UN General Assembly
1966

15. Each of us has a clear duty towards mankind, towards his own country, towards world order and peace, towards the economic and social progress of the international community to do his best to help improve conditions which might prove harmful to all mankind. The interest of us all, great or small, rich or poor, is in this respect one and indivisible. We must do everything in our power to prevent erosion of the foundations of international peace which — let us never forget — are precarious and unsteady. 16. Although the matter is not on our agenda, we can hardly ignore the threat to world peace created by the Viet-Namese conflict. This conflict is the main source of the apprehension and anxiety which the present international situation has engendered. It is the most serious obstacle to the efforts made to solve other crucially important questions, such as disarmament. And it has led to the re-emergence of certain features of the cold war we had thought were for ever disposed of and abandoned.
