The United Nations — Structure, Bodies & Functions

The United Nations exists because the League of Nations failed. This isn't cynicism—it's the foundational fact you must understand. In 1920, the League of Nations was created to prevent another World War. It failed catastrophically. World War II happened anyway. When the smoke cleared in 1945, the world's surviving superpowers decided to try again, differently. The UN is the result: born not from idealism, but from trauma.

Why the UN Was Created: The League of Nations Disaster

The League of Nations, established in 1920 after World War I, had three fatal flaws:

1. The United States never joined. Even though US President Woodrow Wilson championed the League, the US Congress rejected it. A global peace organisation without the world's strongest nation? Toothless.

2. It had no enforcement mechanism. The League could condemn, discuss, and pass resolutions, but when Japan invaded Manchuria (1931) or Italy invaded Abyssinia (1935), the League issued statements. Nothing more. Nations ignored it.

3. Major powers walked out when inconvenient. Germany and Japan left the League when they wanted to expand militarily. Without enforcement, there were no consequences.

Result: The League couldn't stop World War II. By 1939, it was irrelevant. By 1945, it was dissolved.

[Memory Hook] League = "No teeth." UN = "Teeth with veto limits (P5 can block enforcement)." The UN was designed to learn from the League's failures, which is why it has a Security Council with enforcement power—but even that's limited by the veto.

The San Francisco Conference & UN Charter (1945)

In April 1945, even before Germany surrendered, the victorious nations met in San Francisco to draft the UN Charter. The "Big Three" (USA, USSR, UK) drove the negotiations. China and France also participated as major powers. The Charter was signed on June 26, 1945, and the UN officially came into existence on October 24, 1945—now celebrated annually as UN Day.

[Exam Trap] Students often write "1945" without clarifying: April = Charter drafted, June 26 = Charter signed, October 24 = UN comes into existence. Exams typically test "1945" as the answer, but knowing June 26 and October 24 shows deeper mastery.

The Charter established a fundamental principle: the UN would be open to all peace-loving nations. This is why India joined on October 30, 1945—just 6 days after the UN's official inception, even though India was still under British colonial rule. India was represented by Sir Arcot Ramasamy Mudaliar, and this early membership shaped India's role in UN history.

UN Membership: How Many Nations?

As of 2026, the UN has 193 member states. To join, a nation must:

• Apply through the UN Security Council
• Win Security Council recommendation (requiring 9 out of 15 affirmative votes)
• Win General Assembly approval (requiring 2/3 majority)
• Be a peace-loving state willing to uphold the Charter

[Memory Hook] 193 = "Nearly all nations on Earth." To put this in perspective, there are roughly 195 sovereign nations globally, and 193 are in the UN. Only two notable non-members: Vatican City (observer state) and Palestine (observer state, but not full member due to geopolitical blocking).

India's membership is noteworthy because it joined as an independent nation before independence was formally declared. In 1945, India was the British Raj, represented as "India" at the UN by an Indian delegation led by Dr. Radhakrishnan and others. This gave India a voice in shaping the post-WWII order.

The UN Structure: Four Main Bodies

The UN is vast and confusing. To keep it simple, remember: four main bodies, each with different power levels.

1. The General Assembly (GA)

Founding Year: 1945 (Part of the original UN Charter)

Composition: All 193 member states; each sends a delegation led by their Foreign Minister or a permanent representative.

How It Works:

• Every nation gets exactly one vote, regardless of size or power
• Resolutions require a simple majority (50% + 1) to pass (General matters), or 2/3 supermajority for important matters (peace & security, membership, budget)
• The GA elects its President annually (a ceremonial role)

Power Level: Soft power. The GA can discuss, condemn, and recommend. Resolutions are typically non-binding. Think of the GA as a global student council where every country gets to speak, but no one can force anyone to act.

[Memory Hook] General Assembly = "Talk shop." Every nation gets to be heard, even tiny nations like Mauritius or Fiji. This is why the GA is often packed with 2-3 hour speeches and dramatic debates. Power? Not much. Drama? Maximum.

