Weakened US-UK alliance cohesion; Trump's erratic positions reduce American credibility in strategic partnerships. Mauritius gains leverage through UK-US disagreement. China benefits from discord in Western Indian Ocean positioning. US military interests in Diego Garcia remain contested despite lease agreement.
Similar to Cold War-era US policy inconsistencies under unpredictable administrations, where allied nations struggled to navigate shifting American strategic priorities, undermining collective security arrangements.

UK government spending
Indirect impact through potential defense spending increases, currency volatility in GBP/USD, and uncertainty affecting UK-US trade relations. Consumers may face higher costs if defense budgets expand or trade friction increases.
UK government faces uncertainty in long-term defense planning and budget allocation (£101M annual lease costs). Potential for renegotiation of the deal or US pressure to modify terms. May prompt UK to diversify strategic partnerships and reduce dependency on US policy consistency.
