US Vice President JD Vance has said Washington is prepared to use every available tool, including diplomatic, economic and military measures, to address the ongoing conflict with Iran, while continuing efforts to find a negotiated solution.

Speaking in an interview with Fox News, Vance described talks with Tehran as highly challenging, citing both the complexity of the negotiations and divisions within Iran's leadership.

According to the vice president, one of the biggest obstacles is that Iranian negotiators are difficult counterparts, making progress at the negotiating table slow and uncertain. He added that internal political divisions in Iran have further complicated efforts to reach an agreement.

Vance said there are factions within Iran that favour bringing the conflict to an end, while hardline elements continue to support maintaining tensions. He argued that these competing positions have made it harder for both sides to achieve meaningful progress.

Despite the challenges, the US remains committed to pursuing diplomacy while keeping other options available if necessary. Vance said Washington's approach is aimed at protecting its national security interests and maintaining stability in the Middle East.

His remarks came a day after President Donald Trump announced that a planned military strike against Iran had been postponed, saying negotiations with Tehran were still ongoing. Trump expressed hope that diplomatic engagement could produce a positive outcome, though he did not rule out further action if talks fail.

The latest comments from senior US officials suggest that the administration continues to prioritise diplomacy but remains prepared to take additional steps depending on how negotiations develop.
