Cost of replacing Trident: £26bn.
Cost of ALL secondary and university education in the UK: £27bn.
Trident is a fucking stupid, expensive bit of posturing which we’ll never use. Can you imagine ANY scenario in which we’d actually use it? Or ANY scenario in which someone would choose not to do something on account of our having it? So why don’t we just build a fake one instead? If it works for police cars on bridges, I’ll bet it would work for nuclear submarines.
