I think the Iranians know enough about him now to know that even though he may withdraw, it won't be shamefaced and defeated. THEY will have to be the ones to attribute such attributes to his withdrawal/defeat. Some in the American media will amplify their claims as shipping through the strait returns to normal.
Some of the biggest losers in this will be the oil producers in the Middle East; the Saudi's especially. With Iran and Oman collecting tolls, Middle Eastern oil will become more expensive; especially compared to the Venezuelan oil expected to come online in a few years. Also, the frailty of the Middle Eastern oil supply is going to give a nudge to renewables and encourage the development of alternate sources. Either way, the world is done with dealing with the uncertainly of the oil supply emanating out of the Middle East.
Poll: Trump Has Prioritized His Personal Business Interests
And he is going to do EVERYTHING possible to protect those interests. Those interests will become threatened when/if Democrats take control of either either house of Congress. He is going to do EVERYTHING (legal and illegal) possible to prevent that from happening. Illegal immigration will be the rubric for all of his shenanigans. It started with illegals receiving mail in ballots. That failed so next it will be chaos at the polls to prevent illegals from voting followed by the seizures of ballots because illegals voted so that the vote can't be certified at the county level. Finally it will be failure to certify the vote at the federal level! All along the way, he has the hope that there will be massive demonstrations which he will declare to be violent so that he can call out the National Guard and declare Martial Law.
This will be a rough election! If he takes those actions and Democrats STILL prevail, the FIRST thing they must do is impeach and convict his butt while passions are still red hot.