India's Role: India is the 5th largest group leader in the GA (often leading the Non-Aligned Movement bloc of ~120 nations). India's votes have shaped resolutions on colonialism, nuclear disarmament, and climate change. However, India has no special veto power in the GA like the P5 do in the Security Council.

2. The Security Council (UNSC)

Founding Year: 1945

Composition: 15 members total:

• 5 Permanent Members (P5) with veto power: USA, United Kingdom, Russia (USSR until 1991), France, China
• 10 Non-Permanent Members elected for 2-year terms

How It Works:

• Each member gets one vote
• A resolution needs 9 affirmative votes to pass
• Any P5 member can veto a resolution, killing it instantly
• Non-permanent members are elected by the GA and cannot veto

Power Level: Hard power. The Security Council has enforcement authority. Under Chapter VII of the UN Charter, the UNSC can authorize military action, impose sanctions, and mandate international interventions. This is why the UNSC is the real seat of UN power.

Veto Power: This is the most controversial feature. The veto was a compromise to keep the USSR (and later Russia) in the UN after WWII. The theory: if the superpowers felt threatened, they could block UNSC action, preventing the organisation from taking sides against them. In practice, the veto has been abused. Russia and China have vetoed numerous resolutions on Syria, Myanmar, and other conflicts, preventing military interventions. The USA has used its veto to protect Israel and other allies. France and UK rarely veto but have the power to do so.

[Exam Trap] Students often assume the UNSC has 5 permanent members who can always control everything. Not quite. A veto can stop enforcement, but 9 votes are needed to pass a resolution in the first place. So if only 4 P5 members and 4 non-permanent members vote for a resolution, it fails (needing 9). The P5 don't rule alone—they just have blocking power.

India's Status: India is NOT a Permanent Member of the UNSC. This is a common exam mistake. India has served as a non-permanent member multiple times (1950-51, 1967-68, 1972-73, 1977-78, 1984-85, 1991-92, 2011-12, 2021-22). India aspires to Permanent Member status, but this requires changing the UN Charter, which itself requires agreement from all five existing P5 members—an unlikely scenario given geopolitical rivalries.

3. The Economic and Social Council (ECOSOC)

Founding Year: 1945

Composition: 54 member states elected by the GA for 3-year terms

How It Works:

• Coordinates economic and social work among UN agencies
• Convenes discussions on development, human rights, and social issues
• Accredits NGOs to participate in UN processes

Power Level: Soft power. ECOSOC has no enforcement mechanism. It's a coordinating body, bringing together specialised agencies (WHO, UNESCO, FAO, etc.) to work in tandem.

[Memory Hook] ECOSOC = "The middleman." Not as powerful as the GA (which includes all nations and passes binding resolutions), and certainly not as powerful as the UNSC. But it's essential for linking the UN's social agencies to the broader UN structure.

India's Role: India has served as an ECOSOC member multiple times and actively participates in social and economic discussions. As a developing nation with significant social challenges, India advocates for development-focused policies within ECOSOC.

4. The Secretariat

Founding Year: 1945

Composition: Headed by the Secretary-General (elected by the UNSC and GA for a 5-year term, typically renewed once for a second term). The Secretary-General is the UN's chief administrative officer and the face of the organisation globally.

Key Secretaries-General (for exam purposes):

• Dag Hammarskjöld (1953-1961): Swedish, known for interventionist role in Congo crisis
• U Thant (1961-1971): Burmese, navigated Cuban Missile Crisis
• Kurt Waldheim (1971-1981): Austrian
• Javier Pérez de Cuéllar (1982-1991): Peruvian, oversaw Cold War's end
• Boutros Boutros-Ghali (1992-1996): Egyptian
• Kofi Annan (1997-2006): Ghanaian, oversaw humanitarian interventions
• Ban Ki-moon (2007-2016): South Korean, focused on climate change
• António Guterres (2017-present): Portuguese, currently in office

How It Works: The Secretary-General runs the UN's administrative machinery, implements UNSC resolutions, convenes the GA, and serves as the organisation's voice in global crises. The Secretary-General has moral authority and soft power but cannot make binding decisions alone.

