This edition of Global Trends revolves around a core argument about how the changing nature of power is increasing stress both within countries and between countries, and bearing on vexing transnational issues. The main section lays out the key trends, explores their implications, and offers up three scenarios to help readers imagine how different choices and developments could play out in very different ways over the next several decades. Two annexes lay out more detail. The first lays out five-year forecasts for each region of the world. The second provides more context on the key global trends in train. This report involves extensive research and consultations with people inside the US government and around the world. Their team made extensive use of analytic simulations to explore future trajectories and developed multiple scenarios to describe how key uncertainties and emerging trends might combine to produce alternative futures. Foreign policy analysts, lawmakers, and students participating in global studies, politics of peace and conflict undergraduate level courses and statistics may be interested in this work.
