Strategic Defence Review

Lord Alderdice Excerpts

Wednesday 9th October 2024 Grand Committee

[Lord Alderdice (LD)]

My Lords, one of the early and welcome announcements by Prime Minister Sir Keir Starmer was that we were to have a new strategic defence review, and we are all gratified that the SDR is being led by the noble Lord, Lord Robertson of Port Ellen, to whom we are indebted for the debate today and for his wonderful introduction to it. He brings a great range of experience, as we all know.

I have previously appealed to the noble Lord in your Lordships’ House to see this review of defence in its widest sense, and I do so again today. There will, necessarily, be a focus on matériel, men and money, and this is right. We need to look at our military resources to see what we have and what we need in a world where the character of war is changing rapidly, as we see in the conduct of the war in Ukraine. I refer noble Lords to the International Relations and Defence Committee’s recently published report Ukraine: A Wake-up Call. It is a very good report. I will not repeat a lot of what it says because I know it has already been sent to the noble Lord, and indeed he played his own part in the earlier drafts of the report, so I know he is familiar with it.

Contrary to a lot of the writing from 10 or 15 years ago about new wars, the old forms of warfare have not disappeared—they are still there. It is rather the case that new ones have sprung into significance in addition to the old ones. Drone warfare, to which the noble Lord, Lord Howell of Guildford, just referred, has taken a dramatically increased significance, and our procurement must take this into account. However, as in some areas, bigger and more sophisticated is not always better. Our US allies, for example, have been using $2 million missiles to take out drones sent by the Houthis in Yemen at $2,000 a time. That is just not an economically viable strategy.

Our Ukrainian friends, too, have used ingenious tactics to make up for limited resources, not just in converting off-the-shelf drones for military use but, for example, in packing an old Cessna plane with explosives and flying it into Russia to explode in an oil terminal. They were aided by the low radar profile of this old plane, as the Russians designed their defences to deal with the more sophisticated, long-range, high-tech US missiles that they had been expecting. We need to be creative and imaginative—in a different way, of course—as well as to become more efficient and effective in our procurement.

I want to elaborate a little on the question of defence in its widest sense. One of the downsides of having a fully professional Army with a high reputation is that our population has come to feel that it can be safely left to the professionals to do all our defence for us. There is little appreciation not only of the level of danger, which we speak about in our report, but also that the population at large needs to play its part in national defence. That involves encouraging young people to join up and exploring recruitment, training and retention of part-timers, but it is also crucial that our people realise that the dangers that our country and our wider world face require all of us to be engaged.

The dangers against which we must develop our defences are not only military in nature. They include epidemic diseases and climate catastrophes, and some of them can be used and abused by our enemies. We were reminded of the need for more personnel to be trained and ready and available for service during the recent pandemic and widespread flooding. We needed people who could go out and do things, not just the best brains and the most advanced research technology. We needed people on the ground to manage the situation. That is why I seek some reassurance from the noble Lord and his colleagues that they will take seriously the need for more personnel.

It is not that I do not appreciate the technological requirements. I am particularly concerned that, with hypersonic weapons making their appearance and the terrifying prospect that they could soon carry nuclear warheads, to which human operatives cannot respond sufficiently quickly, there will be pressure to give over decision-making to artificial intelligence, as has already been done in the Middle East, for example, in identifying, tracking, targeting and killing human subjects. I cannot see how we can address this issue without a serious effort to achieve international limitations and regulations, however difficult that is. That means collaboration between the five permanent members of the UN Security Council. I know that, despite the current hostilities, there have been some lower-level conversations among scientists, but I ask the noble Lord to consider recommending that our Government engage directly with Russia and China, as well as with our allies. We did it during the Cold War to try to achieve limitations on nuclear weapons. AI and nuclear weapons as a combination make this an urgent initiative, especially for nuclear weapon systems.

Perhaps the most urgent request that I would make at this moment is that the noble Lord includes de-escalation as an essential feature of our approach to defence planning. If our only response to acts of aggression is to engage in ever higher levels of aggression, which then provoke a similar reaction, as we are currently seeing in the Middle East, the consequences can only end up being catastrophic. We need to think, work and plan for how we use diplomatic and other relations with our enemies, as well as our friends, in order to be able to de-escalate dangerous situations. That requires the deployment of appropriate resources to defend our country.

Finally, on resources more generally, our people, pundits, political leaders and perhaps even some on the military side have lived for some years with the illusion that our world was becoming a safer place, or at least a less dangerous environment. This is manifestly not the case. At the same time, we cannot draw on the imperial resources that were available during the last two global conflicts. Surely we need to consider seriously whether we must review the territory that we can realistically defend. The defence of our own people, our own country and our region, western Europe, is our greatest responsibility. Although we can also play some role in the wider world and some of our historical areas of responsibility, it may now be time to trim our ambitions to what we can actually do. Illusions about our capacities will not serve us well in protecting our people in a real war. We must focus on addressing the world, especially the world that is closest to home, as it is, not as we wish it was. I wish the noble Lord and his colleagues well as they do their best to help us with that challenging task.
