This book focuses on the proposition of state construction and discusses it at the two levels of national governance and world order. The main points of this book: State-building is one of the most important propositions, because weak or failed states have become the root of many serious problems in the world today; the scope of state functions should be streamlined, but the capabilities within the scope of state functions should be strengthened at the same time; how to transplant powerful systems to developing countries; the international community should pay attention to the art of post-event state-building when intervening in other countries. In short, building a small but strong country is not only the goal of the nation-state itself, but also the goal of the international community's assistance or intervention. From the analysis of the concept of state, to the introduction of organizational theory, to reflection on political reality, Fukuyama completed a complete discussion of state construction.
