The United States and Spain have extensive cultural ties and a mutually beneficial economic relationship, and the two countries cooperate closely on numerous diplomatic and security issues. Spain has been a member of the North Atlantic Treaty Organization (NATO) since 1982 and a member of the European Union (EU) since 1986. Given its role as a close U.S. ally and partner, developments in Spain and its relations with the United States are of continuing interest to the U.S. Congress. This book provides an overview and assessment of some of the main dimensions of these topics. This book also discusses Spain's 2014 Human Rights Report; International Religious Freedom Report; and its 2015 climate statement.
