ABSTRACT
If any book can be compared to Morgenthau's Politics Among Nations for its paradigmatic function in the discipline of International Relations, showing a model to follow and clustering central debates, then it is Kenneth Waltz's Theory of International Politics (Waltz 1979). Therefore, as in Part I with Morgenthau, the opening chapter on a new round in realist theorizing refers mainly to this single work and the debate it spurred.
