UK Defence Spending — House of Commons, 2021-06-24
Topic: Defense
Julian Murray Lewis (Independent, Unknown): Let us see if the hon. Gentleman was right in anticipating what I have to say In the absence, at present at any rate, of any briefing on the issue, classified or otherwise, from my parliamentary colleagues on the Defence ministerial team, here are the four possible explanations that occur to me. Explanation 1—most probably, as already stated—is that it is an insurance policy to prevent a potential aggressor from calculating that advances in anti-ballistic missile systems have reduced our retaliatory capability to a point where our response to an attack becomes bearable or even avoidable. Explanation 2—quite probably—is that it is to give more headroom for the time, in the late 2030s or early 2040s, when we are due to exchange our current stockpile of warheads for next-generation nuclear warheads, while at the same time preventing disruption of our continuous at-sea deterrent patrols. Explanation 3— possibly—is that it is to send a signal internationally that the UK is determined to keep nuclear weapons as long as other countries have them and remains committed to doing whatever is required to maintain their invulnerability. And—here it comes—explanation 4, conceivably, is that it is also tailored for a domestic audience worried about cuts in the size of the Army, in order to offer reassurance, or at least to divert some attention from those reductions What seems most unlikely is an intention to invest in additional warheads of the existing design. We are certainly cancelling their reduction from a theoretical maximum of 225 to one of only 180 for any or all of the four reasons listed, particularly the first explanation. Raising the maximum from 225 to 260 to provide extra headroom for the eventual transition from current warheads to their replacements is a sensible explanation, though not a conclusive one, given that the changeover is not due to happen for well over a decade Despite the imposition of a dedicated supporter of the Campaign for Nuclear Disarmament as the Leader of the Opposition in 2015, hon. and right hon. Labour Members ensured that their party’s policy remained multilateralist. Previously, on 14 March 2007, Parliament had voted by 409 to 161 in favour of proceeding with the initial gate for renewal of the Trident submarine fleet. Even that huge majority was eclipsed on 18 July 2016, when it rose to 355 after MPs voted for the decisive main gate stage to proceed by 472 to only 117 There is nothing in article VI of the non-proliferation treaty that requires any country already in possession of a recognised nuclear arsenal to get rid of it and to achieve a nuclear-free world prior to a state of grace when general and complete conventional disarmament—also referred to in the non-proliferation treaty, but seldom cited by those who quote it selectively—can be guaranteed. There is a very good reason for this, because if we were to abandon all nuclear weapons in an unreformed world, that would be a recipe for disaster. In a conventional war taking place in a nuclear-free world, the former nuclear powers would immediately race to reacquire the bomb. The first to succeed would then use its monopoly, as occurred in 1945. If the treaty’s vision of general and complete conventional disarmament ever becomes reality, then nuclear weapons can indeed also safely be declared redundant; but, until that day dawns, the United Kingdom is perfectly capable of changing the size of its warhead stockpile without breaching the non-proliferation treaty in order to maintain indefinitely the credibility of its strategic minimum deterrence policy.
