Under these complex circumstances regional names are less useful. They are more historical than an accurate gauge of operations. The Directorate of Intelligence, one of four directorates into which the CIA is divided, includes the Office of Near Eastern and South Asian Analysis (NESA). Its duties are defined as "support on Middle Eastern and North African countries, as well as on the South Asian nations of India, Pakistan, and Afghanistan." The total range of countries is in fact the same as the State Department's Near East, but the names do not correspond. The Near East of the NESA is the same as the Middle East defined in the CIA-published on-line resource, The World Factbook. Its list of countries is limited by the Red Sea, comprises the entire eastern coast of the Mediterranean, including Israel, Turkey, the small nations of the Caucasus, Iran and the states of the Arabian Peninsula.
