Perhaps it is close to the time when we realise 50 years of underfunding of infrastructure, health and education in the UK means our country is approaching third-world status with no money to do anything about it.
Perhaps then we might accept that a submarine-launched independent nuclear detterent is a luxury we simply can't afford and a simpler and cheaper option (land-based missiles like N Korea????) would free up billions of public money to mend the country and stop the Corbinistas from promising things we can't presently afford.
We don't have an Empire any more (the Commonwealth really doesn't count) and we are hardly a world-leader in economic terms so maybe it is time to scale things down - apart from our conventional forces which have been cut far too harshly.