Power Level: Diplomatic power only. The Secretary-General can condemn, negotiate, and propose, but cannot enforce. Think of the Secretary-General as the CEO of a company where the shareholders (UNSC) and board members (GA) make the real decisions.

[Memory Hook] Secretary-General = "Wise elder, no real power." They can shame nations into action or propose solutions, but enforcement comes from the UNSC.

Other Key UN Bodies

The International Court of Justice (ICJ)

Founding Year: 1945

Composition: 15 judges elected by the GA and UNSC

How It Works: Settles legal disputes between nations. Any UN member can bring a case to the ICJ.

Examples: India vs. Pakistan over various boundary disputes; Iraq vs. Kuwait over invasion claims; recent cases on genocide conventions.

Power Level: Legal authority only. The ICJ cannot send troops or impose sanctions—it can only rule on law. If a nation defies an ICJ judgment, the UNSC can authorize enforcement.

The Trusteeship Council

Founding Year: 1945

Current Status: Technically still exists but is inactive since 1994 when the last trust territory (Palau) gained independence. It was designed to oversee decolonization after WWII.

[Memory Hook] Trusteeship Council = "Historical artifact." It did its job (decolonization is complete), so it's now essentially dormant. You won't see many exam questions on it.

UN Subsidiary Bodies (Most Important for Exams)

Beyond the main four bodies, the UN operates dozens of specialised agencies and programmes. The most important for SSC/RRB exams:

Key Specialised Agencies (covered in Chapter 3):

• WHO (health)
• UNESCO (education/culture)
• FAO (food/agriculture)
• UNEP (environment)
• UNHCR (refugees)
• WFP (food aid)

UN Programmes:

• UNDP (United Nations Development Programme) - poverty reduction
• UNRWA (UN Relief and Works Agency) - Palestinian refugees
• UNODC (UN Office on Drugs and Crime)

These are all subordinate to the GA and coordinate through ECOSOC.

The Veto Power: How It Works & Why It Matters

The veto is central to understanding the UNSC. Here's how it works:

1. A resolution is proposed (typically by a Permanent Member, but any UNSC member can propose)
2. Voting occurs. Nine votes needed to pass.
3. If any P5 member votes "no," the resolution dies. Even if 14 out of 15 members vote yes, one veto kills it.

Why the Veto Exists: After WWII, the USA and USSR were the two superpowers. The US wanted the UN to be powerful enough to stop Soviet aggression. But the USSR wouldn't agree to that unless it also had blocking power. Thus, the veto was a compromise: both superpowers would stay in the UN, and neither could be forced into military action against their will by the other.

[Exam Trap] "Does the veto apply to procedural matters?" Yes, but with a caveat. Procedural votes (like whether to hold a meeting) cannot be vetoed. Only substantive votes (authorizing action, imposing sanctions) can be vetoed.

Veto Statistics (as of 2026):

• Russia/USSR: ~120 vetoes (mostly during Cold War, especially on Eastern Europe)
• USA: ~80 vetoes (often to protect Israel or regional allies)
• China: ~15 vetoes (usually on human rights or sovereignty matters)
• France: ~15 vetoes (rare, mostly supporting other P5)
• UK: ~30 vetoes (rare, mostly supporting other P5)

[Memory Hook] P5 veto = "Nuclear option of diplomacy." Russia and USA used it most because they were superpowers with conflicting interests during the Cold War. Now, Russia uses it to protect allies (Syria, Belarus); USA uses it to protect Israel and maintain regional dominance.

India's Relationship with the UN

India has been a UN member since October 30, 1945—even before full independence (August 15, 1947). This makes India one of the oldest UN member states. India's contributions:

1. Non-Aligned Movement leadership: India led the NAM, which represented developing nations' interests against Cold War bipolarity. Nehru's vision of "non-alignment" shaped UN debates on colonialism and development.

