"The National Security Agency, whose Cold War research into code breaking and electronic eavesdropping spurred the American computer revolution, has become a victim of the high-tech world it helped to create. Through mismanagement, arrogance, and fear of the unknown, the senior military and civilian bureaucrats who work at the agency's headquarters, in suburban Fort Meade, Maryland, have failed to prepare fully for today's high-volume flow of E-mail and fibre-optic transmissions -- even as nations throughout Europe, Asia, and the Third World have begun exchanging diplomatic and national-security messages encrypted in unbreakable digital code. The N.S.A.'s failures don't make the headlines... Last month, General Hayden agreed to speak to me, at his unpretentious top-floor offices at Ops 2, the N.S.A. headquarters building. He is an affable spymaster, who laughs easily, offers no slogans, and promises no quick fixes... "The issue is not people but external changes. For the N.S.A., technology is a two-edged sword... In its forty-year struggle against Soviet Communism," Hayden noted, "the N.S.A. was thorough, stable, and focussed." Then he asked "What's changed?" and he answered, "All of that.""
