INTRODUCTION. This year is the 75-th anniversary of the Great Victory of the Allies – Britain, the Soviet Union and the USA – over Nazi Germany. The most important legal result of this victory has become the Charter of the United Nations – the universal treaty initiated by Great Britain, the Soviet Union and the USA (and later – by China and France) aiming to save succeeding generations from the new world war by establishing United Nations mechanisms to maintain international peace and global security. The UN Charter has since become the foundation of modern international law, respected by States across continents and generations. That seems, however, to begin changing after the collapse of the Warsaw Pact, when its former-members «socialist» European countries (including Bulgaria and Poland) became a part of the Western military bloc – North Atlantic Treaty Organization (NATO). NATO seems to demonstrate now a new attitude to fundamental principles of the UN Charter, first of all, to the principle relating to the use of armed force only according to the UN Charter. NATO States-members launched in 1999 an air campaign against Serbia without authorization by the Security Council; then an ad hoc western coalition, led by the United States, resorted to armed force in 2003 against Iraq and organized in the occupied territory of Iraq the death penalty of the President Saddam Hussein. Even some western European States, France and Germany, first of all opposed such military action of the USA for ignoring the UN Charter. The apparent involvement of the USA in the unconstitutional removal of the Ukrainian President Yanukovich from power in Kiev in 2014 and the subsequent local war between those who recognize such a discharge as legitimate and those who do not (both referring to the right of self-defense) – these facts make the problem of international peace especially urgent. In this political environment, the risks of World War III seem to be increasing. This paper addresses such challenges to modern international law.MATERIALS AND METHODS. Th background of this research is represented by the teachings of distinguished scholars and other specialists in international law, as well as international materials including documents of the international conferences relevant to the topic. Some of such materials are alarming, noting that the international legal system is in danger of collapse and it is doubtful whether an international legal order will be possible in the coming decades at all. Others are not so pessimistic. The analytical framework includes also suggested interpretations of the UN Charter and other international treaties regulating interstate relations in the area of global security. The research is based on a number of methods such as comparative law and history of international law, formal logic, including synthesis of relevant facts and analogy.RESEARCH RESULTS. It is acknowledged that there is a need for a more coherent international legal order, with the system of international law being at its heart. Within the context of applicable principles and norms of international law, this article specifically provides the results of analysis of the following issues:1) centrifugal interpretations of international law as they are reflected in its sources; 2) the need for increasing the role of the UN Charter in the global international legal framework; 3) modern values of the UN Charter as an anti-confusion instrument; 4) the contemporary meaning of the Principles embedded in the UN Charter; 5) comparison of the main principles of international law and general principles of law; 6) jus cogens and the UN Charter.DISCUSSION AND CONCLUSIONS. After discussing the issues noted above, this paper concludes that it is in the interest of the community of states as a whole to clarify the normative structure and hierarchy of modern international law. Greater discipline will need to be demonstrated in the use and classification of principles of international law and general principles of law in the meaning of Article 38 of the ICJ Statute. The content of jus cogens norms most probably will be gradually identified, after diffi lt discussions across the international community, both at interstate level and among academics. At the heart of such discussions may be the conclusion suggested in this paper on the peremptoriness of the principles of the United Nations Charter – Articles 1 and 2. Such an approach will further promote international law at the advanced quality of regulation of international relations and, for the good of all mankind, assist in the establishment of an international environment much more dependent on the rule of law.
