Dr Julian Lewis: Does the Prime Minister agree that any idea that Europe could defend itself conventionally against an aggressive Russia is a dangerous fantasy if the United States is not involved?

[The Prime Minister: The United States obviously plays a very important role within the NATO alliance, but may I also remark – my right hon. Friend made the comment about defending conventionally against attacks from Russia – that, as we look at NATO for the future, we need to look not just at the conventional capabilities and the conventional threats. That is why I am proud that the United Kingdom was the first to put its offensive cyber-capability to the benefit of the alliance.]
