The Cold War officially ended more than three decades ago, but its influence continues to shape international relations.
During the second half of the 20th century, rivalry between the United States and the Soviet Union defined global politics, dividing the world into competing blocs.
Institutions such as NATO were created in this period and still play a central role in security today.
Many current tensions — including disputes over territory, military alliances and spheres of influence — can be traced back to Cold War-era decisions.
Historians note that the legacy is not only geopolitical. It also influenced technology, space exploration and economic systems.
Understanding the Cold War helps explain why certain conflicts and alliances persist in the present.
