Collective defense

Collective defense is a security arrangement where a group of nations agrees to protect each other in case one member is attacked. This means that if one country faces aggression, the others will respond together to defend it, effectively treating the attack as an attack on all members. A well-known example of collective defense is NATO (North Atlantic Treaty Organization), where an attack on one member triggers a collective response from all. This principle promotes unity and deterrence against potential aggressors by demonstrating that a group of nations stands together in defense of each other.
