This book contributes impressively to our understanding of how Russian hacking and social media messaging altered the content of electoral dialogue that contributed to Donald Trump's victory." -- Daniella R. Mehlman-Brightwell, West Liberty University, International Journal of Communication "A meticulous analysis of online activity during the 2016 campaign makes a powerful case that targeted cyberattacks by hackers and trolls were decisive." - Jane Mayer, The New Yorker "In her breakthrough new book Cyberwar, Kathleen Hall Jamieson applies her legendary skills to a forensic examination of the Russian hackers, trolls and bots who reshaped American public opinion through social media platforms, using data analytics to achieve maximum impact. Her masterful study provides a compelling answer to the question of whether Russia likely helped elect an American President." -- Andrea Mitchell, NBC News Chief Foreign Affairs Correspondent, MSNBC Anchor "Kathleen Hall Jamieson has performed a great service not just for politicians, journalists and curious citizens, but most important, for American democracy, by taking a scholar's approach to answering one of the most urgent and gnawing questions of our time: how did Russia try to influence the U.S. elections of 2016 and how much difference did that make? This is a must read for everyone who cares about the future of the American electoral system." -- Judy Woodruff, Anchor and Managing Editor, The PBS NewsHour "Kathleen Hall Jamieson mounts a strong challenge to the conventional wisdom that the Russia interference in the 2016 presidential race did not affect the outcome. Drawing on her expertise in presidential elections and how messages are received, she shows how the hacked emails influenced the media's focus and traces the powerful synergies between what the trolls were saying and what voters were ready to believe. It is hard to imagine a better application of careful scholarship to a central question for our country and deserves a wide readership." -- Robert Jervis, Adlai E. Stevenson Professor of International Politics, Columbia University "Offers a detailed and compelling case" -- The Washington Post "Jamieson's illuminating, timely Cyberwar is a major step forward in trying to understand the 'new' media order -- and how open this digital landscape is to malicious exploitation." -- Nature "Necessary reading for those interested in the democratic process and its enemies." -- Kirkus "In her breakthrough new book Cyberwar, Kathleen Hall Jamieson applies her legendary skills to a forensic examination of the Russian hackers, trolls and bots who reshaped American public opinion through social media platforms, using data analytics to achieve maximum impact. Her masterful study provides a compelling answer to the question of whether Russia likely helped elect an American Presiden "Jamieson's expertise in US political communications allows her to unfold what issues were raised, made important, gained traction, and mattered in the back and forth between candidate messaging, media coverage, and voter engagement. Her very title announces the severity and malign intention of the activities she describes." --Katherine Voyles, Public Books
