defense treaties
Mutual security agreements
Defense treaties are formal agreements between nations pledging mutual military support if one is attacked.
The core principle is collective security—an attack on one member triggers a response from all.
NATO's Article 5 is the most prominent example: The alliance invoked its defense treaty after the September 11 attacks.
Such treaties aim to deter aggression by raising the stakes for potential attackers.
