I absolutely agree with the point about deterrence, and I have been making it in various debates. The noble Baroness, Lady Goldie, has been present at those debates, and the noble Lord, Lord Dannatt, asked me about this during the previous Urgent Question we had on defence. We need to re-establish deterrence. We need people to know that there are lines which, if crossed, will result in consequences. Perhaps we have not given the priority to deterrence that we should have, but the noble Earl is right that it must play an appropriate part in future. Countries know that, with our allies, we stand up for certain things and that if those lines are crossed, there will be consequences.
