Collective defense

Definition

Collective defense is a security arrangement in which states agree to respond collectively to an attack against one of them, emphasizing mutual protection and solidarity. This principle is central to various international alliances, such as NATO, where member countries commit to defend each other, reinforcing the idea that an attack on one is an attack on all. It operates under the assumption that unified military action deters aggression and promotes stability among nations.
