Diego Garcia emerges as critical US hub amid Iran war

Key Points:

• The war with Iran has highlighted the strategic importance of Diego Garcia, a remote U.K.-U.S. base in the Indian Ocean, as the Pentagon shifts logistics there following an Iranian strike on a U.S. installation in Bahrain.
• Diego Garcia supports U.S. carrier strike groups like the USS Abraham Lincoln, enabling air operations and enforcement of blockades, though its remote location requires longer supply routes to avoid vulnerable coastal facilities.
• The sovereignty of the Chagos Archipelago, including Diego Garcia, remains contested between the U.K. and Mauritius, with a 2025 treaty recognizing Mauritian sovereignty but allowing U.K. control of the base for 99 years; implementation has been delayed amid U.S. concerns.
• U.K. officials have limited U.S. use of Diego Garcia for defensive operations against Iran, rejecting offensive strike proposals and highlighting the complexities of sovereignty and military cooperation in the region.
• The USS Abraham Lincoln is nearing nine months of deployment in the Middle East, with plans underway to replace it amid logistical challenges and extended service member deployments, underscoring the ongoing military focus on the region.
