No one shot those Iranians rappelling down the rope from the chopper onto the deck of the oil tanker. Why not? After the first two soldiers would have hit the deck dead, that chopper would have skedaddled!
Surely anyone shipping through the Strait of Hormuz should have armed security on board. We should expect that from our feckless allies.
Shipping companies are notoriously cheap and effective security is expensive.
Arming tankers is not a good idea.
That might only provoke Iran into sending gunships ahead of the assault teams to suppress defensive fire, or respond to defensive fire by sinking the tanker by multiple means.
The solution is armed air assets patrolling the Straits 24/7.
Too bad Britain has little or none in the area. Perhaps they should spend more on navy ships/planes.
