Iran live updates: Iran has 'thousands' of missiles and drones left

Sen. Lindsey Graham, R-S.C., said he spoke with President Donald Trump and Secretary of Defense Pete Hegseth Wednesday morning about the “way forward” in Iran.

Graham said that he expects the blockade of Iranian ports to stay in place and even expand, saying "it could become global soon” unless Iran “shows a commitment to change their ways."

Graham was not clear about where this blockade would expand and what the U.S. is specifically asking the Iranians to commit to in terms of "changing their ways."

"I had a very good call this morning with @POTUS and @SecWar Pete Hegseth about the way forward regarding the Iran conflict," Graham said in a post on X Wednesday.

"I not only expect this blockade to stay in place until Iran shows a commitment to change their ways, I expect the blockade will be growing and that it could become global soon,” he said.

Graham also issued a warning to other countries amid threats of a global blockade, saying that any nation "assisting or thinking about assisting the Iranian regime in distributing its oil," will do so "at your own peril."

President Donald Trump said that a renewed round of peace talks in the next 36 to 72 hours is "possible" in a text exchange with the New York Post Wednesday morning. The Post article cited sources saying that a new round of talks is possible as soon as Friday.

"It’s possible! President DJT," Trump said in a text message when asked about the possibility of those talks, according to the New York Post.

Iranian Foreign Ministry spokesperson Esmaeil Baghaei said Wednesday that the U.S.-Israeli war was imposed on Tehran and that all subsequent Iranian actions have been "in line with Iran's inherent right to legitimate defense against the military aggression," as quoted by Iranian state television.

Regarding Iran's non-attendance of a second round of peace talks in Islamabad this week, Baghaei said, "Diplomacy is a tool for securing national interests and security," adding that Iran will act only when it reaches the conclusion that "the necessary and logical grounds for using this tool to realize national interests" have been established.

Iran, Baghaei said, "will use every opportunity and capacity to hold the aggressors accountable and to realize Iran's rights, including administering justice to the perpetrators and founders of war crimes and demanding compensation."

The Islamic Revolutionary Guard Corps Navy confirmed its interdiction and seizure of two vessels on Wednesday which it said were "attempting to secretly exit the Strait of Hormuz."

The IRGC Navy named the two vessels as the MSC Francesca and the Epaminondas. Both were transferred to Iranian territorial waters "in order to examine the cargo and documents," the navy said.

ABC News has reached out to MSC for comment.
