Defence Policy: Deterrence

Baroness Smith of Newnham Excerpts

Thursday 31st October 2024 Grand Committee

[Baroness Smith of Newnham (LD)]

My Lords, like other noble Lords, I thank the noble Lord, Lord Trefgarne, for enabling us this afternoon to talk about deterrence and core aspects of UK defence. The noble Baroness, Lady Goldie, the noble Lord, Lord Coaker, and I keep meeting in this venue. We talked about the SDR two weeks ago, we were here again last week, and we are going to meet again in an hour to talk about defence expenditure—so I am not going to touch on defence expenditure, as did the noble Earl, Lord Attlee, and the noble Lord, Lord Bilimoria. I want to pay tribute to the noble Lord, Lord Coaker, and the new defence team, because one concern that the noble Lord, Lord Trefgarne, implied was that the new Government might not be serious about deterrence or about defence.

On Tuesday evening, as a trustee of the Armed Forces Parliamentary Trust, which runs the Armed Forces Parliamentary Scheme, I was at a graduation dinner. Present were the noble Lord, Lord Coaker, because he had been part of the scheme, the noble Baroness, Lady Chapman of Darlington, and Luke Pollard, Min AF. We have among our ministerial ranks people have previously taken the time from the Back Benches or from opposition to ask what defence is all about. It is important to realise that the Government are saying on defence and deterrence almost exactly the same as the previous Conservative Government and almost the same as the Liberal Democrats. We are now all committed to CASD and to the defence of the realm, and we understand the importance of deterrence.

On deterrence and preparedness, which we heard about from the noble Lord, Lord Harris of Haringey, and given that I am winding for the Liberal Democrats, I remind noble Lords of the importance not just of defence commitments but of diplomacy and development, because if we establish the right relationships before we end up in a state where we need to prepare for war, we might make better use of the British budget. Deterrence is important, CASD matters, but so do our alliances, such as NATO and the bilateral relationships which this Government are seeking to build and foster. That is all incredibly important, yet, as we have heard from various noble Lords, the challenges we face in the 21st century are rather different.

In his incredibly important contribution, the noble and right reverend Lord, Lord Harries of Pentregarth, reminded us about a range of issues that we need to think about in nuclear policy and, more broadly, about discrimination and proportionality. He reminded us that our nuclear posture was initially determined in a period of balance: the Cold War, when mutually assured destruction meant that it was unlikely that any side would use a nuclear weapon. They had their deterrent function. In the current world, we face not just state-based threats but threats from non-state actors; not just conventional threats but cyber and hybrid threats. In respect of naval policy, we have the noble Lord, Lord West, repeatedly banging the drum for maritime. Who is banging the drum to deal with hybrid threats and cyber, and to ensure that we have a fully-fledged deterrent alongside our nuclear deterrent?
