NATO enlargement policy

NATO enlargement refers to the process of adding new member countries to the North Atlantic Treaty Organization, a military alliance established for collective defense. This policy aims to enhance security in Europe by integrating nations that share democratic values and a commitment to stability. Countries seeking membership must meet specific political, military, and economic criteria. NATO enlargement is intended to deter aggression, promote peace, and strengthen cooperation among allies, especially in response to geopolitical tensions. Notable enlargements occurred after the Cold War, with several Eastern European nations joining to reinforce regional security.
