I will give way, but it will be for the last time as otherwise I will be in danger of taking too much time. [Interruption.] I thank my hon. Friend for his courtesy in resuming his seat.

I wish briefly to make four political points. The first political argument is that when people are asked whether it is safer for this country to continue to possess nuclear weapons as long as other countries have them, a large majority of the population consistently take the view that we should do so and that it would be unwise and dangerous to renounce them unilaterally. We can ask different poll questions that seem to point to a different answer, but when that question is asked, the answer is surprisingly consistent.

The second political argument is that in the 1980s, under cold war conditions, two general elections demonstrated the toxic effect of one-sided disarmament proposals on a party’s prospects of gaining power. The third argument is that it was and remains widely believed—this refers to the intervention made by my hon. Friend Henry Smith a few moments ago—that the nuclear stalemate of the cold war enabled all-out conflict between the majors powers to be avoided for 50 years, despite their mutual hostility and in contrast to what happened in those many regional theatres where communists and their enemies could and did fight without fear of nuclear escalation. The final political argument is that the ending of the east-west confrontation has not altered the balance of public opinion on this question. First, that is because a danger could easily re-emerge of a reversion to a confrontation of that sort. Secondly, it is because even today there are unpleasant regimes, such as Iran’s, on the point of acquiring nuclear weapons and some, such as North Korea’s, that have already done so.

The role of our strategic nuclear force remains what it has always been: to deter any power armed with mass destruction weapons from using them against us, in the belief, true or false, that nobody would retaliate on our behalf. The use of our deterrent consists of its preventive effect on the behaviour of our enemies. The actual launching of a Trident missile would mark the failure of deterrence and would presuppose that a devastating attack had already been inflicted on our country.

Because strategic nuclear deterrence is largely irrelevant to the current counter-insurgency campaigns with which the British Army has been involved, some senior Army officers have been suggesting that we must choose between fighting “the war” of the present and insuring against the more conventional prospect of state-versus-state conflict in the future. I say that that choice is unacceptable, and that the underlying message that the era of high-intensity, state-on-state warfare is gone for good is a dangerous fallacy. Every sane individual hopes that such warfare will never return, but to rely on that in the face of past experience would be extremely foolhardy. The lesson of warfare in the 20th century, repeated time and again, was that when conflicts broke out they usually took their victims by surprise. Obvious examples are: the failure to anticipate the first world war; the follies of the “10-year rule” from 1919 to 1932; and the entirely unanticipated attacks on Israel in 1973, the Falklands in 1982, Kuwait in 1990 and the United States in 2001. Conversely, and on a brighter note, the speed with which the Soviet empire unravelled from 1989 left even its sternest critics largely nonplussed.
