Trump's 5 reasons for wrecking Chagos deal – he smells blood with 'lame duck' Starmer



President Trump has reportedly moved to block the proposed agreement to transfer sovereignty of the Chagos Islands to Mauritius, placing additional pressure on Prime Minister Keir Starmer at a politically fragile moment in the UK.

According to reports, Trump urged Starmer to reconsider the arrangement, signaling that Washington wants a stronger say in decisions affecting Diego Garcia the strategically vital US-UK military base in the Indian Ocean. With Starmer facing mounting domestic political challenges, the intervention adds a new layer of complexity to the transatlantic relationship.

Here are five key factors shaping Trump’s opposition to the deal:

1. Strategic competition with China

Many officials in the Trump administration view the Indo-Pacific as the central arena of long-term competition with China. Diego Garcia plays a critical role in projecting US military power across the region. Any agreement that could introduce uncertainty about long-term basing rights is likely to face resistance from defense officials focused on maintaining strategic leverage.

2. Influence from UK critics of the agreement

The proposed transfer has drawn criticism from several British political figures, including Nigel Farage and some Conservative MPs. These critics argue the deal could weaken the UK’s geopolitical standing. With established relationships in US political circles, their concerns may be resonating with Trump and his allies, reinforcing skepticism inside Washington.

3. Broader debates about territorial sovereignty

Trump has frequently emphasized strong national control over strategic territory. His past comments about Greenland underscored his view that geography and military positioning are core components of national power. From that perspective, the decision by a close ally to transfer sovereignty over a key territory may clash with his broader strategic instincts.

4. Frustration with European defense posture

Trump has consistently criticized European governments for what he sees as insufficient defense spending and overreliance on US security guarantees. Some in Washington may interpret the Chagos agreement as part of a wider pattern of European retrenchment at a time of heightened global tensions, particularly involving Russia.

5. Signaling toward Iran

Diego Garcia has historically played a role in US operations in the Middle East. Trump has linked the base to potential deterrence against Iran amid ongoing disputes over Tehran’s nuclear ambitions. Reasserting control over its future may serve as a broader signal of resolve in that context.

The situation underscores the delicate balance between international law, domestic politics, and great-power strategy. Whether the agreement proceeds may depend not only on negotiations between London and Mauritius, but also on how firmly Washington chooses to assert its position in the weeks ahead.
