Re: Let's start a nuclear ware in a spiteful tantrum
So what would your solution be to the situation whereby the UK was threatened with being attacked by biological attack?
We're currently living through the effects of Covid - a relatively minor disease (relatively - compared to what might be used as a biological warfare agent). We have a death-with-covid figure well north of 100,000 (ok, all sorts of issues with that figure, but including those that died because of covid and those that died or will die because of the response to covid, the order of magnitude is probably about right). It's devastated the economy.
And that's a non-targeted 'attack' (no, I don't consider it an intentional act) using a minor disease.
The UK's nukes are referred to as the nuclear deterrent. That doesn't (just) mean a deterrent to other people's nukes, it means they are nukes, and they are owned by the UK to function as a deterrent.
They are also proportional - there is no expectation that they would deter terrorist attack or the Argentinian invasion of the Falklands, because there would be no valid target / they would be disproportionate. No one would believe the UK would use them in such a case, so they would not deter.
They deter strategic level attack. Originally: Nuclear, biological, chemical. Radiological crept into that list some years ago. As societies become more reliant on integrated IT throughout every aspect of life, there is a move to viewing 'cyber attacks' also as attacks by weapons of mass destruction. The quote says it itself "devastating cyber attack". Britain is a relatively warm place really, compared to some, but if the national grid was knocked off line for a week in the middle of winter, that could easily be tens of thousands of dead.
The UK's policy is to deter strategic attacks (inevitably meaning by state level actors) using the threat of nuclear retaliation.
It doesn't matter if the threat of attack is nuclear weapons, chemical weapons, biological weapons or radiological 'dirty bombs', the UK response is that if you hit the UK with a mass-destruction attack, we have the capability and the will to respond on an equally devastating level.
So no, you are absolutely wrong.
When faced by threats, de-escalate, Talk, try to compromise, try to find a peaceful solution.
But retain the capability to defend yourself, and make it clear to any potential aggressor that they cannot attack you without consequences.
