NATO Membership – Accession Process

Steps to Join NATO

Ratification by NATO Member States
- The governments of NATO member states ratify the protocols, according to their national requirements and procedures.
Formal Invitation
- Once all NATO member countries notify the Government of the United States of America, the depository of the Washington Treaty, of their acceptance of the protocols to the North Atlantic Treaty on the accession of the potential new members, the Secretary General invites the new countries to accede to the Treaty.
Deposition of Instrument of Accession
- Applicant deposits the document with the US State Department (as treaty depository).
- Membership becomes official.

Funding

NATO is resourced through the direct and indirect contributions of its members.

Nato Funding in detail

National (or indirect) contributions are the largest component of NATO funding and are borne by individual member countries. These include the forces and capabilities held by each member country, which can be provided to NATO for deterrence and defence activities and military operations.
Direct contributions finance NATO’s budgets, programmes and capabilities in support of objectives, priorities and activities that serve the interests of the Alliance as a whole – and cannot reasonably be borne by any single member – such as Alliance operations and missions or NATO-wide air defence or command and control systems.
All Allies contribute to funding NATO using an agreed cost share formula derived from the Gross National Income of member countries. This is the principle of common funding and it demonstrates burden-sharing in action.

Governance Structure

North Atlantic Council (NAC): Main decision-making body.

The North Atlantic Council is the principal political decision-making body within NATO.
It oversees the political and military process relating to security issues affecting the whole Alliance.
It brings together representatives of each member country to discuss policy or operational questions requiring collective decisions, providing a forum for wide-ranging consultation between members on all issues affecting their peace and security.
Policies decided in the NAC are the expression of the collective will of all member countries of the Alliance since decisions are made on the basis of unanimity and common accord.
The Secretary General chairs the NAC and its decisions have the same status and validity at whatever level it meets.
It was the only body established by the North Atlantic Treaty (Article 9) in 1949 and the only one with the authority to set up subsidiary bodies.

Secretary General: Chief administrative officer.

The Secretary General is the Alliance’s top international civil servant.
This person is responsible for steering the process of consultation and decision-making in the Alliance and ensuring that decisions are implemented.

Military Committee: Provides strategic advice.

The Military Committee (MC) is the senior military authority in NATO and the oldest permanent body in NATO after the North Atlantic Council, both having been formed only months after the Alliance came into being.
The Committee’s principal role is to provide consensus-based advice on military policy and strategy to the North Atlantic Council and direction to NATO’s Strategic Commanders.
The Military Committee is made up of senior military officers (usually three-star Generals or Admirals) from NATO member countries, who serve as their country’s Military Representative (MILREP) to NATO, representing their Chief of Defence (CHOD).

Allied Command Operations (ACO): Oversees military operations.

Allied Command Operations (ACO) is responsible for the planning and execution of all Alliance operations.
It consists of a small number of permanently established headquarters, each with a specific role.
The command’s overall aim is to contribute to Allied defence and security by maintaining the integrity of Alliance territory, safeguarding freedom of the seas and economic lifelines, and to preserve or restore the security of its members.
Allied Command Operations is one of two Strategic Commands at the head of NATO’s military command structure. The other is Allied Command Transformation, which is responsible for ensuring NATO’s military structure and capabilities remain relevant, capable and credible in a rapidly changing world.
ACO consists of a number of permanently established headquarters operating at the strategic, operational and tactical levels; they are augmented by national forces assigned to NATO for specific standing and/or crisis roles and tasks.

The Nuclear Planning Group

It acts as the senior body on nuclear matters in the Alliance and discusses specific policy issues associated with nuclear forces.
The Nuclear Planning Group (NPG) reviews and sets the Alliance’s nuclear policy in light of the ever-changing security environment.
The Nuclear Planning Group has comparable authority to the NAC, but only for matters within its specific area of competence, i.e., nuclear policies, planning and consultation procedures.

Decision Making

A “NATO decision” is the expression of the collective will of all 32 member countries since all decisions are taken by consensus.
