Iran and the US
In a strategic chokepoint ...everything is compressed, everything is concentrated. It's about the geography. So even though the strait may be 20 miles wide, that doesn't mean to say there's 20 miles of manoeuvre space. There are lanes that go through, and islands to navigate around. There's traffic going in all directions. What does that mean? That the time to react to warnings is very short - and that becomes a problem.
