I disagree with the hon. Member, because the two situations do have parallels. In the South China sea, people are challenging Chinese sovereignty, and it has been proved not to have standing in international courts. At the moment, ambiguity is starting to arrive in our position over the Chagos islands. This treaty would remove it and remove cause for the Chinese navy to take advantage. Against this backdrop, I want to restate the tests that I set out in an earlier debate on this deal. Does the agreement protect our national security? Does it command the support of our allies and professional security community? Are the costs proportionate to the benefits? On each of these tests, the answer remains yes. Diego Garcia is a keystone of our joint security architecture in the Indo-Pacific. It is where UK and US forces operate together against terrorist threats. It is a logistics, communications and intelligence hub, and it is central to safeguarding the global trade routes on which our economy depends. Without a secure base, all of that is placed at risk. Our Five Eyes allies in Canada, Australia and New Zealand support this deal, and our strategic partner India supports this deal. I want to address briefly the noise around President Trump’s social media posts, which the Minister dealt with very well earlier. Social media is not statecraft. What matters is the settled position of the United States, its military leadership and its security agencies. On that, there has been clarity for some time. The Pentagon, the State Department and successive US Defence Secretaries—Republican and Democrat—have supported this agreement. As I said at the beginning, interconnectedness is incredibly important and we cannot ignore the fact that international opinion matters. Yes, the world has changed. Power today is exercised through force—hard power has become incredibly important—but it is also still exercised through legitimacy, alliances and rules. If we expect others to respect international rules where it suits us, whether in Ukraine or the South China sea, we cannot be seen to apply them selectively elsewhere, except in the supreme national interest.
