Export controls on computers and microprocessors have been a politically charged subject for much of the last decade. This volume reaches three broad conclusions: (1) Current export controls on computers and microprocessors are ineffective, given the global diffusion of information technology and rapid increases in performance; (2) the United States should eliminate these Cold War controls and strengthen military and proliferation-related controls; and (3) the trends that make computer export controls ineffective could damage national security if the United States does not use new information technologies to retain its military advantage over potential opponents.
