"More than two decades after the fall of the Berlin Wall and the collapse of the Soviet Union, Welsh revisited the bold claims made by Francis Fukuyama and the prophets of progress, who declared the triumph of Western liberal democracy and the advent of a more peaceful world. She identifies four main fault lines that threaten global security and economic and social stability: the return of barbarism with the rise of ISIS, the return of mass flight with the Syrian refugee crisis, the return of Cold War with Vladimir Putin's Russia, and the return of staggering inequality within Western nations. A powerful and essential analysis of the world's most pressing contemporary crises."--Page 4 of cover.
