We return to yesterday’s discussion that raised questions about the U.S. increased military presence in Africa—both in terms of personnel and military installations. The Oct. 4 ambush of four special-operations troops in Niger has raised questions in Congress about “shadow” military operations in that and several other African countries that few in Congress seem to know anything about. Meanwhile, as many as 1,500 “advisers” and other military personnel are in about 34 African countries, and Niger will soon be home to a $100-million, U.S.-built drone base.
