Defence Policy: Deterrence

Earl Attlee Excerpts

Thursday 31st October 2024 Grand Committee

[Earl Attlee (Con)]

I am grateful to my noble friend Lord Trefgarne for introducing this Question for Short Debate. I used to read my father’s Hansard when my noble friend was a Minister in the Foreign Office and in the Ministry of Defence.

The noble Lord, Lord Harris of Haringey, is absolutely correct: this is not just about conventional military deterrence. He is right to be worried about the home base and society’s sentiments. If those things were damaged in a conflict, in the grey area, it could have devastating effects on our conventional operations.

I am sure that the answer to my noble friend’s Question is “yes, but”. Many noble Lords have touched on nuclear deterrence, where our defence posture and signalling are absolutely clear and effective. As we have seen, we have not been cowed by President Putin’s nuclear sabre-rattling in the conflict in Ukraine. I am pleased to observe that this Government are as sound as their predecessor on nuclear deterrence but, several years ago, the noble and gallant Lord, Lord Craig of Radley, observed that an inadequate conventional deterrent will result in the nuclear trip-wire being set too low. The noble and gallant Lord, Lord Stirrup, just asked the Minister about tactical nuclear weapons and deterrence; I look forward to his answer.

In conventional deterrence, our signalling is not positive or clear to any potential adversary. For instance, it is easy for a potential adversary to measure our land logistics capability and intent. They will note that we are still selling off perfectly serviceable, brand-new logistic vehicles to meet resource accounting and budgeting requirements. In the current situation, at the large scale of effort we ought to be able to deploy on land in 12 weeks, but I do not think we can do it at all at the moment.

I keep banging on about the essential need to undertake large-scale exercises out of area and overseas to demonstrate and test our conventional capability—or the capability that we should have. My noble friend Lord Harlech touched on the fact that the Russians regularly exercise with large numbers of troops. Yes, it is expensive to do and you can save money by not undertaking such exercises, but it is cheaper than increasing your capability and provides much more conventional deterrence. It also exposes any unrecognised weaknesses in your current capability. Currently, we have too few big exercises and the exercises we undertake are too short in duration, in order to save money.

Noble Lords must not be deluded by the wide range of military operations that we undertake all over the globe at small scale. We are now in the era of state-on-state conflict; that is what we need to deter. We will not achieve that through small operations and exercises, or the completely underresourced Armed Forces that the Minister inherited from the previous Administration.
