UN, NATO, BRICS, G21, and G7: Roles, Differences, and Relevance in Today’s World

Introduction: Why These Global Bodies Matter More Than Ever

The world today is deeply interconnected—what happens in one corner of the globe often impacts people thousands of miles away. Whether it’s a war, an economic crash, a pandemic, or climate change, no single country can tackle these issues alone. That’s where global organizations come in.

From the peacekeeping missions of the United Nations to the economic clout of G21, and from the strategic muscle of NATO to the emerging alliance of BRICS, these global groups play vital roles. But how are they different? Why are some more talked about than others? And which ones are still relevant in 2024?

Let’s explore these five major global platforms—UN, NATO, BRICS, G21, and G7—in simple terms that anyone can understand. We’ll also look at specific global events where these bodies have played a crucial role. Perfect for competitive exam aspirants, policy enthusiasts, and knowledge seekers!
