This research paper focused on the core elements of NATO by employing a secondary qualitative approach to data collection. NATO’s establishment in 1949 as a security defense organization against Soviet threats, its enlargement policies during the Cold War, its post-Cold War reformation and enlargement process, the roles it played following the 9/11 incident, and its increasing role and influence in the global community in the 21st century were reviewed. The role and influence of the United States right from NATO’s establishment until this present day as well as its hostility with the Soviet Union during the Cold War period and its post-Cold War rivalry with Russia were also discussed. The outcome of the study shows that NATO’s enlargement policy has been the major issue faced by the alliance in its seven decades of existence. NATO’s objectives have revolved around enlargement since the Cold War period which saw the alliance face hostility from the Soviet Union, and its further expansion objectives during the post-Cold War have been met with further adversity from Russia who has and continues to vehemently oppose the alliance’s expansion plans into Eastern Europe. The issue of enlargement has generated several social, economic, military, nuclear, and political crises over the years and this has been challenging for the alliance. Nevertheless, NATO’s expansion policy has been of immense significance and contributed to European stability and ensuring a cooperative transatlantic relationship. NATO’s enlargement policy has also helped resolve instability and political conflicts in Eastern and Central Europe by annexing the former Soviet-bloc states and fostering cooperation across Europe. NATO has also been involved in several key intervention programs which have yielded mixed results, some successful and others critiqued. Notably, in all the seven decades of NATO’s existence, it has operated under the wings of the United States, and despite the alliance being the longest international organization and the only international body to have outlived the Cold War era, several pertinent questions have been raised about the alliance being an instrument of the United States regardless of the success of the USA-NATO relationship. The research concludes by proffering viable solutions which could enhance and strengthen NATO’s dominance as the world’s most effective international organization.
