Much of the dissatisfaction is directed at the structural turn that realist theorizing took with the publication of Kenneth Waltz's Theory of International Politics (Waltz 1979). Richard Ned Lebow puts the issue most forcefully: “There is widespread recognition that the realist tradition reached its nadir in neorealism.
