Bringing together major thinkers of our time, including Francis Fukuyama, Benjamin Barber, Noam Chomsky, Bhikhu Parekh and Fred Halliday among others, "Worlds in Collision" sets the agenda for the debate about the future of the world order in the wake of international terrorism and the war in Afghanistan. There is no agreement among politicians, journalists and commentators as to the shape of the future of world order in the aftermath of the terrorist attacks of 11 September 2001. No agreement, that is, on anything other than the simple fact that the world has changed. In this respect, the attacks on the World Trade Centre and the Pentagon have brought to a close the ill-defined "post" period that came after the Cold War.
