Excuse me, but this is a simplistic argument argument, a burglar is not deterred by "fake/dummy" burglar alarms on the outside of a house, nor will an alarm deter him if there is no possibility of arrest or punishment. A nuclear deterrent is just a very large and expensive bluff. There are other more insidious threats today-terrorism, biological warfare among them. I know that while we may consider the Cold War to be behind us, Russia today is a very dangerous threat -look at Ukraine and Crimea, but I still think to spend over £100 billion at a time when the rest of our armed forces amount to little more than a token presence or decorative tourist attraction, is a vanity which makes no sense. Aircraft carriers when we have no aircraft to carry? Massive redundancies in all 3 services? I may not know the perfect answer, but when our NHS is haemorrhaging money employing locus doctors and agency nurses because of staffing shortages, and we cannot afford care for the elderly, the demented or even open GP surgeries for one more day a week because of a shortage of GPs, well I think it is time we saw sense.
