It's already happening. Iran now charges a toll for passage through Hormuz. Iran has destroyed US bases across the region and pushed back the empire. They are already in a far stronger position than they were before the war started. All the Gulf states can now see that the US security umbrella is worthless, and they have to start making deals with Iran if they are to survive. The defeat of the fascists by Iran in their region is absolutely going to make Iran stronger going forward.
