Apparently on taking office every Prime Minister of the United Kingdom is encouraged to handwrite a ‘Letter of Last Resort’, which is carried in every British ballistic missile submarine and is to be opened only in the event that governmental command authority has been destroyed.
According to the article four options are known to have been used:
retaliate with nuclear weapons;
do not retaliate with nuclear weapons;
uses their own judgement; or
place themself under United States or Australian command, if possible.
Leaving aside that the first option begs the question that the submarine commander needs to be aware of who to retaliate against I always thought the third option was fundementally cowardly, if not a dereliction of duty, you’re supposed to be the leader so make a decision and lead don’t place onto another persons conscience something you aren’t willing to accept yourself.
On discussing this with a friend he stated that he would order the sub commanders to make their way to Australia and, having jettisoned their nuclear warheads harmlessly somewhere along the way, place themselves under the command of the Royal Australian Navy, should that institution still exist.
I agree with that, deterrence only works if it deters, if the UK has suffered a first strike massive enough to remove all other command authority then those nuclear missiles have already been rendered meaningless and retaliation would only be an act of revenge on millions of innocent civilians from beyond the grave.
But as Prime Minister (stop laughing at the back) I’d make other nations leaderships believe that without a doubt I would launch a retaliatory strike even though secretly I actually wouldn’t.
So, for a laugh Bob the minorly godlike posthuman entity has shifted reality and you suddenly find yourself elected Prime Minister of the UK (much to your surprise I imagine) what do you put in your Letters of Last Resort?
