"Echelon" is the name given to an alleged global eavesdropping network maintained by the U.S. and three 'Anglo-Saxon' allies. One ally, New Zealand, publicly admits that it is a "member of a long-standing collaborative international partnership for the exchange of foreign intelligence and the sharing of communications security technology." with the U.S. and two other nations. The European Parliament has taken up Echelon as a cause celebre. While the Europeans worry about "Echelon's" intrusions, the U.S. worries about declining capabilities at the National Security Agency, which is responsible for intercepting foreign communications. The most important questions, however, have to do with transatlantic and European cooperation.
