Did you even read the post you replied to?

“what’s stopping you from quitting your work that you need to survive?”

This one? United Nations Convention on the Law of the Sea (UNCLOS)?

As far as I found out neither the US, nor Iran ratified this.

If you want to argue with law you need to have a law which all states involved follow.

That doesn’t apply here?

The strait of hormus does not lie in international waters. What do you mean by “high sea piracy”?
