This edited book explores the multi-layered relationships between public diplomacy and intensified uncertainties stemming from transnational political trends. It is the latest wave of political uncertainty that provides the background as well as yields evidence scrutinised by authors contributing to this book. The book argues that due to a state of perpetual crises, the simultaneity of diplomatic tensions and new digital modalities of power, international politics increasingly resembles a networked set of hyper-realities. Embracing multi-polar competition, superpowers such as Russia flex their muscles over their neighbours; celebrated 'success stories' of democratisation - Hungary, Poland and Czechia - move towards illiberal governance; old players of international politics such as Britain and America re-claim "greatness", while other states, like China, adapt expansionist foreign policy goals. The contributors to this book consider the different ways in which transnational political trends and digitalisation breed uncertainty and shape the practice of public diplomacy.
