I just got my tax statement for the last tax year, on the back it says how much of the tax I paid went to different areas of government spending, welfare was top, then health I think, defence was some way down the list and shamefully a similar value to government debt interest payments, EU membership was bottom of the list and less than foreign aid.
The whole point of Trident and any nuclear deterrent is that you hope never to
FIRE it, but you are
USING it 24x7 as a deterrent. Without Trident it is likely that defence spending would be the same anyway to compensate with a more powerful conventional force but that still leaves you ultimately at the mercy of a nuclear armed enemy. Whilst our
current major security threat is terrorists and guerillas who knows what might happen in 20 years, Russia might be back in cold war stance or another country might acquire nuclear weapons - Argentina for example. The US or NATO didn't help us at all last time Argentina got a bit fighty and it was French built Exocet missiles that did so much damage to our ships - we need an independent deterrent because we can't rely on our supposed "allies" to help and/or not inadvertently arm our enemies.
Luckily we could handle Argentina without resorting to nuking them but that doesn't mean we'll always be able to do that for every enemy and it's too late to build a Trident submarine once you realise you need it, you just have to retain them and in so doing pretty much ensure no country will launch a serious attack because even if they start winning over our conventional forces we can just flatten major cities in their home nation until they stop. Nuclear weapons ended WW2 earlier and with a lower total loss of life than a conventional invasion of Japan would likely have caused, they are awful weapons but humanity can be just as destructive over time without them. It is likely that nuclear weapons prevented the cold war developing into WW3 because nobody dared to start it; Trident is expensive but it is a lot cheaper than a large scale shooting war with a powerful enemy.
