Abstract: The subject of the study is the historical conditions in which the disloyal attitude of the Visegrad Group towards the solutions proposed by the EU began to grow during the specified period of time.
The analysis of the migration crisis, which has aggravated political, economic, financial, social, and religious problems in the EU countries, is carried out. The EU's efforts to overcome it have become the basis for strengthening the role of right-wing parties in the Quartet.
The role of Hungary, which represents itself as a defender of "Europe as a continent for Europeans", which has pursued the most active restrictive migration policy, is considered.
The plans of the leadership of Germany and Austria for the management of migration flows, reflecting the ambitions of Berlin and Vienna for the transit and reception of refugees, are presented.
The "central" line of Brussels on overcoming the migration crisis is being studied.
The tools used by V4 to overcome the migration crisis caused by the vulnerability of the Quartet countries to refugee flows are considered.
The article also examines criticism from the "quartet" of the process of overcoming the migration crisis, which saw in the measures proposed by Brussels a threat to the national identity of its small states and a sign of disrespect for the interests of small states in the EU.

    In general, the migration crisis has resulted in the strengthening of far-right parties in Hungary and Poland, the radicalization of public opinion, which contradicts the main goals of European integration. Thus, the internal political development in some countries of the "Visegrad Four" has actually become a new noticeable element of confrontation with the European Union. Hungary and Poland reacted extremely painfully to criticism of the EU, appealing for support to partners in the Visegrad Group, to other countries where right-wing and conservative parties are also popular (Italy, Austria). As a counteraction, the EU leadership raised the issue of a threat to EU values in Poland and Hungary and considered the possibility of using a mechanism to influence countries that do not respect the values of the European Union.

Abstract: The subject of the study is the impact of the Ukrainian crisis on foreign and defense policy V4. The statements and actions of the Visegrad Group on the Ukrainian issue, which were ahead of the European Union's activity in their efficiency, are being investigated. However, the consolidation of the "quartet" countries has already been seriously tested in the first months and even weeks of the crisis, which will subsequently allow us to talk about the existence of a significant split between the participants. In addition, V4's activities regarding the Ukrainian crisis were mostly in the nature of a reaction to the events taking place, which did not offer any constructive strategies for resolving the process. The novelty of the scientific research in the framework of this article is expressed in the analysis of normative legal acts, statements of the Visegrad Group, demonstrating the different degree of response of V4 to various stages of the Ukrainian crisis, as well as the change in approaches to the defense policy of the "quartet" countries in the specified period of time. Also, the previously unexplored Action Plan of the Visegrad Group Defense Cooperation will be presented in the 2020 edition, which will indicate a wide range of challenges and threats, some of which do not directly relate to the security of the "quartet" countries, which indicates the actual disappearance of a purely regional component in the defense policy of the Visegrad Group.

Abstract: The subject of the study is the historical conditions in which the process of designing and implementing the Eastern Partnership program began, which became the only significant foreign policy initiative of the Visegrad Four. The role of Poland, which positioned itself as a link between the EU and part of the post-Soviet space, is considered. The plans of France, Bulgaria and Romania in 2003-2004 for a number of post-Soviet countries, reflecting the ambitions of Paris, Sofia and Bucharest in the Black Sea and Mediterranean region, are presented. But under pressure from the European Commission, these initiatives were not further developed, and a decision was made to implement the Eastern Partnership project.
The development tools used by V4 for the implementation of the Eastern Partnership project, due to the limited resource base of the Quartet countries, are considered. The criticism of the Eastern Partnership project is being studied, due to the lack of a common understanding among EU members of what prospects the new project can offer to "partner countries".
The novelty of the scientific research in the framework of this article is expressed in the analysis of the "energy crises" and the change in the EU's approaches to the post-Soviet space in the late 2000s, which became the basis for the development and implementation by the Visegrad Group in 2004-2014 of the Eastern Partnership program. In this program, the "four" countries played the role of curators and a link between the EU and the post-Soviet space. The implementation of the project allowed V4 to gain political weight within the European Union. When developing relations with the "partner countries", the Visegrad Group tried to make maximum use of all available mechanisms and tools (for example, the potential and experience of implementing joint projects within the framework of the International Visegrad Foundation). At the same time, our own capabilities and resources (coupled with the ambiguous perception of the Eastern Partnership in the EU) did not allow us to fully implement all the stated strategic goals, which seriously affected the effectiveness of the project and the results obtained.
