In the years just before and after the fall of the Berlin Wall, people from across the political spectrum in Europe and America celebrated a great achievement, felt a common purpose and, very often, forged personal friendships. Yet over the following decades the euphoria evaporated, the common purpose and centre ground gradually disappeared, extremism rose once more and eventually - as this book compellingly relates - the relationships soured too. Anne Applebaum traces this history in an unfamiliar way, looking at the trajectories of individuals caught up in the public events of the last three decades. When politics becomes polarized, which side do you back? If you are a journalist, an intellectual, a civic leader, how do you deal with the re-emergence of authoritarian or nationalist ideas in your country? When your leaders appropriate history, or pedal conspiracies, or eviscerate the media and the judiciary, do you go along with it?
