize ongoing diplomatic efforts related to the US-Israel stance on Iran.

Andreas Krieg, an associate professor of defence studies at King’s College London, commented to Al Jazeera, "I see Task Force Iron Gate as a desperate attempt to extend the American naval blockade into Iran’s continental supply networks without deploying American troops along its borders."

An ‘intelligence fusion cell’

Task Force Iron Gate is intended to identify the sources of incoming weapons systems, potential interception points, and Iran's methods for transporting energy, according to Michael Mulroy, a former US deputy assistant defence secretary for the Middle East, speaking to Al Jazeera. The unit, headquartered in Tampa, Florida, will collaborate with various US government agencies to prevent the movement of advanced weapons systems, dual-use technologies, sanctioned materials, and illicit revenue streams across Iran’s land borders and the Caspian Sea, as stated by CENTCOM.

Analysts believe the task force could bolster sanctions enforcement, exert pressure on foreign suppliers, and work with partner nations to disrupt smuggling operations. Matthew Savill, director of military sciences at the Royal United Services Institute, indicated that the US mission would likely employ a combination of satellite imagery, drones, intercepted communications, financial intelligence, and intelligence sharing. Savill further told Al Jazeera, "Then, frankly, I would expect some use of force – strikes or discreet ground operations – to confiscate components, whether done by US forces or the Israelis." He added, "They would want to pass some intelligence on and bring legal and economic pressure to bear outside the Middle East if they think dual-use components are coming from the West … but if the target is supplies from Russia and China, that will be tougher."

While CENTCOM's announcement did not explicitly mention Iran's arms trade with Russia, analysts interpret the unit's focus as an attempt to disrupt supply chains that include Russian involvement. US media reports suggest that Russia has supplied drone components and explosives to Iran via the Caspian Sea, and there are claims that Russian technology is aiding Iran's development of advanced supersonic cruise missiles.

Krieg concurred that the task force would utilize a multifaceted approach, describing its function primarily as an “intelligence fusion cell.” He stated, “Twenty people cannot police thousands of kilometres of frontiers. The objective is not necessarily to stop every shipment, but to make Iranian military procurement progressively more expensive, slower and riskier.” Krieg emphasized that the primary obstacle for the US mission is political rather than technological, citing the general unwillingness of Iran's neighbors to cooperate. He explained, “Iraq offers Washington some leverage, but Iranian-aligned networks remain deeply embedded in its economy and security institutions.”

Regarding other neighbors, Krieg suggested that Azerbaijan might offer discreet cooperation, while Turkmenistan would likely be “extremely reluctant” to jeopardize its neutrality or its relationships with Russia and China. Pakistan, he added, is particularly unlikely to participate openly due to its current role in mediating between Washington and Tehran. Turkiye, according to Krieg, also has little interest in transforming its border with Iran into another area of confrontation. “Without these countries’ cooperation, Washington can disrupt individual networks but cannot effectively seal Iran’s borders,” Krieg concluded.

Rami Khouri, a public policy fellow at the American University of Beirut and a non-resident senior fellow at the Arab Center Washington DC, previously told Al Jazeera that Iran's long history as a trading nation makes the US mission exceptionally challenging. “There’s an enormous web of contacts that Iran has had for thousands of years with traders and partners and allies all over the region, especially in Asia – it’s virtually impossible for the US to seal off every one,” Khouri stated. “There are people all over the region who have links with Iran, some very close, some just commercial.”

Mission creep or mission impossible?

Krieg expressed concerns about potential “mission creep,” where the task force’s actions could expand the conflict into new domains. “Intelligence gathering can quickly become pressure for seizures, border closures or military strikes against suspected logistical infrastructure,” he warned. “This would extend America’s economic war into the sovereign territory of neighbouring states.” Krieg anticipates that Iran's response would likely be asymmetrical, involving “intensifying maritime coercion in Hormuz and potentially using the Houthis to increase pressure around Bab al-Mandeb and Saudi Arabia.”

Joe Kent, a former top US counterterrorism official, has argued that the new task force represents an attempt by CENTCOM to undermine ongoing diplomatic efforts. Following the US military's announcement, Kent posted on X, “This is CENTCOM inviting Iran to escalate while the vice president is attempting to negotiate with the Iranians. This is, as CENTCOM calls it, ‘policy by CONOP’, when the military finds a way to subvert the White House without blatantly disobeying the President, by taking actions that will ensure a war escalates or perpetuates.”

Meanwhile, The Wall Street Journal reported that CENTCOM chief Brad Cooper is among several officials, including Defense Secretary Pete Hegseth, advocating for renewed attacks on Iran. Conversely, some analysts contend that the task force will have limited practical impact due to the absence of US access to the Caspian Sea, ground troops, or cooperation from neighboring states. Mahjoob Zweiri, a professor of contemporary history and politics at Qatar University, suggested to Al Jazeera that the initiative might be largely symbolic due to the lack of US military presence on the Caspian Sea. “America has no access to the sea, unless some of the neighbouring countries like Azerbaijan or Armenia or others collaborate [with them] … And they’re not collaborating on this because they don’t want to upset Russia,” Zweiri explained. “It will require … troops on the ground, and this is unlikely to happen.”
