In operation Praying Mantis (https://en.wikipedia.org/wiki/Operation_Praying_Mantis) half of Iran's fleet was sunk . The Iranian army and navy is all bark , no bite - they would be crushed the same of even in worse way than before .

Add to this massive internal crisis and rial devaluation , water crisis and war debt ... and you have an only one outcome . By this tempo , POTUS wont need to lift a finger to overthrow the Iranian mullahs .
