If the US are not going to launch a ground invasion to remove the regime then the US and Israel should target and destroy all regime oil infrastructure. No Iranian oil should be able to leave port again. If the regime is stopping everyone else shipping oil they should certainly not be able to ship their own oil. Also a total air and sea blockade of Iran. Are Iranian ports and airports still open? How about destroying the runways all port facilities. Are the US and Israel actually in this to win or just wasting time?!
