Op-For points out that thanks to Parliament, Britain is in no position to start a war with anyone, not even Iran, and even if they were it would be amazing if they’d go to war openly over the troop hostage taking. But why do it openly, asks Peter Boston, a commentor at the Belmont Club:
"Were I calling the shots for the Brits I would sink a patrolling Iranian submarine or two. Quietly and without pubilc announcement. Although we wouldn’t hear about it for another 50 years or so I imagine such an event would create a major confidence crisis in top Iranian circles and start destructive internal recriminations flying around."
Sounds like a winner to me. Better, certainly, than bringing in Jimmy Carter for advice. Hopefully, they’ll be released like the last group before some Iranian sailors lose their lives.

Not a bad idea. The Iranians aren’t very good at operating their subs anyway, so it might just be thought of as “an accident”
I think the point would be for them to realize what had happened without being able to do much about it, except play nice from then on. Or lose more.
A superb idea, but hard to believe that nowadays UK will do it. With Jimbo’s advice or withou. Ehehe…
