Recent geopolitical tensions have escalated sharply following an attempted Intercontinental Ballistic Missile (ICBM) attack by Iran on the joint US-UK military base at Diego Garcia.  

About Diego Garcia 

Diego Garcia is a coral atoll in the central Indian Ocean, serving as a critical military outpost for the United Kingdom and the United States 

Geography and Features

  • Location: Situated approximately 1,796 km south of India and 3,535 km east of Tanzania.
  • Archipelago: It is the largest and southernmost island of the Chagos Archipelago.
  • Shape: A distinctive horseshoe or footprint-shaped coral atoll enclosing a deep natural lagoon.
  • Topography: Extremely low-lying, with an average elevation of just 1.2 metres above sea level. 

Strategic and Military Significance

Diego Garcia is often called the "unsinkable aircraft carrier" due to its role as a forward-operating base. 

  • Power Projection: Its central location allows rapid military reach across West Asia, East Africa, and Southeast Asia.
  • Facilities: Hosts a 3,700-metre runway capable of supporting B-52, B-1, and B-2 stealth bombers. Its deep-water harbour accommodates aircraft carriers and pre-positioned supply ships.
  • Key Operations: Used as a launchpad for the Gulf War (1991) and operations in Afghanistan and Iraq.

The Sovereignty Dispute & 2025 Treaty

Historical Context: In 1965, the UK separated the Chagos Archipelago from Mauritius to form the British Indian Ocean Territory (BIOT).

Displacement: Between 1968 and 1973, the indigenous Chagossian (Ilois) population was forcibly removed to make way for the military base.

ICJ Ruling (2019): The International Court of Justice (ICJ) ruled that the UK's administration was unlawful and that the islands should be returned to Mauritius.

Sovereignty Treaty (2025): The UK and Mauritius signed a landmark treaty where the UK agreed to transfer sovereignty of the Chagos Islands to Mauritius.

  • The Caveat: The UK will retain control of the military base on Diego Garcia for at least 99 years under a lease agreement.

Frequently Asked Questions (FAQs)

Diego Garcia is a strategically located island in the Indian Ocean functioning as a crucial staging ground for US-UK military operations, strategic bombers, and intelligence. Its extended reach allows for robust force projection across the Middle East, Africa, and the Indo-Pacific.

The Strait of Hormuz is the world’s most important energy transit corridor, facilitating the movement of roughly 25% of all global seaborne oil trade and 20% of global oil consumption. Any disruption here drastically threatens global energy supplies and causes severe oil price volatility.

India imports over 85% of its crude oil, heavily relying on the Middle East. Geopolitical escalations cause crude prices to surge. A sustained $100/barrel oil price widens India’s current account deficit (CAD), imports inflation, disrupts business sentiment, and depreciates the Rupee.
