Well we could have nuked them twice, back when the Vulcan was our way of delivering a nuclear warhead, the RAF were involved in a joint exercise to test the air defenses of the US, they were highly embarrassed that one Vulcan managed to get through and could have dropped a nuclear bomb, so after lots of work, planning and testing they were confident it wouldn’t happen again, at the next exercise along came the Vulcans and guess what, one got through the new improved defenses, the US were so shown up they buried the facts about what happened wherever such things get sent to gather cobwebs and never mentioned it again
