"Iran's Revolutionary Guards have issued a sharp warning, vowing a "devastating and decisive response" if Israel initiates any military action against Iranian nuclear facilities. The statement, delivered through state media, came after reports that U.S. intelligence believes Israel may be preparing for a potential strike on Iranian nuclear sites."
Iran doesn't have the juice to last 48 hours in a war with Israel...with no US help. But, of course, they WILL have US help because we want to participate in the monkey plinkery.
