A Mutual Defense Pact is a formal agreement between two or more countries to provide military support to each other in the event that one of the parties is attacked. Such pacts are designed to deter potential aggressors by ensuring that an attack on one member will result in a collective response from all signatories. These agreements often outline the scope of assistance, which can include military, logistical, or intelligence support, and may specify the conditions under which the pact is activated. Mutual Defense Pacts are foundational to many international alliances, such as NATO, and play a critical role in global security by promoting collective defense and stability.
