In a move that reeks of diplomatic naivety and strategic cowardice, British Prime Minister Keir Starmer has overseen a deal that hands over the Chagos Islands to Mauritius, leasing back the critical Diego Garcia military base at an astronomical cost to British taxpayers. This agreement, signed on May 22, 2025, not only undermines Britain’s global standing but also raises serious questions about Starmer’s judgement, particularly regarding the use of U.S. military assets stationed at Diego Garcia and their potential role in addressing Iran’s nuclear ambitions. Worse still, it remains unclear whether Starmer has fulfilled his treaty obligations to inform Mauritius of any planned U.S. military actions from the base, a requirement that could compromise operational security in a volatile region. This article dismantles Starmer’s reckless decision, exposing its flaws and highlighting the military implications of this so-called “deal.”
The Chagos Deal: A Financial and Strategic Fiasco
Starmer’s agreement to cede sovereignty of the Chagos Archipelago to Mauritius, while leasing back Diego Garcia for 99 years at a cost of £101 million annually (potentially totalling £30 billion over the lease period), is nothing short of a financial and strategic disaster. The deal, ostensibly struck to comply with a 2019 International Court of Justice (ICJ) advisory opinion, was framed by Starmer as a necessary step to secure the Diego Garcia base from legal challenges. Yet, this narrative crumbles under scrutiny. The ICJ’s opinion was non-binding, and Britain could have continued to assert its sovereignty while negotiating from a position of strength. Instead, Starmer’s government capitulated, agreeing to pay Mauritius exorbitant sums—£165 million annually for the first three years, £120 million for the next decade, and inflation-adjusted payments thereafter—while Mauritius uses the windfall to fund tax cuts and debt repayments for its citizens.
This financial burden on British taxpayers is egregious enough, but the strategic implications are far graver. Diego Garcia, a joint UK-U.S. military base, is a linchpin of Western power projection in the Indian Ocean, located just 5,300 kilometres from Iran. Its strategic value lies in its ability to host heavy bombers and support operations across the Middle East, free from the constraints of Gulf airspace. Under the deal, the UK retains operational control of Diego Garcia, but Mauritius’s sovereignty introduces new vulnerabilities, including the requirement to notify Mauritius of any military actions launched from the base. This clause, buried in the treaty’s fine print, could jeopardise the secrecy and efficacy of military operations, particularly in a potential conflict with Iran.
U.S. Military Assets at Diego Garcia: A Critical Arsenal
Diego Garcia is not just a speck in the Indian Ocean; it is a fortress of military might. The base hosts a range of U.S. aircraft critical to regional and global security. Recent reports confirm the presence of four B-52 Stratofortress bombers, capable of carrying precision-guided bombs and cruise missiles, spotted on Diego Garcia’s runway on June 16, 2025. Additionally, speculation surrounds the potential deployment of B-2 Spirit stealth bombers, which can carry bunker-busting munitions like the GBU-57 Massive Ordnance Penetrator, designed to target deeply buried facilities such as Iran’s Fordo nuclear enrichment plant. These assets underscore Diego Garcia’s role as a staging ground for potential U.S. or joint U.S.-Israeli strikes on Iran’s nuclear infrastructure, a prospect that has grown more likely amid escalating tensions following Israel’s attacks on Iran in late May 2025.
The base’s strategic importance cannot be overstated. Its isolation allows for secure operations, and its proximity to the Middle East enables rapid response capabilities. Yet, Starmer’s deal introduces a dangerous wildcard: Mauritius, a nation with growing ties to China, Russia, and Iran, now has a say in the base’s operations. The requirement to notify Mauritius of any military actions, such as U.S. bomber strikes, risks leaking sensitive information to adversarial powers, potentially undermining the element of surprise critical to such missions.
Has Starmer Informed Mauritius? A Glaring Silence
The treaty’s notification clause is not a minor bureaucratic detail—it’s a potential operational disaster. As tensions with Iran escalate, with Donald Trump reportedly considering strikes on Tehran’s nuclear facilities, the question looms: has Starmer informed Mauritius of any U.S. intentions to use Diego Garcia for such operations? Posts on X have raised this concern, with users like @joerichlaw and @RossKempsell questioning whether Starmer and his National Security Advisor, Jonathan Powell, have complied with the treaty’s terms. Starmer’s government has remained conspicuously silent on this matter, offering no public confirmation of whether Mauritius has been notified of recent U.S. bomber deployments or potential plans for strikes on Iran.
This silence is damning. If Starmer has informed Mauritius, he may have already compromised operational security, given Mauritius’s diplomatic ties to powers hostile to Western interests. If he has not, he is in breach of his own treaty, undermining the deal’s legitimacy and exposing the UK to legal and diplomatic repercussions. Either way, Starmer’s handling of this issue betrays a lack of foresight and a failure to prioritise national security. The presence of B-52s and potential B-2s at Diego Garcia, combined with the treaty’s notification requirement, places Starmer in an impossible position—one entirely of his own making.
The Chagossian Betrayal: A Moral Failure
Beyond the strategic and financial costs, Starmer’s deal tramples on the rights of the Chagossian people, who were forcibly displaced from Diego Garcia in the 1960s and 1970s to make way for the military base. UN human rights experts have condemned the agreement for failing to consult Chagossians and for barring their return to Diego Garcia, violating their cultural and ancestral rights. The deal’s provision for a £40 million trust fund and potential resettlement on outer islands does little to address the Chagossians’ grievances, especially when Mauritius, not the UK, controls the terms of any return. Starmer’s claim that the deal was necessary to avoid legal challenges rings hollow when weighed against this moral failing, further tarnishing his legacy.
A Surrender to Adversaries
Starmer’s defenders argue that the deal secures Diego Garcia’s future by aligning with international law and U.S. support. Yet, this ignores the broader geopolitical context. Mauritius’s growing alignment with China, Russia, and Iran raises legitimate concerns that the deal could expose Diego Garcia to “malign influence,” precisely what Starmer claimed to guard against. Critics, including Conservative leader Kemi Badenoch and Reform UK’s Nigel Farage, have slammed the deal as a “surrender” that weakens Britain’s strategic position and emboldens adversaries. The suggestion that China might establish bases on outer Chagos islands, unhindered by the UK’s diminished sovereignty, is a chilling possibility that Starmer’s government seems ill-prepared to counter.
Conclusion: A Leader Out of His Depth
Keir Starmer’s Chagos deal is a masterclass in shortsightedness, trading Britain’s strategic leverage for a costly lease and a dubious promise of stability. The presence of U.S. B-52 and potentially B-2 bombers at Diego Garcia underscores the base’s critical role in countering threats like Iran’s nuclear program, yet Starmer’s treaty risks compromising these operations through its notification clause. His failure to clarify whether Mauritius has been informed of U.S. intentions only deepens the suspicion that he is either negligent or deliberately opaque.
Coupled with the deal’s financial extravagance and disregard for Chagossian rights, Starmer’s actions reveal a leader out of his depth, prioritising appeasement over strength. Britain deserves better than this capitulation, and the world cannot afford the consequences of such weakness.
