Iranian President Masoud Pezeshkian has issued a stark warning to President Donald Trump, saying any U.S. military strike on Iran would trigger a harsh and regrettable response, amounting to all-out war. Pezeshkian also warned that any attack targeting Iran’s Supreme Leader would be treated as an attack on the entire nation. The warning comes after Trump suggested it may be time for new leadership in Iran, amid widespread protests and mounting international pressure. Iranian officials say such statements are dangerous and could push the region toward direct conflict.
