The article analyses the key factors that can have a significant impact on the dynamics of the North Atlantic Treaty Organisation(NATO) in the near future. The year 2025 has seen a remarkable transformation of the international configurationthat has developed over the past few years. This coincides with D. Trump’s second term in office, which began in February2025. The Russian-American dialogue on the normalisation of bilateral relations, which culminated in the August meetingof the two heads of state in Anchorage, has raised serious concerns among Western elites about the preservation of transatlanticunity.The possible prospects for a change in the nature of Russian-American relations have cast some doubt on the implementationof NATOʼs priority areas of activity, formulated within the framework of their new Strategic Concept in 2022, aswell as in the decisions of the allianceʼs summits in recent years.The methodology of this study is based on a systematic approach that allows consideration of the complex of factorsdetermining the development trends of the NATO, as well as key challenges to intra-bloc unity. As part of the study of theprocesses currently taking place within the framework of the alliance, both general scientific and special methods of scientificresearch were used. Among them, the comparative was used to compare the strategies of key members of the block, aswell as the structural and functional method, which made it possible to identify certain changes in the nature of intra-blockrelations. The analysis, based on the application of a set of interdisciplinary methods of humanitarian research, seems to befundamentally significant both in the context of assessing the possible prospects for the further evolution of modern internationalarchitecture, and in terms of predicting the prospects for the development of relations between the North Atlantic Blocand the Russian Federation and other key international actors.Based on the results of the study, conclusions are drawn about the emergence in 2025 of certain challenges to maintainingintra-bloc unity and further effective implementation of the strategic priorities of NATOʼs activities outlined in recentyears. The noticeable skepticism shown by D. Trumpʼs position on the current system of American obligations to ensureEuropean security, complemented by disagreements between the new US administration and a number of European alliesover a possible settlement of the Special Military Operation in Ukraine, can become a factor in a significant change in thenature of relations within the NATO.
