This short book explores the new world of the early 21st century. Cooper sees the defining moment in the end of the Cold War in 1989, which changed the state system that had defined world politics since the treaty of Westphalia, and that a new world is emerging with new challenges. This premise is quite generally accepted, but it is more interesting when he qualifies the new world order as a mixture between the old and the new, where new security threats/challenges are emerging in a world divided between "pre-modern", "modern" and "post-modern" states.
The challenges and solutions in the new world order lie in the interrelations between these types of states.
The most interesting part of the book is when Mr. Cooper enumerates his five maxims for conditions for world peace: (1) the need to understand "foreigners" better (being a foreigner myself in relation to Mr. Cooper, I would rather change the argument to understanding one another...); (2) the primacy of domestic politics; (3) the difficulty in influencing foreign governments; (4) the definition of interests in international relations; (5) redefinition the concept of identity in international relations.
The more detailed discussions of each of these maxims are extremely insightful and interesting, but I found his argumentation in line with social-constructivist models of international relations, that states identity is the most important thing in defining interests, extremely useful and relevant for the understanding of international politics: "Much more important than the question of how countries pursue their interests is the question of how they define them" (page 137).
Mr. Cooper's road to condition for peace in the 21st century is not one of a question between a balance of power or of power-hegemony (he completely parts with Mr. Kissinger in this regard), but states that it is about reaching a post-modern collective security model, where his clear source of inspiration is the European Union, which has achieved an unprecedented level of peace in only 50 years, but after centuries of bloody conflict. He is not blind to the challenges and difficulties though; Mr. Cooper is not a naïve pacificist, nor a hard-core "realist", and that is perhaps what makes him most in touch with reality in his argumentation: peace can be achieved, but one must not forget that there are real threats and dilemmas in balancing them, and that the use of military force should never be excluded as the "continuation of politics by other means" for the achievement of legitimate goals.
One can see the huge level of academic research behind the book and the argumentations: he obviously knows his history and theories of international relations, and that makes the book is suberbly well-written, getting around such broad issues in a coherent and brief manner that it can make the often too-academic and heavy literature on these subjects so simple, accessible and yet without losing the balance and seriousness of the issues at hand.
Fabulous book.
