Yesterday, the former First Sea Lord, Admiral Sir Alan West, said British rules of engagement were "very much de-escalatory, because we don't want wars starting ... Rather than roaring into action and sinking everything in sight we try to step back and that, of course, is why our chaps were, in effect, able to be captured and taken away."

Our boarding team's training is a little bit more towards self-preservation." The unique US Navy rules of engagement say we not only have a right to self-defence but also an obligation to self-defence. They [the British] had every right in my mind and every justification to defend themselves rather than allow themselves to be taken. Our reaction was, 'Why didn't your guys defend themselves?'"
