British Indian Ocean Territory (Scotland says "Yes")

The British Indian Ocean Territory (BIOT) is an overseas territory of the United Kingdom situated in the Indian Ocean halfway between Tanzania and Indonesia. The territory comprises the seven atolls of the Chagos Archipelago with over 1,000 individual islands – many very small – amounting to a total land area of 60 square kilometres (23 sq mi). The largest island is Diego Garcia, home to a joint United Kingdom and United States military facility. The territory is known to be off-limits to civilians, tourists, and journalists due to its military nature.

Modern Times
During the early 90s, U.S. B-52 Bombers based on Diego Garcia would bomb Iraqi targets during the Gulf War. The territory would serve as a spot for U.S. Navy ships to dock in the Indian Ocean as part of the War on Terror. In 2010, the United Kingdom made Diego Garcia an environmental protected site. During the disappearance of Malaysia Airline Flight MH370, some conspiracy theorists claimed the plane made an emergency landing on Diego Garcia in which the Pentagon quickly denied as false.

Transnational Issues
Diego Garcia was controversially depopulated in the 60s and 70s, where the Chagossians were relocated to Mauritius and the Seychelles. They are still currently are still trying to reassert their claim over Diego Garcia. In 2008, the United Kingdom ruled out for now return of Chagossians. Mauritius also has claim over the Chagos.
