In the modern world, almost simultaneously in the texts on national security strategies of the United States and the European Union the weak states are mentioned as the main threat to security for the whole world. The relevance of the study lies in the fact that it covers the search for solutions to problems in several areas, including the post-Soviet transfer, the issues of the African continent development and formation, the study of security issues in the Middle East. In this book attempts to identify discrepancies in definitions and categorizations, as well as to analyze the preconditions and ways to overcome the position of "weak state", in particular in the foreign economic and security sector. The threats to international security of countries with a "weak state" status have been summarized. Within this research, it has first been proposed to clarify the definitions of "weak" and "failed" states, as well as to determine the principles of the weak state existence along withthe neighboring large country, and clearly defined preconditions and ways of overcoming its political and economic weakness, on the example of Ukraine.
