In the rubble of World War II, a powerful alliance was formed to prevent future conflict-NATO. Created to unite democratic nations against the threat of Soviet expansion, it quickly became a cornerstone of global defense.

Trace the rise, reach, and resilience of one of the most influential alliances in modern history.
