The North Atlantic Treaty Organization (NATO) is significant in global politics as a military alliance that promotes collective defense among its member states. Formed in 1949, NATO's primary goal is to ensure the security and stability of its members against external threats, particularly during the Cold War. In contemporary politics, NATO remains a key player in addressing challenges such as terrorism, cyber threats, and geopolitical tensions. Furthermore, its collaborative nature fosters military and political cooperation among allied nations, influencing international relations and security policies. NATO's relevance underscores the importance of alliances in maintaining peace and security worldwide.
