Iran's Islamic Revolutionary Guard Corps (IRGC) announced a new "offensive" defense doctrine on Wednesday, stating that Tehran would invade neighboring countries and strike U.S. military bases if the United States attacked again, Al Jazeera reported. An IRGC spokesperson said Iran's missile inventory has increased 1.5 times since the Iran-Israel War in June 2025 and that it is preparing to unveil a new "Father of all Bombs" weapon. Meanwhile, the U.S. has ordered some diplomatic staff to evacuate Saudi Arabia following media reports that the U.S. and Israel might launch attacks on Iran in the coming weeks.
