The world has changed. Rather than a clash of civilisations, the West now faces revolts from the margins, driven by widening economic divisions, rising global elites and dangerous environmental constraints. The emergence of global terrorist movements such as ISIS is indicative of a growing threat for which traditional military responses are simply not fit for purpose. At a time when the world adjusts to new international leadership - from Trump in the US to Macron in France - and as the balance of power starts to shift away from the West, this updated edition of Paul Rogers' acclaimed book looks at the new challenges facing global security, and how we might start to address them.
