Lord Houghton of Richmond (CB)

My Lords, I rise to speak in support of Amendment 1, to which I attach my name, and to reinforce the arguments made by my noble and gallant friend Lord Craig of Radley. This amendment is not moved by any wider purpose than common sense, and we trust that the Government will respond accordingly. Currently, the Bill makes no provision for the circumstances under which the requirement to pay an annual fee for the use of the Diego Garcia base is revisited in the event of the base becoming unusable for military purposes. My noble and gallant friend has already mentioned the potential risks to the utility of the base arising from an extreme environmental event, the future potential for a policy change by the United States and the potential for the technical obsolescence of the base to come about. I argue that concerns regarding potential legal initiatives to constrain the use of the base, particularly partial constraints deriving from nuclear exclusion agreements or the question of Mauritius as the sovereign power having to honour obligations for the authorisation of offensive operations from the base, should be added to that list of concerns. I fear that the greatest future concern should perhaps be the full or partial destruction of the base through military action by a hostile state. This might seem a surprising concern given the extremely remote nature of this base, but I have been to it. I argue quite strongly that the strategic importance of the base, its entirely militaristic purpose and its extreme remoteness from civilian life all combine to make it a highly vulnerable and attractive target. The principal tenets for the use of force in warfare are distinction, military necessity, humanity and proportionality. Pause for a moment to imagine the early stages of a global conflict, when a desire for escalation dominance prompts a hostile nation to destroy a western strategic asset as a proportionate response, with no risk of collateral damage to a civilian population, attracting relatively minor moral opprobrium but resulting in huge military benefit. I cannot think of an obviously better or more considered target than Diego Garcia. Many in the Chamber may think my concerns are drawn from the world of fantasy or nightmare, but do the last 72 hours not give serious cause for concern regarding our ability to predict with certainty the next two years of geopolitics, let alone the next 100? This treaty needs to cater far better for what the future might hold.
