Several serious circumstances led to the writing of this essay: since 2008 the crisis remains, albeit with varying degrees of intensity, the situation in the field of international security, as well as debt and institutional crises, are worsening not only in the eurozone. Probably the organized migratory wave of war, economic and climate migrants continues to move across the permeable borders of the Schengen area, showing how the European Union is fragile and helpless. [Klaus, Weigl, 2015] German Chancellor Angela Merkel said there is no upper limit for the number of people who would be admitted to escape political persecution in their country. Germany leaves the Dublin system inconsistently, runs counter to European cohesion and stops differentiating between the immigrant and the refugee. Migration divides EU Member States into patriarchal and patrimonial and distrust between municipalities. Between „old” and „new” EU countries, scissors are opened. In addition, in some regions of Europe (France, Belgium, Germany, Sweden, the United Kingdom) there are closed communities where the majority law is not valid. Our current socio-political and economic existence is based on a traditional understanding of security. However, the second decade of the 21st century represents a political and military conservative mirror that reflects the image of prosperity and security from a different angle than in previous years. Dramatic developments have led to massive migration of the peoples of the African and Asian continent and to the division of the European Union, especially with regard to the permanent mechanism of redistribution of asylum seekers. Our aim is to contribute to discussion and reflection on topical issues of security environment and security system as a follow-up to the dramatic development that have resulted in the massive migration of people from the African and Asian continent, and in the European Union's break-up, especially in view of the permanent mechanism of redistribution of asylum seekers. We are focused on to what extent the security system of the EU and national states has been threatened and what the threatening factors are. Our aim is to point out that the international security situation has not changed for the better in the second decade of the 21st century. For this purpose, the author uses deductive, analytical, comparative, scientific methods such as exploration, prediction, explanation, and Hanlon's razor.
