Collective punishment means imposing harm on an entire civilian population to pressure their government, rather than targeting combatants or military objectives. Article 33 of the Fourth Geneva Convention prohibits collective punishment: "No protected person may be punished for an offense he or she has not personally committed." Deliberately targeting water, food, or power infrastructure that civilians depend on to survive is one form collective punishment can take in warfare. International law distinguishes between legitimate military pressure on a state's war-fighting capacity and deliberate harm to civilians used as a coercive tool.
