What is NATO?
The North Atlantic Treaty Organization (NATO) is an alliance established in 1949 by the Washington Treaty. It is headquartered in Brussels. Its core purpose is to safeguard the freedom and security of its members by political and military means. NATO is not a supranational government; it rests on the voluntary cooperation of sovereign states.
Core principles
- Collective defence (Article 5): An armed attack against one member is considered an attack against all. Each member decides for itself what assistance to provide; there is no automatic obligation to take part militarily.
- Consultation (Article 4): If a member believes its territorial integrity, political independence or security is threatened, it can request consultations with the other members.
- Open door: European states that embrace the treaty's principles and can contribute to security may be invited to join by unanimous agreement of the members.
How are decisions made?
NATO decision-making is based on consensus: there is no voting, and a decision is adopted if no member openly objects. This gives every member an equal voice regardless of its size.
- Agenda and preparationIssues are discussed in committees and by countries' permanent representatives to NATO.
- DeliberationDraft texts are reviewed, with objections and amendments considered.
- AgreementConsensus is reached in the North Atlantic Council; if there is no objection, the decision is final.
- ImplementationThe decision is carried out using members' resources and NATO's command structure.
Main bodies
- North Atlantic Council: The main political decision-making body. It can meet at the level of permanent representatives, ministers, or heads of state and government; decisions carry the same weight.
- Secretary General: Chairs the Council, leads consultations and is the alliance's chief spokesperson. This is a political role, not a military command.
- Military Committee and command structure: Provides military advice; allied commands carry out operations. Political control always rests with the Council.
Frequently asked questions
Does every member have an equal vote?
Since there is no voting, it is better described as an equal voice. No member's objection is set aside simply because it is small.
Does Article 5 mean automatic war?
No. Each member takes the action it ‘deems necessary’ at its own discretion; this may include armed force, but does not have to.
How is a new member admitted?
Accession talks proceed step by step, the invitation requires the agreement of all current members, and then members complete their own national ratification procedures.
