The National Security Archive at George Washington University is the largest independent non-government collection of declassified US documents and a goldmine of primary sources for scholars of US-Russia relations. Tom Blanton, director of the National Security Archive, and Dr. Svetlana Savranskaya, a senior analyst and director of the Archive’s Russia programs, share what they have uncovered about post-Cold War politics, the context behind Russia’s invasion of Ukraine, and the US government information classification system itself.
