Defence and Security Review (NATO)

I apologise for coming in late. About 30 years ago, when Denis Healey, as Defence Secretary, looked down the road at the defence needs, he said that modern warfare for the future would rely more on conventional weapons than nuclear weapons and that sort of thing. On the hon. Gentleman’s other point, although we may not have planned for any war with Russia, I imagine the United States has, because it plays “war games”, for want of a better term, and examines various scenarios. What does he think about that? Does he know anything about that?
