Strategic Defence and Security Review

I agree with the hon. Gentleman, and we do not need to go that far back. When I was growing up in the 1970s—I know it does not seem possible, but I am genuinely that old—we were facing what we were sure was the actual threat, which was the Soviet Union pouring across the plains of Germany, massed tank battles and the use of tactical nuclear weapons, and then no doubt some form of nuclear holocaust engulfing the world. Nobody mentioned North Korea or Iran—they were not even on the radar. It is clearly difficult to guess what the future holds.