2. Peacekeeping contributor: India is the world's largest contributor of troops to UN peacekeeping operations. As of 2026, over 200,000 Indian military and police personnel have served in UN peacekeeping missions since 1950. This includes operations in the Congo, Cyprus, Lebanon, Kosovo, South Sudan, and Mali.

3. Permanent Member aspirations: India seeks a permanent seat on the UNSC, arguing that the current P5 (decided in 1945) doesn't reflect 21st-century realities. India's case: largest democracy, second-largest population, nuclear power, major peacekeeping contributor, major economy. However, no expansion has occurred because the current P5 (especially USA, Russia) prefer not to dilute their veto power.

4. General Assembly activism: India has championed resolutions on climate change, development, and non-aligned causes.

Key UN Principles

The UN Charter enshrines principles that appear in exam questions:

• Sovereign equality of all members (Article 1)
• Peaceful settlement of disputes (Article 2)
• Non-intervention in internal affairs (Article 2)
• Collective security (Chapter VII) - the UNSC can authorize collective military action

Major UN Reforms & Timeline

• 1950: India becomes a permanent member of the GA (first non-Western nation with significant role)
• 1971: China's seat changes from Taiwan (Republic of China) to mainland China (People's Republic)
• 1991: Soviet Union collapses; Russia inherits USSR's P5 seat
• 2015: Ban Ki-moon proposes reforms to make UNSC more representative (rejected by P5)
• 2021: India becomes a non-permanent UNSC member for 2-year term (2021-2022)

The UN in Practice: Real-World Examples

Example 1: The Korean War (1950)

The UN's first major test was the Korean War. When North Korea invaded South Korea on June 25, 1950, the UN Security Council convened. The USSR could have vetoed a resolution authorizing military intervention, but the Soviet delegation was boycotting the council (protesting China's seat still being held by Taiwan). Without the Soviet veto, the UNSC authorized military action, and UN forces (mostly American troops) fought in Korea. This showed the UN's potential—and also its weakness: it only worked because one superpower was absent. When Cold War tensions returned, the UNSC became paralysed.

Example 2: The Cuban Missile Crisis (1962)

When the USSR placed missiles in Cuba (90 miles from Miami), the world faced potential nuclear war. However, the UN played a role in de-escalation. UN Secretary-General U Thant mediated between Kennedy and Khrushchev, proposing solutions. The crisis was resolved without nuclear war. This showed the Secretary-General's soft power: while the UNSC was paralysed (USA and USSR were adversaries), the Secretary-General could broker peace.

Example 3: India's Role in UN Peacekeeping

India has deployed 250,000+ military personnel to UN peacekeeping operations since 1950. In operations from Congo (1960s) to South Sudan (2014-present), Indian troops have died maintaining peace. This gives India credibility and influence in the UN, even without a P5 seat. When India ran for a non-permanent UNSC seat in 2021, India's peacekeeping record was a key argument.

The Debate Over UN Effectiveness

Is the UN working? This question divides experts.

Supporters argue:

• The UN prevented another World War (by deterring superpower direct conflict)
• Peacekeeping operations save thousands of lives annually
• UN humanitarian agencies (WFP, UNHCR) help millions
• UN conventions on human rights, environment set global standards

Critics argue:

• The UNSC is paralysed by vetoes (Syria vetoed 15+ times; Iraq vetoes ongoing)
• Peacekeeping is underfunded and often ineffective
• The UN couldn't prevent genocides (Rwanda 1994, Srebrenica 1995, Myanmar 2017)
• P5 nations use UN to serve their interests, not global peace
• Secretary-General has soft power but no real enforcement power

[Memory Hook] UN = "Forum for talking, not for forcing." The UN's strength is diplomacy, norm-setting, and humanitarian aid. Its weakness is enforcement against powerful nations that veto UNSC resolutions.
