Iran live updates: Trump says 'no chance' Iran war will last rest of his term

Iran claims that there will be a regional meeting with Gulf countries on Monday to discuss "the results of the negotiations between Iran and Oman regarding the establishment of safe routes for commercial shipping in the Strait of Hormuz," according to Iranian state TV, which cited Iranian Foreign Ministry spokesperson Esmaeil Baghaei.

There has been no confirmation yet from the GCC countries on what states will be attending but the gathering, if it happens, would be the first meeting between the top diplomats from the six-member Gulf Cooperation Council and a senior Iranian official since the U.S. and Israel launched the war against the Islamic republic in February.

During a speech at the Pentagon to mark the 25th anniversary of the 9/11 attacks, Trump brought up the war with Iran as he discussed America's response to global terror in the quarter century since the attacks.

"For 25 years our best and bravest have kept America safe and today we salute every member of the United States military who served in the war on terror. It is a war on sick, horrible terror," he said.

"We salute the service members working right now to ensure the world's number one sponsor of terror, the Islamic republic of Iran, will never ever have a nuclear weapon," he added.

Secretary of State Pete Hegseth said the U.S. is ensuring Iran "will never have a nuclear weapon," saying the U.S. controls the Strait of Hormuz and will finish the fight.

"The economic pressure tightens every day. We control the strait. We will finish this fight," Hegseth said during a 9/11 ceremony at the Pentagon on Friday.

"The United States has killed their leaders, destroyed their air force and their navy rests at the bottom of the sea," Hegseth said.

President Donald Trump dismissed reports Thursday night that his advisors have warned him the Iran war could last through the end of his term.

"No there's not even a chance of that," the president said.

The president's timeline has shifted repeatedly. He initially said the war would last four to six weeks.

The president was also asked about oil prices increasing as the war with Iran continues. Trump repeated his claims that prices will drop once the war ends.

“When that ends, I think it'll end very shortly after the election -- could end before the election -- but I think it'll end very shortly after the election, the prices will go down to less than $2 a barrel, $2 a gallon for oil,” he said.
