I rise to support the motion, and I do so joylessly and with a heavy heart. Nobody can stand in a missile compartment of a ballistic submarine without a sense of terrible awe; our warheads have the capacity to destroy 40 million people. I know that everyone in the Chamber feels that responsibility extremely acutely, and that certainly goes for my right hon. and hon. Friends on the Front Bench and their predecessors.

I spent much of my 20-year naval career at the tail end of the cold war. The cold war is over, however, and one can say it was won. The cold war did not become a real war, in part because of the terrible weapons that we are discussing this afternoon. We must not be preparing to fight the last war. Right hon. and hon. Members throughout the House are right to say that tomorrow’s wars are likely to be asymmetric wars, hybrid wars, wars involving terrorism, or conflicts involving climate change that, as we sit here, we really cannot fully understand. However, simply because those threats exist, that does not mean that nuclear blackmail does not and will not exist.

I fully accept that there are shades of grey in this debate. I absolutely reject the absolutist positions taken by some commentators, and I fully understand and respect arguments in relation to opportunity costs, but we have to make a decision now. We have been here several times before. In 2006, under the Labour party, we conducted what was appropriately called a deep dive. In 2013, very largely thanks to the Liberal Democrats—it pains me to say so, but it is nevertheless true—we undertook an alternatives review and dealt with many of the issues involved. I have no doubt that we will discuss this afternoon the alternatives considered at that time.

In the time available, I would like to speak briefly about the two propositions of redundancy and reputation. Those are respectable arguments that deserve to be dealt with properly.

Before my hon. Friend speaks about those two crucial points, does he agree that the speech we have just heard from the hon. Member for Chesterfield (Toby Perkins) was a most powerful argument, based on core beliefs that he has clearly thought about deeply and for a long time? It should be compelling for those of our constituents who are not clear about the party lines on this issue.

My hon. Friend is right, and the speech by the hon. Member for Barrow and Furness (John Woodcock) was also extremely powerful.

The redundancy proposition holds that advancing technology will make the continuous at-sea nuclear deterrent redundant. It is supposed—despite all evidence to the contrary—that unmanned underwater vessels will appear and render our oceans transparent, but that is pure supposition. We cannot approach our defence on the basis of what might happen in the future. History is usually a guide in these matters, and this year we mark the centenary of the introduction of tanks into the battle space. We could have said then, “We must not develop this technology because of the possibility of sticky bombs and tank traps”, but we did not.

One lesson from history must be from Nye Bevan, who said as Foreign Secretary that he should not be sent

“naked into the conference chamber”.

What sort of emperor in new clothing would go into a conference chamber with President Putin, for example, and say, “I don’t have nuclear weapons—well, I have some nuclear-powered subs, but there are no weapons on them”?

The hon. Lady is right. I am enjoying the consensual nature of this debate—it is the House of Commons at its very best. In 1929, J. F. C. Fuller said that tanks would make infantry redundant. In a sense he was right, but his timeframe was completely wrong, and the infantry was adapted rather than abolished. The imminent end of manned fighters was confidently predicted in a 1957 Government White Paper. The important point, which the hon. Lady was trying to make, is that we cannot base our defence on what we imagine might happen.

The threat of cyber and of unmanned underwater vessels should invigorate our countermeasures and our attempts to detect and potentially disrupt aggressors. Nevertheless, just as the Lightning II joint strike fighter may have only half a life before it is rendered obsolescent, we must be open to the possibility that the Successor submarine may at some point over its long life be made obsolete. However, I do not think that a sufficient argument to deploy against the decision we will make today.

The second proposition that I want to touch on is that of reputation theory. The argument is that unilateralism will in some way raise our standing internationally, but that is hopelessly naive. Try saying that to people in Ukraine; try waving the Budapest memo at them. Many will say that had Ukraine not given up its share of the USSR’s nuclear armamentarium—about a third of it—when it became independent, its territory would now be assured and it would not have been invaded by Russia. I do not want to take that argument too far, because others will make counter arguments about the wisdom of Ukraine having nuclear weapons—personally, I am pleased it does not—but from the perspective of a state that is trying to face down an aggressor, that is a powerful argument.

Some say that if we cut our nuclear arsenal others will follow, but there is no evidence to suggest that that is the case. We have cut our arsenal dramatically in recent years, yet other states have increased theirs.

Finally, in this atmosphere of Brexit, when we are re-forging our links with other international organisations and operating in an outward-facing way that I find refreshing, we must think about our permanent membership of the UN Security Council. That membership is contingent on this country offering something. It may pain some right hon. and hon. Members to ponder this, but in large part our membership of that body is down to our continued possession of this terrible weapon.

Absolutely, I would support that move. I would love to have all the jobs that would come with that. We would be more than happy to have it and to build on our naval heritage in that way.

I assure my hon. Friend that all of us who represent constituencies in the south-west would be more than delighted if the work was transferred from Scotland to the south-west, in the event that our deterrent was to move.

Johnny Mercer Portrait Johnny Mercer

Absolutely. We are proud of our naval heritage in the south-west—we are very proud of the people we support, our servicemen and servicewomen, and we would be delighted to make their lives easier by providing the facilities the south-west affords. Locally, the deterrent means thousands of jobs in Plymouth and a continuance of the Plymouth naval tradition that makes so many of us so proud. It is part of the fabric of our city. To lose that would be disastrous for the communities I am here to represent.

Let us not abstain tonight. Let us not play to our home crowd. Let us stand up for Britain’s place in the world and renew our nuclear deterrent. I say to Opposition Members—not to Scottish National party Members, because I have been struck by their rather childlike interventions about Libya and Iraq, which are totally separate issues—that I know many of my friends on the Labour Benches are of a similar mind to me on this issue. To those who are not, I say that I do not believe they love the country less in any way than those who support the motion. However, all the things we come into politics for are nothing without national security, and that must come first. To deliver the causes that I know are so dear to them and to me, we must renew our nuclear deterrent.

All steps must be taken to ensure the safety of this country’s people. The highly skilled engineering jobs I have talked about cannot be risked. Now, with everything that is going on—not just last weekend, but in the past year—is not the time to lower our guard. The Prime Minister mentioned North Korea. Can we really lose our nuclear weapons at this time? In an ideal world, I agree that it would be great not to have nuclear weapons, but how do we disinvent something that has been invented? The Government must base their decisions on the reality they face; others have the luxury to do otherwise. Trident remains the ultimate deterrent against an attack by those who would harm this country and our people, as it has been for 60 years. The point was made earlier that the Trident system is never used. It is used, every single day. A nuclear deterrent does what it says. The Government’s first priority is to ensure the safety and security of the nation and its people, and that is why I will support the Government’s motion tonight. I will be proud to walk through the Lobby with colleagues from across the House.
