I'm only giving a neutral perspective. The moment the world stops relying on oil, Iran will lose its biggest leverage in this situation. Other sources of energy are going to be pushed even more.
There is more that goes through Hormuz than just oil- like fertilizer for example. Just been able to charge a fee for crossing the Hormuz is a strategic goal for Iran. This is an outcome of the war. Previously Iran did not know how weak US is - but now they figured out.
It would be interesting to see if this war will be a net negative for Israel. If Iran emerges with more financial resources out of the war you can bet they will fund Hamas and Hezbollah more than before the war.
From a distance, a railroad here would be great. Pay Ukraine to keep the drones away from it. I've been to the region, I understand that a sandy desert is a tough place to keep a rail line open though.
Yeah, I don't see it. Trump is also pathologically incapable of admitting defeat (see Jan 6) and it will be very difficult for him to claim victory without getting something better than the deal Obama got. There's little to no incentive for Iran to give him any such deal. Israel also doesn't want the war to end and they can easily sabotage any real negotiations that appear to be getting serious.
Trump has no off ramp. I don't see this ending until he is out of office.
