This article examines how a state that chooses to authorize a resistance organization as part of its national defence plan in order to increase its national resilience legitimizes that organization through the three phases of pre-conflict, conflict and occupation, and resumption of sovereignty. It will demonstrate the necessity of a legal framework for its authorization to obtain both domestic and international legitimacy. It will also cover the necessity of compliance with the Law of Armed Conflict (LOAC) during hostilities. Furthermore, it will touch on how this legal framework functions on behalf of the legitimate government in occupied territory against an adversary by not allowing adversarial political consolidation, while also assisting in the prevention of the creation of competing organizations in occupied territory with goals that deviate from those of the sovereign and legitimate government.
