"Cabo Verde, a small island nation of just over half a million people located off the west coast of Africa, is of strategic significance to the United States because its geographic location has made the country a transshipment point for Latin American cocaine bound for Europe and a key refueling stop-over for trans-Atlantic air traffic between Africa and the United States. The country is also a long-standing U.S. ally in Africa that the State Department has cited as a model of democratic governance in the region since its transition from single party rule to a multi-party political system in 1991. U.S. bilateral aid to Cabo Verde is limited, and centers on military professionalization, counternarcotics efforts, and development projects supported by the Millennium Challenge Corporation (MCC)."
