For questions about armed or cyber conflicts between different countries, or civil conflicts within countries, or conflicts between sects, non-government actors, such as terrorist groups.

War is not simply confined to nation states, nor is it simply confined to physical conflict. It can be carried out by non-state actors, sects within a state, ethnic minority groups, and groups that transcend national boundaries. And it is not limited to kinetic arms but must include cyber technologies and non-traditional usage of strategic deterrence and/or forces perpetuated by one onto another. War is of scale, both temporarily and by the amount of force used. And as Clausewitz stated, war is foreign policy by other means.
