Modern System of International Relations and Role of the USA

Abstract

Abstract
The whole twentieth century and the beginning of the 21st century has been unique in modern history; for three centuries the structure of
international politics remained multipolar, in the twentieth century it has changed three times. Multipolar at the outset, it became bipolar after the
Second World War, unipolar with the disintegration of the Soviet Union, and as the new millennium dawns it is gradually becoming multipolar once
more. In this regard, by the presenting of the comparative analysis of the different international systems in the world, it is important to determine
the role and place of the USA within the modern international system.
