Colonel Joseph Collins, USA (Ret.), PhD reviews The Lessons of Tragedy: Statecraft and World Order by Hal Brands and Charles Edel. In this excellent book, the focus is on great power politics. And the centrality of survival and security supports this approach. However, the international order has a number of important aspects beyond interstate security politics. The issues of international political economy, trade, globalization and regional/global organizations are a big part of the story. If you can read only one book on world order, says Collins, you would do well to read Lessons of Tragedy. Aristotle would salute your prudence.
