Low politics is a concept that covers all matters that are not absolutely vital to the survival of the state as the economics and the social affairs. The low politics are the domain of the state's welfare. It concerns all things about social or human security. This concept is the opposite of the high politics which concerns the state's survival and strict national security. Keohane and Nye describe that previously, the international relations were based on a simple interdependence scheme based on national security: high politics, and that nowadays the international relations are ruled by a complex interdependence based on domestic issues : low politics.
The classical realism theory of international relations only considers the high politics as relevant and completely rejects the low politics. The complex interdependence of the liberal theory considers the low politics as fundamental without rejecting the high politics.
