BBC Newshour: Iran and Reopening the Strait of Hormuz

It's a narrow strait, it's only 20 miles across at its narrowest point. On the Iranian side, there are mountains and islands. It's pretty easy for the Iranians to hide weapon systems, hide sensors, move them around and to hide behind islands and in valleys and so on. So it's much easier for them to attack shipping than it is for a coalition or a single country to protect it. And so I think what we're talking about...if the fight is still ongoing, is that the Strait of Hormuz is a kill zone and it's going to be pretty difficult to protect shipping going through that."
