The US military has over 255,000 actively deployed personnel in 156 countries and currently has over 800 bases on 63 countries worldwide. The underlying land surface area of these bases is estimated at 30 million acres (46,875 sq mi) – roughly equal in area to the country of Greece (which itself has 7 US military bases on its territory). With so many countries with active US military bases on them – it begs the question if these countries are truly sovereign nations at all.
