At a minimum, countries will be seeking to get their oil and goods from other sources (The US and others) as the war made it very clear that the Iranian Regime thinks the Strait of Hormuz is THEIRS to mine, charge tolls, or bomb tankers. Secondly we proved in battle conditions that Chinese air defense systems which was in effect "protecting Iran" were powerless against our air attacks. We also found a big hole in our defenses that being weaponized drones. We are quickly filling that void both offensively and defensively.
President Trump also said today than the signing of the MOU is NOT the end all and if he doesn't like the final agreement he has no problem dropping bombs on their heads. IMHO that is what needs to happen.
