There are US Military Bases in many countries undertaking different functions. Gunatanemo in Cuba is notorious for holding prisoners with out charge for long periods of time. A US naval base being constructed on South Korea's Jeju Island has destroyed unique rock formations and displaced local people as well as rising tensions with China. The enforced removal of the Chagos Islanders to make way for a US naval and military base of Diego Garcia has raised many ethical and legal questions. Japanese activists have strongly objected to the establishment of new US military bases in Japan.
