Which major international body replaced the League of Nations after WWII?

• A. The United Nations Security Council (as part of the United Nations).
• B. NATO
• C. The International Court of Justice
• D. The World Trade Organization

Answer: (A)

After World War II, the international order shifted to a stronger, more enforceable system for preventing war and handling disputes, culminating in the creation of the United Nations in 1945. Within that framework, the Security Council became the central body responsible for maintaining international peace and security. It has the authority to authorize actions like peacekeeping missions, sanctions, or collective security measures, with major powers holding veto power to ensure major consensus. This makes it the best answer because it represents the new, binding structure that succeeded the League of Nations in guiding how nations cooperate to prevent aggression. The other options don’t fit: NATO is a regional defense alliance formed later, not a replacement for the League; the International Court of Justice is a UN organ that handles disputes but is not the replacement mechanism for postwar security; the World Trade Organization focuses on trade rules and came well after the war, not on security.
