General Assembly:The General Assembly is the main deliberative body of the UN, where all member states have a voice and can vote on resolutions, but it does not have the same binding power as the Security Council.
Veto Power: The veto power refers to the ability of any of the five permanent members of the Security Council (the US, UK, France, Russia, and China) to block any substantive resolution, significantly impacting decision-making.
Peacekeeping Missions: Peacekeeping missions are operations authorized by the Security Council to help maintain peace and security in conflict areas, often involving international troops and resources.
