major achievements of NATO

1. Preventing Major War in Europe (Cold War Deterrence)

One of NATO’s biggest achievements was deterring conflict between Western Europe and the Soviet bloc during the Cold War (1949–1991).

• NATO’s principle of collective defense—Article 5—meant an attack on one member would trigger a response from all.

• This created a strong military balance against the Warsaw Pact.

• Many historians argue NATO helped prevent a large-scale war in Europe during decades of intense geopolitical rivalry.
