Declaration approved and published by the North Alantic Council in Ministerial Session in Ottawa on 19 June, 1974 and signed by Heads of NATO Government in Brussels on 26 June.

1. The members of the North Atlantic Alliance declare that the Treaty signed 25 years ago to protect their freedom and independence has confirmed their common destiny. Under the shield of the Treaty, the Allies have maintained their security, permitting them to preserve the values which are the heritage of their civilisation and enabling Western Europe to rebuild from its ruins and lay the foundations of its unity.
2. The members of the Alliance reaffirm their conviction that the North Atlantic Treaty provides the indispensable basis for their security, thus making possible the pursuit of détente. They welcome the progress that has been achieved on the road towards détente and harmony among nations, and the fact that a conference of 35 countries of Europe and North America is now seeking to lay down guidelines designed to increase security and cooperation in Europe. They believe that until circumstances permit the introduction of general, complete and controlled disarmament, which alone could provide genuine security for all, the ties uniting them must be maintained. The Allies share a common desire to reduce the burden of arms expenditure on their peoples. But states that wish to preserve peace have never achieved this aim by neglecting their own security.
3. The members of the Alliance reaffirm that their common defence is one and indivisible. An attack on one or more of them in the area of application of the Treaty shall be considered an attack against them all. The common aim is to prevent any attempt by a foreign power to threaten the independence or integrity of a member of the Alliance. Such an attempt would not only put in jeopardy the security of all members of the Alliance but also threaten the foundations of world peace.
4. At the same time they realise that the circumstances affecting their common defence have profoundly changed in the last ten years: the strategic relationship between the United States and the Soviet Union has reached a point of near equilibrium.
   Consequently, although all the countries of the Alliance remain vulnerable to attack, the nature of the danger to which they are exposed has changed. The Alliance's problems in the defence of Europe have thus assumed a different and more distinct character.
5. However, the essential elements in the situation which gave rise to the Treaty have not changed. While the commitment of all the Allies to the common defence reduces the risk of external aggression, the contribution to the security of the entire Alliance provided by the nuclear forces of the United States based in the United States as well as in Europe and by the presence of North American forces in Europe remains indispensable.
6. Nevertheless, the Alliance must pay careful attention to the dangers to which it is exposed in the European region, and must adopt all measures necessary to avert them. The European members who provide three-quarters of the conventional strength of the Alliance in Europe, and two of whom possess nuclear forces capable of playing a deterrent role of their own contributing to the overall strengthening of the deterrence of the Alliance, undertake to make the necessary contribution to maintain the common defence at a level capable of deterring and if necessary repelling all actions directed against the independence and territorial integrity of the members of the Alliance.
7. The United States, for its part, reaffirms its determination not to accept any situation which would expose its Allies to external political or military pressure likely to deprive them of their freedom, and states its resolve, together with its Allies, to maintain forces in Europe at the level required to sustain the credibility of the strategy of deterrence and to maintain the capacity to defend the North Atlantic area should deterrence fail.
8. In this connection the member states of the Alliance affirm that as the ultimate purpose of any defence policy is to deny to a potential adversary the objectives he seeks to attain through an armed conflict, all necessary forces would be used for this purpose. Therefore, while reaffirming that a major aim of their policies is to seek agreements that will reduce the risk of war, they also state that such agreements will not limit their freedom to use all forces at their disposal for the common defence in case of attack. Indeed, they are convinced that their determination to do so continues to be the best assurance that war in all its forms will be prevented.
9. All members of the Alliance agree that the continued presence of Canadian and substantial US forces in Europe plays an irreplaceable role in the defence of North America as well as of Europe. Similarly the substantial forces of the European Allies serve to defend Europe and North America as well. It is also recognised that the further progress towards unity, which the member states of the European Community are determined to make, should in due course have a beneficial effect on the contribution to the common defence of the Alliance of those of them who belong to it. Moreover, the contributions made by members of the Alliance to the preservation of international security and world peace are recognised to be of great importance.
10. The members of the Alliance consider that the will to combine their efforts to ensure their common defence obliges them to maintain and improve the efficiency of their forces and that each should undertake, according to the role that it has assumed in the structure of the Alliance, its proper share of the burden of maintaining the security of all. Conversely, they take the view that in the course of current or future negotiations nothing must be accepted which could diminish this security.
11. The Allies are convinced that the fulfillment of their common aims requires the maintenance of close consultation, cooperation and mutual trust, thus fostering the conditions necessary for defence and favorable for détente, which are complementary. In the spirit of the friendship, equality and solidarity which characterise their relationships, they are firmly resolved to keep each other fully informed and to strengthen the practice of frank and timely consultations by all means which may be appropriate on matters relating to their common interests as members of the Alliance, bearing in mind that these interests can be affected by events in other areas of the world. They wish also to ensure that their essential security relationship is supported by harmonious political and economic relations. ln particular they will work to remove sources of conflict between their economic policies and to encourage economic cooperation with one another.
12. They recall that they have proclaimed their dedication to the principles of democracy, respect for human rights, justice and social progress, which are the fruits of their shared spiritual heritage and they declare their intention to develop and deepen the application of these principles in their countries. Since these principles, by their very nature, forbid any recourse to methods incompatible with the promotion of world peace, they reaffirm that the efforts which they make to preserve their independence, to maintain their security and to improve the living standards of their peoples exclude all forms of aggression against anyone, are not directed against any other country, and are designed to bring about the general improvement of international relations. In Europe, their objective continues to be the pursuit of understanding and cooperation with every European country. In the world at large, each Allied country recognises the duty to help the developing countries. It is in the interest of all that every country benefit from technical and economic progress in an open and equitable world system.
13. They recognise that the cohesion of the Alliance has found expression not only in cooperation among their governments, but also in the free exchange of views among the elected representatives of the peoples of the Alliance. Accordingly, they declare their support for the strengthening of links among Parliamentarians.
14. The members of the Alliance rededicate themselves to the aims and ideals of the North Atlantic Treaty during this year of the twenty-fifth anniversary of its signature. The member nations look to the future, confident that the vitality and creativity of their peoples are commensurate with the challenges which confront them. They declare their conviction that the North Atlantic Alliance continues to serve as an essential element in the lasting structure of peace they are determined to build.
