People honestly forget that Iranians aren't stupid. Some of them are crazy, but not stupid. Iran has been doing things like saying you're safe in the Strait as long as you trade oil in Yuan, for example. They know exactly why they're doing that.

Now it's not very effective now, but if the US packs up and leaves they can keep doing it. "Trade in Yuan or we drone strike your ships" would lead to every company that operates there doing it provided it actually kept risk and insurance rates down.
