Defence and Security Review (NATO)

I thank the hon. Gentleman for giving way. The Defence Committee, which completed its report on deterrence just before he assumed the Chair, made it clear that in the event of a cyber attack we should be prepared to say to a potential adversary such as Russia, “We will not necessarily wait for 100% proof before we enact counter-measures.” We should do that despite the fact that it might have tried to create some uncertainty and ambiguity over the exact emanation of such an attack.
