Mohsen Rezaei, an adviser to Iran's leader Mojtaba Khamenei, told PressTV that Tehran is considering whether to end its ban on nuclear weapons, though he said no decision has been made. He also said the "tone" of the Americans had changed after a letter from US Vice President JD Vance. A public debate in Tehran over crossing the nuclear threshold would raise the stakes of any renewed confrontation with Israel and the United States, though the statement is a signal, not a policy change.
