The Birth of the United Nations – Idealism vs. Realism 🌍

Headline: Why did the League of Nations fail? The Yalta Conference & The UN Charter Explained.

Overview:
In this first part of our UN Comprehensive Series, we break down the transition from the failed League of Nations (1920) to the robust United Nations (1945). If you are a Political Science student or preparing for competitive exams like UGC NET, CUET PG, or UPSC, this video covers the crucial shift in "Global Governance" history.

What you will learn in 60 seconds:

The Failure of Idealism: How Woodrow Wilson’s 14 Points created a League that lacked the "teeth" (military power) and the support of major powers like the USA.

The Yalta Shift (Feb 1945): Why the 'Big Three'—Roosevelt, Churchill, and Stalin—decided that peace requires Realpolitik and the involvement of great powers.

The Collective Security Model: How the UN Charter (Oct 24, 1945) moved beyond just talking and created a system of 'Principal Organs' and 'Veto Power' to ensure a Third World War never happens.
