The US navy escorted ships through the strait back in the Iran Iraq war, but the situation has changed. There are naval drones and aerial drones now, the Iranians have access to Russian satellite data, and the US doesn’t have the volume and mix of ship types it had back then. The US navy has been over optimised for deep water peer fleet conflict. Bear in mind, the Red Sea has been functionally closed by the Houthis for years now.

Yeah exactly. Drones have changed everything. What might have used to be routine is now no longer the case. Iran just has to project power in the media, and shoot some drones out at some boats every now and then and they effectively “control“ the straight. The shipping insurance markets skyrocketed as a result, so ships literally couldn’t afford to take the risk and stayed put.
