The world changed fundamentally at the beginning of the twenty-first century as terrorism, war and financial collapse shook the West out of its complacency. So what happens now? Can peace and democracy prevail in our era of uncertainty? Will the US remain the world's greatest superpower - or could another nation take its place? Can capitalism continue to dominate amid corporate scandal and anti-globalization protest?

In this brilliant enquiry into politics, economics, war and peace, Bill Emmott, the world-renowned commentator who predicted the meltdown of Japan's economy, shows that only by looking back at the turbulent twentieth century can we confront the future. Provocative, incisive and utterly prescient, 20:21 Vision is essential reading for anyone who wants to know how we got here - and where we're going.
