pdf27 I'd be fascinated to know exactly how you think the UK can extract 15 guys from what is apparently a Revolutionary Guards base somewhere in Tehran

Who said anything about rescue? As you pointed out a rescue mission is likely to be impractical and is likely to end up with more dead and more hostages.

Retaliatory strikes is what people said. It can be increased sanctions, and start any combination of the following; bombing, seizing assets, seizing vessels, ect.

What do you propose, send them flowers?

Just how is it bloodthirsty to want to try to prevent kidnappings, terrorism, war?

Sometimes you have to flight fire, with fire. If you can stop or prevent a forest fire with a few backfires (fire breaks) then why not?

Some action might get to the Iranians to release the kidnap soldiers, even if it does not achieve the release of the soldiers, the message might prevent oblivion.
