Great Decisions High School: NATO

NATO, the North Atlantic Treaty Organization, was founded in 1949 to provide collective defense against Soviet aggression. Over the years, it has expanded from 12 to 31 member nations, adapting to new global threats such as terrorism, cyberattacks, and regional conflicts. The Russian invasion of Ukraine in 2022 has revitalized NATO’s role, prompting debates on its relevance, expansion, and the responsibilities of its members. This edition examines NATO’s history, purpose, military commitments, and the challenges it faces in an era of shifting global power dynamics.


Key Topics Covered:

  • The History & Purpose of NATO – Formed during the Cold War, NATO was designed to counter Soviet influence in Europe.
  • Article 5 & Collective Defense – The principle that an attack on one member is an attack on all, invoked only once after 9/11.
  • NATO’s Expansion & Russia’s Reaction – Countries like Poland, Latvia, and Finland joined for security, but Russia sees NATO’s growth as a threat.
  • The U.S. Role & Funding Debates – Should the U.S. continue paying a significant portion of NATO’s defense budget?
  • The Ukraine War & NATO’s Future – The largest European war since WWII has tested NATO’s unity and sparked discussions on whether Ukraine should be admitted.
  • The Debate Over NATO’s Relevance – Is NATO still necessary, or should European nations take responsibility for their own defense?
