The last century was tense and also varied in its events, in this century two world wars took place, a term such as superpower emerged, military tensions and armed conflicts were on all continents of the world, be it two or more state confrontations or civil wars in any country. The epicenter of the events was in Europe.
Due to the escalation of events, various organizations, military blocs or other agreements have been established between the states, such a large world organization as the UN, the European Union and the largest and most powerful military bloc in the future, such as NATO. The reason for the creation of NATO was clear to everyone then and now, its main purpose was to defend itself from the threat posed by the Soviet Union.
The events after the collapse of the Soviet Union changed and the existence of Nao was also questioned, but as the situation shown, NATO reorganized due to the current situation and became involved in various issues, while Russia, the successor to the Soviet Union, was already strengthened.
In this paper we discuss the reasons for the creation of NATO, its functions and its development. We will cover topics such as the role of NATO during the Cold War, its aftermath, and NATO's fight against terrorism.
Such a development had a profound effect on the geopolitics of the world at the time, with the creation of this organization playing a major role in redistributing the balance of power across the continent, splitting in two the world that once fought its enemy together.
