War

War is a conflict between political entities - states, tribes, political groups, and so on - occurring on the basis of various claims, in the form of armed confrontation, military (combat) actions between their armed forces.

As a rule, war is a means of imposing one's will on the enemy. When one subject of politics tries to change the behavior of another by force, to force him to give up his freedom, ideology, property rights, to give up resources: territory, water area and more.

"War is the continuation of politics by other, violent means" - so said Karl Philipp Gottlieb von Clausewitz
