You are missing the point actually. We are talking about a world where might is right. That's the world US is making with our flagrant violation of international law.
WHY should the laws be applied selectively? If Iran has ballistic missile capability to enforce its toll in Omani waters then they can and should do so. Might makes right, right? If America/Israel can just decide to bomb a foreign nation, kill its leader, the leaders family, bomb school children, in comparison Iran controlling the strait and asking for tolls seems benign.
Or are you a racist who doesn't see Iranians as human beings?
