What is the function of the united nation on the concept of collective security?

The United Nations (UN) plays a crucial role in the concept of collective security by promoting international cooperation to prevent conflict and maintain peace. Through mechanisms like peacekeeping missions, diplomatic efforts, and sanctions, the UN seeks to deter aggression against member states and respond to threats to international stability. The UN Security Council is central to this process, as it can authorize collective action when a threat to peace is identified. Ultimately, the UN aims to foster a collective response to security challenges, reinforcing the principle that an attack on one member is considered an attack on all.
