This week on Lawfare's Arbiters of Truth miniseries on disinformation, Evelyn Douek and Quinta Jurecic spoke to Nina Jankowicz, a disinformation fellow at the Wilson Center, about her new book: “How to Lose the Information War: Russia, Fake News, and the Future of Conflict.” The book chronicles Nina’s journey around Europe, tracing down how information operations spearheaded by Russia have played out in countries in the former Soviet bloc, from Georgia to the Czech Republic. What do these case studies reveal about disinformation and how best to counter it—and how many of these lessons can be extrapolated to the United States? How should we understand the role of locals who get swept up in information operations, like the Americans who attended rallies in 2016 that were organized by a Russian troll farm? And what is an information war, anyway?
