NATO and International Security

I concur with what my right hon. Friend has said, but is it not the case that we now need to be making the case for deterrence, so that when Putin is providing maps and threats of nuclear destruction for western Europe, we can say very clearly what the response would be? It is that deterrent stance that has kept the peace since the second world war, and we need to keep reminding him, when he makes those threats, of the reason that we retain a nuclear deterrent.
