Vance reassigned to domestic investigations as Trump seeks to move on from the Iran war

Vice President J.D. Vance was the Trump administration’s principal advocate of a negotiated end to the Iran war. He has now been asked to focus on alleged crime and corruption in Democratic-run cities and states. Donald Trump has directed the vice president to give the issue his “complete and total attention”, cancelling his planned trips to South America and the Caribbean.

The timing is significant. Vance had led the US delegation at talks with Iranian officials in Islamabad. More recently, he sent a letter through Qatari mediators to Mohsen Rezaei, Iran’s security chief, exploring the possibility of renewed negotiations. Trump subsequently said the United States no longer needed a deal with Tehran.

The reassignment takes Vance away from the diplomatic effort at a time when the conflict remains unresolved. It also places him at the centre of the administration’s domestic political response to the midterm elections.

The political context is important. Republicans lost control of both chambers of Congress in the November 3 midterms. Vance attributed the setback partly to the Iran war and its economic consequences, particularly rising fuel prices.

A Reuters/Ipsos poll found that 71 per cent of Americans, including 51 per cent of Republicans, supported congressional legislation to end the war. The economic impact of the conflict has added to the cost-of-living concerns that affected Republican prospects.

Trump has acknowledged the impact of fuel prices but has sought to shift the political debate towards crime and corruption. Democrats, meanwhile, are preparing investigations into his administration and business dealings when the new Congress convenes in January. Vance’s new assignment gives the White House an opportunity to counter those efforts.

Trump has presented the conflict as a military success, arguing that Washington no longer needs a diplomatic agreement. In a social media post, he claimed that the United States had secured control over Iranian funds worth hundreds of billions of dollars and the Strait of Hormuz.

The position contrasts with the original justification for the war. The strikes were intended to neutralise Iran’s nuclear capabilities. Eight months later, there is no new nuclear agreement and the conflict has not produced a durable settlement.

Washington continues to maintain its naval blockade and economic pressure on Tehran. But declaring the military campaign over does not resolve the underlying nuclear and security disputes. The administration has yet to outline how it intends to secure a lasting settlement.

The conflict has exposed differences within the administration over the way forward. Vance favoured negotiations, while Secretary of State Marco Rubio, CIA Director John Ratcliffe, Treasury Secretary Scott Bessent and Jared Kushner have supported maintaining pressure on Tehran. The administration’s argument is that economic restrictions and the naval blockade can force Iran into concessions without the need for another major military campaign. Hardliners also believe sustained economic pressure could weaken the Iranian leadership.

Trump has opted for a combination of economic coercion and military containment. The naval blockade of Iranian ports and the newly announced Task Force Iron Gate, intended to disrupt overland supply routes, are part of this strategy. It allows Washington to maintain pressure while avoiding the immediate costs of renewed strikes. Vance’s preference for a negotiated settlement has consequently lost influence, although the administration’s pressure strategy has yet to produce an agreement.

The security situation in the Gulf remains uncertain. Commercial shipping continues to face risks from attacks and disruptions around the Strait of Hormuz. The United Kingdom Maritime Trade Operations Centre has reported incidents involving commercial vessels, including explosions and projectile strikes. While Iran is unable to export its oil because of the American blockade, it still retains the capability to threaten the shipping channels. It can use missiles and drones to target regional energy supplies.

Unsurprisingly, Brent crude rose on November 12 amid renewed concerns about supply disruptions and the security of shipping routes. The continuing uncertainty illustrates the limitations of Washington’s strategy: economic pressure on Iran has not translated into stability in the Gulf.

Iran has rejected Washington’s claims of victory. Foreign Minister Abbas Araghchi and Rezaei have dismissed the American position, insisting that Tehran will not accept a settlement imposed through threats and a unilateral blockade. Iran wants sanctions lifted and its frozen assets released as part of a broader settlement. It has also resisted Washington’s demand for concessions on its nuclear programme.

The continuing confrontation leaves both sides with limited room for manoeuvre. The blockade could intensify pressure on Iran’s economy, but it also increases the possibility of retaliation against US forces and regional shipping. Gulf countries remain exposed to the consequences of any escalation.
