Important for GS Prelims: (International Relations )
Context:
NATO’s continuous enlargement and its post-Cold War strategic shift from mere collective defense to global collective security make it a highly probable topic for Prelims.
1. About NATO
- Formation: April 4, 1949 (Washington Treaty), drawing authority from Article 51 of the UN Charter (right to collective defense).
- Headquarters: Brussels, Belgium. (Allied Command Operations is near Mons, Belgium).
- Membership: Expanded from 12 founding members to 31 countries (Finland is the latest, joining in 2023).
- Decision Making: Operates strictly on consensus. Any single member can veto a new applicant.
2. Crucial Articles
- Article 5 (Collective Defence): An attack on one member is an attack on all. It has been invoked only once (following the 9/11 attacks on the US). Direct military intervention is not mandatory; members respond as they deem fit.
- Article 10 (Open Door Policy): Membership is open exclusively to European countries, subject to unanimous approval.
3. Key Fact
- EU Member but NOT in NATO: Austria.
- NATO Member but NOT in EU: United Kingdom.
- Neither EU nor NATO: Switzerland, Moldova, and Belarus.
- Aspirants: Bosnia and Herzegovina, Georgia, Sweden, and Ukraine.
4. Associated Groupings
- Warsaw Pact (1955–1991): A Soviet-led treaty created to counter NATO. Prelims Catch: All of its non-Russian former member states are now part of NATO.
- CSTO (1992): The Collective Security Treaty Organization led by Russia. (Current Members: Russia, Kazakhstan, Kyrgyzstan, Tajikistan, Armenia, Belarus).
- NATO Plus: A strategic defense cooperation grouping of NATO and five aligned nations (Australia, New Zealand, Japan, Israel, and South Korea).
Conclusion:
Originally formed as a deterrent against the USSR, NATO has survived the Cold War’s end, remaining a cost-effective European security umbrella and an avenue for US global power projection.
