The purpose of the article is to research a new stage of improving the coordination of efforts and deepening U.S.-European cooperation aimed at further strengthening transatlantic security and supporting Ukraine in the struggle for its sovereignty. The current study considers the grounds and escalation of the current Russian aggression against Ukraine; the impact of the undeclared war against Ukraine on the United States and the European community; American and European support to Ukraine, including military assistance; reasons and steps to renew the transatlantic alliance; the struggle of Ukraine for its independence and sovereignty as well as the protection of Europe and its democratic values. The methodological basis of the study is a set of general and special research methods. The system method made it possible to consider the renewal of the transatlantic alliance and the strengthening of coordination between the United States and European countries as a systemic process. In particular, the strengthening of American-European cooperation is considered as a response to the Russian-Ukrainian policy since 2014 and the escalation of armed aggression against Ukraine that is a unique state of the European geopolitical space and a powerful champion of European and universal values. Also, improving coordination between transatlantic partners is studied through the prism of comprehensive assistance to Ukraine in its struggle for sovereignty. Moreover, the prospects of strengthening mutual coordination in the transatlantic space are considered in the institutional and legal planes. The comparative method helped to analyze the volume and effectiveness of aid to Ukraine from the United States and European countries and to consider the dynamics of the renewal of the transatlantic partnership. The objective research was based on statistical methods and event data analysis, which made it possible to consider how current events in Ukraine affected the international political situation. Finally, the historical method was applied to investigate the cause-and-effect relationships of events, as well as to determine the role of Ukraine in European civilizational processes. With the help of the historical method, it has been proved that during centuries Ukraine was, is, and remains the most important structural link of European civilization. The scientific novelty consists in an attempt to comprehensively study the ongoing cooperation between the United States and European countries under the influence of the escalation of Russia’s armed aggression against Ukraine. This issue is considered through the prospect of Ukraine’s unique historical role in the defense of European civilization and general democratic values. The authors conclude that it was the armed aggression against Ukraine that contributed to the renewal of the transatlantic partnership. Currently, the United States and European partners have coordinated their efforts around assisting Ukraine and finding effective ways to restructure the transatlantic security system. It becomes obvious that Ukraine is a historically unique state on the territory of Europe, and its victory in the struggle for its sovereignty is a guarantee of a peaceful and safe future of the entire transatlantic space.

The article is devoted to the problems of racial discrimination and the anti-segregation struggle for the rights of Black citizens in American society. This problem remains relevant despite the successes of the civil rights movement and the activities of many organizations in support of the Coloured population. In this regard, the primary tasks are the following: to study the phenomenon of segregation as an instrument of racism; to identify the roots of segregation policies and the turning points in history that allowed it to be implemented; to study the evolution of the civil rights movement and to determine its achievements; to explore the phenomenon of Black Power, its impact on the consciousness of Blacks and American society in general; and to discuss the current state of American society on the subject of social justice, taking into account interethnic communication. The methodological background of the current study includes a set of general and special research methods that could be partially represented by the followings. The descriptive-historical and chronological approaches allowed to examine the outlined issues in historical retrospect and to track changes in both segregation policy and the civil rights movement. The integrated approach helped to connect different aspects of the studied problem and to link them to specific events, which made it possible to give a holistic assessment of the state of American society from the late 19th to the early 21th centuries. The research used statistical, analytical and comparative methods that were applied to analyse the situation on educational segregation and rates of living and safety of the Black population in the U.S. society. Scientific novelty involves conducting a comprehensive research based on American sources and examining the works of specialists in the field of African American studies, with the aim of their further introduction into the domestic scientific circulation. Finally, the authors conclude that despite racial segregation was not eliminated during the rise of civil rights movement, it put the new beginning for the long-term positive shifts in American society that gives hope for improving relations between Blacks and Whites and maintaining social justice for all ethnical minorities.
