War is a conflict between groups, often countries, that involves organized military forces. It typically arises from disputes over territory, resources, or political power. The consequences of war can be devastating, leading to loss of life, destruction of infrastructure, and long-lasting social and economic impacts. Throughout history, various types of warfare have emerged, including conventional warfare, guerrilla warfare, and cyber warfare. International laws, such as the Geneva Conventions, aim to regulate the conduct of war and protect those not participating in the conflict, including civilians and prisoners of war.
