NATO – From 1949 to Today: Expansion, Defense, and Modern Challenges

In this video, we explore the origins, evolution, and global impact of the North Atlantic Treaty Organization (NATO). From its founding in 1949 with 12 nations to its current membership of 32, NATO has adapted to new threats—from the Cold War to terrorism, cyberattacks, and rising tensions with Russia.
We break down:
• The complete timeline of NATO's expansions
• The only time Article 5 was invoked (after 9/11)
• NATO’s combat missions in Afghanistan and training roles in Iraq
• The recent additions of Finland and Sweden
• Why Russia’s aggression is raising new alarms inside the alliance
Includes an animated map showing each country’s entry into NATO over time.
Watch now to understand how NATO’s promise of collective defense continues to shape global security.
