You see? Now you are already making the world your enemy by what you saying. Don't use the word coercon. That just makes iran's use of the strait of hormuz less legitimate. The strait of Hormuz cannot be used as a threat, only an equalizer against US attack. The moment it is proactively used as a threat, it becomes something the world cannot tolerate, and thus a coalition against it may be formed.
Iran cannot threaten to block strait of Hormus however it sees fit. They must have a just cause. Otherwise they are nothing more than pirates, and a coalition may gradually form. That is the worst case scenario, and must be avoided. The Hardliners have done their part already, it is time for negotiations, and I am afraid this is Irans weak suit.
