US Vice President JD Vance has found himself at the centre of the Trump administration’s efforts to secure a lasting peace agreement with Iran, a role that has become increasingly politically risky as negotiations face mounting criticism and uncertainty. With US President Donald Trump publicly suggesting on more than one occasion that Vance would be held responsible if the talks failed, the vice president has effectively become the public face of a negotiation process that many critics believe is not progressing in Washington’s favour.
Vance’s central role was highlighted during talks in Geneva on Sunday when the Iranian delegation, led by chief negotiator Mohammad Baqer Qalibaf and Foreign Minister Abbas Araqchi, walked out of a scheduled photo opportunity with American officials. The move, reportedly prompted by fresh comments from Trump and disagreements over diplomatic optics, attracted significant attention and left Vance facing immediate criticism as the most visible representative of the US side.
The controversy surrounding the negotiations has been intensified by opposition to Trump’s proposed 14-point peace framework. Critics, particularly among Republican national security conservatives, argue that the agreement grants excessive concessions to Iran, including the easing of oil sanctions and the release of frozen Iranian assets. As criticism has grown, Vance has become one of the administration’s strongest public defenders of the deal despite previously being known as a sceptic of American involvement in Middle Eastern conflicts.
While senior administration figures such as Secretary of State Marco Rubio and Secretary of War Pete Hegseth have remained relatively less visible in defending the negotiations, Vance has taken on a leading role. His political future has consequently become closely linked to the outcome of the talks. A successful agreement could significantly strengthen his standing within the Republican Party and boost his prospects as a future presidential contender. However, a collapse of the negotiations could leave him carrying much of the political blame.
The framework itself has sparked intense opposition among Republican lawmakers. Several prominent figures have argued that the agreement fails to adequately address Iran’s strategic ambitions. Critics have expressed concern over provisions related to sanctions relief, financial concessions and reconstruction assistance, arguing that the proposed measures represent a substantial departure from the administration’s earlier hardline stance toward Tehran.
Media criticism has also intensified, with some conservative commentators and publications describing the framework as overly favourable to Iran. Despite the backlash, Trump has appeared relatively unconcerned publicly. During a June 17 interaction with reporters, he jokingly remarked that he would claim credit if the agreement succeeded but would blame Vance if it failed, a comment that many observers interpreted as a clear political signal regarding responsibility for the negotiations.
What makes the situation particularly notable is that Vance had previously been among the administration’s strongest voices against deeper involvement in conflicts in the Middle East. Nevertheless, he has now become the principal advocate for the Iran talks. The White House further reinforced his association with the negotiations by publicly describing him as one of the key figures leading discussions alongside Special Envoy Steve Witkoff and Jared Kushner.
In recent weeks, Vance has actively defended the framework, responding to criticism from fellow Republicans and rejecting claims that the United States is surrendering leverage. He has argued that sanctions relief and diplomatic engagement would ultimately benefit American interests and insisted that the agreement does not represent a financial giveaway to Iran.
As debate over the negotiations continues, some conservative commentators have increasingly referred to the framework as “Vance’s deal,” placing responsibility for its success or failure squarely on the vice president rather than on Trump. Political analysts have suggested that this dynamic allows the president to remain somewhat insulated from criticism should the negotiations collapse.
Within Republican circles, the perception that Vance has become the chief architect and defender of the agreement has continued to grow. Critics have framed the issue not as a failure of Trump’s strategy but as a challenge for Vance personally. Political observers note that Trump’s decision to allow his vice president to take such a visible role may have been deliberate, creating a situation in which Vance receives either the credit for a diplomatic breakthrough or the blame for an unsuccessful outcome.
As negotiations with Iran continue amid uncertainty, Vance’s political fortunes appear increasingly tied to their outcome. If a durable agreement is reached, he could emerge as a leading figure in Republican foreign policy and strengthen his standing ahead of future national campaigns. If the talks break down, however, the responsibility for what critics describe as an embarrassing diplomatic setback may fall heavily on him. As one political insider reportedly observed, the vice president will receive the credit for the negotiations’ outcome—whether that ultimately proves beneficial or damaging remains to be seen.
