Аннотация:The article is devoted to the analysis of the Yalta system of world order as a mythological construct. The latter consists of the Soviet and Anglo-Saxon myths, which in their opposition form the mythological construct Pax Yalta. In the system of international relations, at the level of macrosocial relations, it performs the functions of the episteme of power. The construct is based on the special characteristics of space-time, which provide social trust in the various mythological elements of Pax Yalta. Namely: 1) the domination of the future over the present and the elimination of the recent past as an object of scientific or political attention; 2) the state of possession of the future and the elimination of not yet formed threats to power; 3) the discourse is carried out not by countries, not by social structures, but by individuals. However, since the 90s of the twentieth century, a systemic imbalance of the space-time constants of the Yalta world has been revealed, which leads to the prospect of the collapse of the Yalta world as a mythological construct. However, the disintegration and imbalance of the mythological construct does not mean the elimination of Pax Yalta as a fact of international relations, but only indicates a crisis of trust and the return of the construct to individual myths as such.
