Commons ChamberI am afraid that the hon. Gentleman does not make a coherent case. Chemical weapons have certainly been used in recent times—we do not know whether biological weapons have been used—which means that nuclear weapons did not act as a deterrent, so his argument is not sound.
The right hon. Lady makes a necessary contribution to this debate and she asks a very interesting question about the banning of other unacceptable weapons systems while we continue to possess nuclear weapons. But is it not the case that nuclear weapons represent, in the psychology of our global civilisation, an unacceptable threshold of use? Therefore, they have a deterrent effect because the release of one weapon could release many. I ask her this question: why, since the end of the second world war when nuclear weapons were first deployed, did war between the great powers end? Why was that the last world war? Could the possession of nuclear weapons have something to do with it?
I am afraid that the hon. Gentleman does not know his history. There have been hundreds of wars since that time and hundreds of thousands of people have died. Many of the wars were proxy wars between the superpowers, so his argument is completely invalid. If he argues that deterrence is so wonderful because the weapons are never used, then he has to ask: why have them at all? Let us get rid of them rather than posture and spend vast fortunes and create a situation in which, at the very least, accidents and misjudgments could happen. The point about luck is that eventually it runs out, and that could happen.
It is instructive to inquire how other countries and institutions view the nuclear weapon states. I had an opportunity to find that out last December when I attended a conference organised by the Austrian Government on the humanitarian effects of the use of nuclear weapons, to which the hon. Member for Moray (Angus Robertson) has already referred. Building on two previous meetings hosted by Norway and Mexico, this conference was attended by representatives of no fewer than 157 Governments. Most telling were the contributions of the International Red Cross and Red Crescent, the bodies on which the whole world depends, regardless of politics, in cases of natural disaster. Let me quote from their statement:
“Even though only a few states currently possess nuclear weapons, they are a concern to all states…They can only bring us to a catastrophic and irreversible scenario that no one wishes and to which no one can respond in any meaningful way.”
Their statement continues:
“All other weapons of mass destruction, namely chemical and biological weapons, have been banned. Nuclear weapons—which have far worse consequences than those weapons—must now be specifically prohibited and eliminated as a matter of urgency.”
I do not think that there is anyone who could not respect a statement from the Red Cross and the Red Crescent.
