Collective Defense Theory

Collective Defense Theory is the idea that countries can enhance their security by forming alliances. When one member of an alliance is threatened or attacked, other members agree to support them, often militarily. This principle is famously embodied in NATO, where an attack on one member is considered an attack on all. The theory operates on the premise that mutual protection discourages aggression, thereby promoting peace and stability. Essentially, it's about pooling resources and ensuring that nations have backup in times of crisis, making it less likely for threats to escalate into larger conflicts.
