US Vice President JD Vance has warned Iran amid continued uncertainty, accusing Tehran of making commitments that it sometimes fails to honour.

In an interview with Fox News, Vance said he was confident the situation would eventually leave the United States in a stronger position. He said Iran would not have nuclear weapons and conditions in the Strait of Hormuz would return to normal.

Vance said Washington also wants oil and gas prices to remain stable and affordable for American consumers. He described preventing Iran from obtaining nuclear weapons and maintaining energy price stability as two key US objectives.

“Sometimes the Iranians make promises that they don’t keep,” Vance said, arguing that Tehran has entered into agreements in the past but failed to implement them.

Asked why the US approach toward Iran has appeared to fluctuate, Vance said Washington has several tools available to achieve its goals. He explained that the US sometimes focuses on energy issues, while at other times it concentrates on military measures or Iran’s nuclear programme.

Vance said the administration is using its resources carefully and strategically to achieve the outcomes sought by President Donald Trump for the American people.

He stressed that the US strategy is not limited to one area, but involves economic, energy, military and diplomatic considerations.

The vice president expressed confidence that Washington was making progress toward its objectives, particularly preventing Iran from acquiring nuclear weapons and keeping oil and gas prices stable.

His remarks come as tensions surrounding Iran continue to raise concerns about regional security, energy markets and the future of the Strait of Hormuz, a major route for global oil and gas shipments.
