Free War

Free war is a term used to describe an armed conflict that is not between two states, but instead between a state and a non-state actor, such as a terrorist group or a rebel militia. It is also used to describe civil wars, which may involve two or more parties within the same country. In a free war, the state may have to use its military forces to protect its citizens or its borders, or it may seek help from other countries or international organizations.
