The subject analyzed in the article is the basic components of Z.Brzezinski’s concept of the world politics. As is demonstrated by the author, it is not only the images of the USA and of the USSR that played the key role in the said concept, but also the image of the world politics as foreign policy interactions’ medium possessing its own independent properties. According to the author’s conclusion, under the conditions of the 1970s to the early 1980s it was not impending Soviet hegemony that Brzezinski regarded as the greatest menace, which hegemony he considered unachievable, but impending deepening of general “unpredictability”, “uncertainty” and “chaos”, fraught with destruction of world order and transition to “war of all against all”.
