Britain should spend less on defence. It is a waste of money and should be reduced so more could be spent on supporting employment, welfare and growth. Why is there no such debate? Why should “defence” be awarded an almost religious invulnerability? At present, parliament, broadcasters, print and social media, thinktanks and pundits all admit to only two points of view. One is that Britain should spend more on defence, the other is that it should spend far more.
