The correct answer is: "total war".
The expression total war is used to describe armed conflicts in which the totality of resources in a country are deployed (human resoures, military, industrial, agricultural, natural, technological, scientific, etc), focusing all of them on warfare over any other type of needs. Moreover, resources and infraestructure become military targets, independently on whether these are related to civilians or not. The distinction between combatants and civilians practically disappears. The principal aim is to destroy the infrastructures of the opponent at any cost.
