US-UK Mutual Defence Agreement

Debate between John Leech and Julian Lewis

Thursday 6th November 2014 Westminster Hall

[Dr Julian Lewis (New Forest East) (Con)]

It is a pleasure to contribute to the debate under your chairmanship, Sir Roger, and a pleasure, as always, to follow the eloquent case made by the hon. Member for Islington North (Jeremy Corbyn). I am always happy to support him when he applies for debates such as this, just as he is always happy to support me when I apply for debates about nuclear deterrence. The reason why we are happy to support each other, despite taking entirely opposite views, is that we both feel that we have a good case to make.

There is no earthly reason why Parliament should be shy of debating such an important matter. The hon. Gentleman may find it a trifle more disappointing than I do that if we took a trip down memory lane to a similar debate in the 1980s, the Chamber would be full of people wishing to contribute. He and I have, to put it mildly, struggled a little to get people to come along and take part in this debate, for the simple reason that the issue is not nearly as contentious now as it was two or three decades ago.

I venture to suggest that that is because the British public have spoken on the matter, over and over again. They spoke decisively on it in the general elections of 1983 and 1987, when the question of Britain one-sidedly abandoning its nuclear deterrent was central to campaigning. They have spoken time and again in public opinion polls. Of course, it is possible to vary the answers that we receive in such polls according to the questions we ask. However, when we ask what I regard as the fundamental question: “Do you think that Britain should continue to possess a nuclear deterrent or nuclear weapons while other countries have them?”, invariably, about two thirds of the respondents say yes, about a quarter say no and a small, single-figure fraction are undecided. The issue is divisive, because fundamentally it is an article of faith. Are we more likely to keep the peace by getting rid of such weapons unconditionally or by showing a potential enemy that it would be too dangerous to attack us with their nuclear weapons or other weapons of mass destruction?

[Mr Leech]

What does the hon. Gentleman think the answer would be if we asked the general public whether they would prefer to dump Trident rather than sack soldiers?

[Dr Lewis]

I think it would depend on the extent of the debate that had taken place before the question was asked. I would be confident that if there were to be a debate on the subject, the public would come to share my view that no amount of conventional forces can be adequate to prevent an attack on us by an enemy armed with weapons of mass destruction if we lack the means to retaliate in similar terms.

While I am dealing with the hon. Gentleman’s intervention, let me return to a point that he made earlier in an intervention on the hon. Member for Islington North. He pointed out that nuclear weapons and nuclear deterrence had not abolished war, and that wars continued all over the planet. That is not an argument against nuclear deterrence; it is an argument in favour of it. After the second world war, if we had lived through 50 years of hostility between the then Soviet bloc and the west and there had been no conflicts anywhere in the world in which the nuclear balance of terror did not apply, one could indeed make the case that the nuclear balance of terror had had nothing to do with the prevention of war. The reality was that proxy wars were being fought by client states of the superpowers during the cold war, but the one thing that the superpowers never dared to do was to fight against one another directly, because they knew the potential outcome of all-out war between nuclear-armed powers.

Why is it important to have a debate on the matter, even though public opinion is fairly settled and parliamentary opinion is fairly relaxed? There are two reasons.
