For decades, American foreign policy has been based on the seductive belief that there exists a logical relationship between power of states and the physics of change. And yet today policies designed to make us safer instead make the world more perilous. History's grandest war against terrorism creates more terrorists. Global capitalism, intended to boost the quality of life of people around the world, increases the gap between rich and poor. Decisions taken to stem a financial crisis guarantee its arrival. Environmental techniques engineered to protect species lead to their extinction. Middle East peace plans produce less peace. Our world is not becoming more stable or flatter or easier to comprehend. And what we face isn't one single shift, like the end of World War Two or the collapse of the Soviet Union, so much as a revolutionary avalanche of ceaseless change. Now, drawing upon history, economics, complexity theory, human immunology, psychology and his own extraordinary experiences, Joshua Ramo puts forth a radical new model for looking at the world, one that embraces its inherent unpredictability--and offers our best hope for dealing with problems and disasters as they emerge.
