Secretary General of NATO The Secretary General of NATO (French: Secrétaire général de l'OTAN) is an international diplomat who serves as the chief civil servant of the North Atlantic Treaty Organization (NATO). The Secretary General is responsible for coordinating the workings of the alliance, leading NATO's international staff, chairing the meetings of the North Atlantic Council and most major committees of the alliance, with the notable exception of the NATO Military Committee, and acting as NATO's spokesperson.[1] However, the Secretary General does not have any military command role, and political, military and strategic decisions ultimately rest with the member states.
