This book, offering a comprehensive and provocative collection of viewpoints from leading intellectuals from a number of countries, will help readers understand the ways in which worlds collided on September 11, 2001. Not only does it comprehensively address the first phase of the war against international terrorism, the book also looks at the wider regional and global ramifications. Worlds in Collision is about more than the war on terrorism, it is ultimately about different ways of conceiving international politics, and hence the possibilities for reshaping global order.
