President Donald Trump issued new warnings toward Iran on Sunday as Vice President JD Vance joined high-level U.S.-Iran talks in Switzerland. The meetings are aimed at preserving a fragile deal and addressing Iran’s nuclear program, the Strait of Hormuz and fighting in Lebanon.
U.S.-Iran Talks Open Under Heavy Pressure
The talks began at the Bürgenstock resort near Lake Lucerne, according to the Associated Press. Vance led the U.S. team, while Iranian officials included Foreign Minister Abbas Araghchi and parliamentary Speaker Mohammad Bagher Qalibaf.
Pakistani and Qatari officials also took part as mediators. Both countries have helped keep communication open between Washington and Tehran during the conflict.
The meeting marked a rare direct encounter between senior U.S. and Iranian officials. Most recent negotiations have taken place through intermediaries.
CBS News reported that Vance and Iranian officials briefly appeared in the same room during the opening session. The outlet said U.S. and Iranian officials did not appear to interact during the short media access period.
Trump Issues New Warnings Over Iran
While Vance pushed diplomacy, Trump delivered a sharply different message from Washington.
CBS News reported that Trump warned Iran against closing the Strait of Hormuz, a major global oil shipping route. He also threatened renewed U.S. military action if Iran did not stop Hezbollah from “causing trouble” in Lebanon.
Trump’s comments came as negotiators worked on details of a 60-day framework. The deal is intended to reduce fighting and create space for a longer-term agreement.
The Strait of Hormuz remains a central issue. Iran said it would close the waterway, citing continued fighting between Israel and Hezbollah. The U.S. has disputed Iran’s control over the strait and says the route remains open.
Any extended disruption could affect energy markets. Millions of barrels of oil pass through the waterway each day.
Vance Says Diplomacy Can Still Move Forward
Vance said the United States wants progress on several fronts. Those include Iran’s nuclear program and a ceasefire related to Lebanon.
According to CBS News, Vance said “great progress” had been made in recent days. He also said Trump had committed the U.S. to pursuing a wider regional ceasefire.
The Guardian reported that Lebanon was added to the agenda after Iran pressed for fighting there to stop. Israel and Hezbollah have continued to trade accusations over ceasefire violations.
Iran has argued that continued Israeli military action in Lebanon undermines the broader agreement. Israel has said it is not bound by the U.S.-Iran ceasefire arrangement.
Nuclear Program Remains Major Obstacle
Iran’s nuclear program remains one of the biggest barriers to a final agreement. The Trump administration wants Iran to abandon uranium enrichment.
Iran has rejected that demand. Tehran says its nuclear work is for peaceful purposes.
Western governments have long raised concerns about Iran’s enrichment levels. Higher enrichment can shorten the time needed to produce weapons-grade material, although Iran denies seeking nuclear weapons.
The Switzerland talks are expected to continue with technical teams, even if Vance leaves after a short stay.
For families watching from Texas and across the country, the stakes remain clear. The outcome could affect global security, energy prices and the chance of avoiding a wider war.
