I don't know why we bother with nuclear, if it goes tits we're fu@&£d either way, probably improve the country and our future prospects if London was flattened (assuming it was a weekday and parliament wasn't in recess).
Best just spending the budget on conventional weapons, so we can continue to invade oil rich states for BS reasons and pretend we're a big player with half a dozen JSFs on a floating tin pot, I mean can.
