The narrative 'sweeps through' history, starting with the Treaties of Westphalia in 1648, on to the Congress of Vienna of 1814-15, to the current terminology of 'modern multilateralism' with its lineage from the Versailles Treaty of 1919 and the League of Nations, to the United Nations Monetary and Financial Conference at Bretton Woods in 1944, the European Coal and Steel Community of 1950, to the Nuclear Non-Proliferation Treaty (NPT) of 1970 and concluding the sweep with the Helsinki Process culminating in 1975. The objective of the 'sweep through history' and its main thrust is to analyze how at different times, the world powers of the day turned to multilateralism only after some prolonged, devastating conflict that they had had either blundered, or charged into, left them with no choice, but to sit down and talk, negotiate and take into account a balance of the interests of all parties. All these build up to a point where the narrative explores today's challenges and 'attacks' on multilateralism and the seeming inability of the international community to reengage and work together, to stem, in the words of the United Nations Secretary-General "the wind of madness sweeping the globe." The article makes the case, essentially, for the obvious: we are on the verge of blundering into something far more devastating than the world has experienced before for a variety of reasons, not least among them, unusually deteriorated relations among the most heavily armed and powerful States, a climate catastrophe that is already at our doorstep, the dark side of the unprecedented, quantum leaps in technological development, the deficit of trust among peoples, countries, communities and societies. Add to that the 'game-changing' COVID-19 pandemic and what the world has before it, is a stage set for planetary calamity. We should pull back from the precipice in time. Multilateralism, modern multilateralism, which marks its 100th anniversary this year, is the only way to do this. [ABSTRACT FROM AUTHOR]
