I agree with my hon. Friend's first point. It is very important that in an Alliance of equal, free, democratic nations all should pull their weight in the common defence. We certainly want to make sure that we play our full part and that we encourage all our allies to do the same.
Not only has the policy of deterrence been inordinately successful over many years now, but it is pointless to have a deterrent that one says in advance one is not prepared to use. The Government's policy is clear: the best way of preventing all war is nuclear deterrence.
