I pity Iran if tried to close Hormoz strait...It's just an invitation to go all the way with the war and annihilate anything and everything adjacent to the Arab Gulf on the Iranian side.
I don't the point of closing the Strait of homoz Idea! What will they acheive? The minesweppers will come and go along with Maritime Survellience Aircrafts. They US would have a justification to intervene. They should just conserve their mikitary force for an couter attack on Isreal rather than comminting millitary and political sucide.
