All of this would provide little more than a moderately interesting insight into the inner workings of an influential institution, were it not for the historical subject matter that occasioned the dispute: Kissinger's possible role in the 1970 assassination of Chilean General René Schneider and in the Chilean coup of 1973, and Kissinger's possible relationship to Operation Condor. Kornbluh is the lead researcher on Chile at the National Security Archive (NSA), a research group at George Washington University. NSA has been the leader in using Freedom of Information Act (FOIA) requests to obtain U.S. government documents related to the U.S. role in Chile in the 1970s, and his book dealt in large part with what can be learned from these documents.
