A large scale war is not on the cards nor politically, economically or militarily feasible and that is why he wants to set a new normal. Choke Iran for internal chaos, intermittent bombings under a threshold that do not transcend into a precipitous conflict. Zion has learned a thing or two as well... that it is a military midget without US even WITH all of US and the collective military umbrella, support, supply and technology.
It is up to Iran now to find an out... because the US doesn't care if the world starves or collapses economically as long as the US itself is not directly impacted... the price US is willing to pay the wellbeing of the rest of the world. That is the zero sum mindset where US would want to rule the ruins but not allow prosperity skipping it...
The euroasian overland bilateral or multilateral trade will totally omit any western or collective input after centuries of sabotage and subterfuge.
