Supporters of nuclear weapons systems like Trident generally justify the cash by saying things like ‘dangerous world, Kim Jong Il and Ahmadinejad very bad men, we can’t just disarm’. Or, more cynically, ‘place on world table, we can’t just disarm’.
I’m not totally sold on this argument – after all, the US will continue to have nuclear weapons for as long as it has a military-industrial complex [*] – and anyone who we can’t defeat with our conventional forces is realistically also going to be a strategic threat to the Yanks, no matter how annoyed they might be with our lack of military spending. And ‘place on world table’ is awesome for a few hundred diplomats and politicians whilst making c.sod all difference to anyone else.
But let’s say it’s true: we need nuclear weapons to deal with global security threats and enhance our prestige. Fine – but I don’t think I’ve seen any coherent argument for why we need to spend £60-80bn on Trident, rather than achieving all the ‘potential for revenge’ and ‘woo, we’re a nucular state’ through a lower-tech programme like India’s – which would cost somewhere between 10% and 25% as much.
That would still give us ballistic and cruise missiles capable of obliterating anyone except for the US and Russia – who we wouldn’t be able to obliterate with Trident either, even if we wanted to (not least because most operational aspects of Trident are controlled by the US). Which ought to be enough, oughtn’t it?
Anything I’m missing…?
[*] which we don’t to quite the same extent.
