Power politics is a theory of power in international relations which contends that distributions of power and national interests, or changes to those distributions, are fundamental causes of war and of system stability.[1][additional citation(s) needed]
The concept of power politics provides a way of understanding systems of international relations: in this view, states compete for the world's limited resources, and it is to an individual state's advantage to be manifestly able to harm others. Power politics prioritizes national self-interest over the interests of other nations or the international community, and thus may include threatening one another with military, economic, or political aggression to protect one nation's own interest.[citation needed]
