An armed conflict between state actors, typically for a political or economic aim. Use this tag for specific wars.
War is an organized, armed, and, often, a prolonged conflict that is carried out between states, nations, or other parties typified by extreme aggression, social disruption, and usually high mortality. War should be understood as an actual, intentional and widespread armed conflict between political communities, and therefore is defined as a form of political violence.
For wars in general or the techniques used in its conduct, use warfare.
