  What Waltz and other neorealist readers of Hobbes’s works sometimes overlook is that he does not perceive international anarchy as an environment without any rules. By suggesting that certain dictates of reason apply even in the state of nature, he affirms that more peaceful and cooperative international relations are possible. Neither does he deny the existence of international law. Sovereign states can sign treaties with one another to provide a legal basis for their relations. At the same time, however, Hobbes seems aware that international rules will often prove ineffective in restraining the struggle for power. States will interpret them to their own advantage, and so international law will be obeyed or ignored according to the interests of the states affected. Hence, international relations will always tend to be a precarious affair. This grim view of global politics lies at the core of Hobbes’s realism.
