3. Self-defense in national defense.

In the context of Juche, which is North Korea's guiding philosophy emphasizing self-reliance, self-defense in national defense refers to the idea that a nation must actively protect itself from external threats to ensure its sovereignty and independence. This means prioritizing military strength and preparedness as a crucial aspect of national identity and survival. Juche advocates for building a robust defense system and maintaining autonomy in decision-making, reflecting a belief that true safety comes from self-sufficiency rather than relying on others for protection. This concept underscores the importance of national pride and resilience in the face of perceived aggression.
