Contributor(s): Professor Matthew Connelly | For most of its history, the U.S. government’s commitment to transparency stood as a radical counter-example to the rest of the world. Washington, Madison, and Lincoln were in some ways as radical as Julian Assange in their commitment to transparency. During the Civil War, one hundred and fifty years before Wikileaks, the State Department routinely made public normally secret diplomatic correspondences. When the White House invoked executive privilege, legislators and citizens were remarkably determined in challenging it, and historians were unusually effective in exposing the self-interest hidden by official secrecy. More recent invocations of national security therefore stand in sharp contrast with America’s founders and their principles.
