Firstly, there's no evidence that the Soviets had any intention of invading Europe in the 60s
Evidence like a couple of 'Armoured Guards' and 'Shock' Armies posted to East Germany?
It's arguable that the possession of nuclear weapons will not stop an aggressor - did it stop Argentina invading the Falklands?
Argentina didn't think we'd fight for the Falklands. We're talking about a deterrent to trying to nuke us, not a deterrent to trying to steal a couple of islands and several thousand sheep in the south Atlantic
If we are talking about having them to stop a rogue 'lunatic' dictator - again, it won't work. The very fact that these people are unstable means that we can't rely on logic to sstop them.
We can rely on the fact that they want to live to stop them. Since even we have enough nuclear firepower to turn most of the world into a skating rink, I doubt there's very many people in this world who would consider a non-conventional attack on the UK a good idea.
The main security threat to 'The West' is terrorism and having a nuclear 'deterrent' won't help there.
And having anti terror police won't stop a nuclear attack. The main threat to Britain in the 1930s was tribesmen in the colonies - thank fuck someone thought that we might just end up in another war eh?
I was a member of CND in the 80s and didn't believe in having Trident then - with the fall of the Soviet Union, there is much less justification in spending these huge amounts of money on Trident.
Huge amounts? Even at the top end of the scale claimed here (I've never seen the £70 billion figure before), it's less over 30 years than the NHS or Welfare costs us EVERY year.
If necessary, we should be spending some of the money on strengthening our defence against the threat of terrorism, which, to my mind is a far greater danger than the unlikely event of a nuclear attack on the UK.
How many anti-terror police will we need in fifteen years when we get into an argument with a new hard line dictatorship in Russia and they turn us into a glass sculpture without fear of reprisal?
And I wouldn't want anyone else doing that. Just hope you all have the equipment required should you be needed.
So do we...
