B.A. 6th Semester (Nuclear Disarmament- Role of UN & Super Powers)
Nuclear Disarmament: Role of UN and Superpowers (Detailed Explanation)
1. What is Nuclear Disarmament?
- Definition: It refers to the reduction or total abolition of nuclear weapons, including the infrastructure for their production.
- Disarmament vs. Arms Control: While disarmament seeks the total elimination of weapons, arms control aims to manage and limit the development, testing, and production of weapons, focusing on stability and risk reduction.
- Disarmament vs. Non-Proliferation: Non-proliferation focuses on preventing the spread of nuclear technology and weapons to new countries (e.g., the NPT), while disarmament specifically tackles the reduction or elimination of existing stockpiles.
- History: The movement began in 1945 following the bombings of Hiroshima and Nagasaki, which highlighted the potential for human extinction. Early efforts included the 1946 Baruch Plan, and later major treaties included the Partial Test Ban Treaty (1963), the Nuclear Non-Proliferation Treaty (NPT, 1968), and the Comprehensive Nuclear-Test-Ban Treaty (CTBT, 1996).
- Modern Initiatives: In 2017, the UN adopted the Treaty on the Prohibition of Nuclear Weapons (TPNW), which entered into force in 2021, marking the first legally binding instrument to fully ban nuclear weapons.
Despite ongoing initiatives, the global nuclear arsenal remains a significant threat, with over 12,000 warheads still in existence. Current efforts are challenged by high geopolitical tensions, particularly surrounding the Russia-Ukraine conflict, which led to the suspension of key arms control treaties like New START. While some countries advocate for a, "nuclear-weapon-free world," others rely on nuclear deterrence, creating a complex, often fragmented landscape for disarmament.
After 1945, the world understood that nuclear war could destroy humanity. Therefore, international efforts began to regulate and eventually eliminate nuclear weapons.
2. Why Did Nuclear Disarmament Become Important?
During the Cold War (1945–1991):
USA and USSR competed in nuclear weapon development.
Both built hydrogen bombs (more powerful than atomic bombs).
Developed Intercontinental Ballistic Missiles (ICBMs).
Doctrine of Mutually Assured Destruction (MAD) emerged.
MAD means:
The Doctrine of Mutually Assured Destruction (MAD) emerged during the Cold War, positing that a full-scale nuclear exchange would result in the total annihilation of both the attacker and defender, ensuring a stalemate through the threat of a guaranteed, devastating counterattack. This doctrine aimed to prevent direct conflict while driving an intense arms race and global fear.
- Definition: If one country uses nuclear weapons, the other will retaliate, causing mutual, total destruction.
- Strategic Requirement: Both sides must possess a "second-strike capability" to ensure they can retaliate even after absorbing a first strike.
- Origins & Impact: Coined in the 1960s (though rooted in earlier strategic thought), it dominated US-Soviet relations, leading to a fear of global annihilation and intense pressure for arms control agreement.
- Stockpile Peak: The global nuclear arsenal reached its peak in 1986, with approximately 70,000 warheads.
- Nash Equilibrium: Neither side had an incentive to initiate conflict or disarm.
- Nuclear Triad: Development of land, sea, and air-based delivery systems ensured the ability to retaliate.
- Arms Control: The constant fear of total annihilation pushed both sides to seek agreements to manage the threat.
3. Role of the United Nations (UN)
The UN has been the main international platform for nuclear disarmament.
(A) UN General Assembly (UNGA)
Passed its first resolution in 1946 to eliminate atomic weapons.
Adopts annual resolutions on nuclear disarmament.
Promotes Nuclear Weapon Free Zones (NWFZs).
Played a key role in adopting the Treaty on the Prohibition of Nuclear Weapons (2017).
However, UNGA resolutions are not legally binding.
(B) UN Security Council (UNSC)
More powerful because its decisions are binding.
Important resolutions:
Resolution 1540 (2004)
Prevents non-state actors (terrorists) from acquiring nuclear weapons.Sanctions against:
North Korea (for nuclear tests)
Iran (over nuclear program)
Limitation:
P5 members (USA, Russia, UK, France, China) themselves are nuclear powers. This creates a contradiction.
(C) International Atomic Energy Agency (IAEA) – 1957
Though autonomous, it works under UN system.
Functions:
Inspects nuclear facilities
Ensures peaceful use of nuclear energy
Implements safeguards under NPT
Example:
Inspected Iran under JCPOA agreement.
(D) Conference on Disarmament (CD)
Located in Geneva.
Negotiated:
NPT
CTBT
Currently deadlocked due to lack of consensus.
4. Major Treaties Explained
(1) Nuclear Non-Proliferation Treaty (NPT), 1968
Most important global nuclear treaty.
Entered into force: 1970
Extended indefinitely: 1995
Members: 190+ countries
It rests on three pillars:
1️⃣ Non-Proliferation
Non-nuclear states agree not to develop nuclear weapons.
2️⃣ Peaceful Use
Countries can use nuclear energy for peaceful purposes under IAEA supervision.
3️⃣ Disarmament
Nuclear states must work toward disarmament (Article VI).
Nuclear Weapon States (Recognized)
Only 5:
USA
Russia
UK
France
China
These are countries that tested before 1 January 1967.
Criticism of NPT
Discriminatory:
Legalizes nuclear weapons for 5 states.
Others permanently banned.
No time-bound disarmament.
Nuclear states modernizing arsenals.
India’s Position:
Refuses to sign.
Calls it “nuclear apartheid”.
Supports universal and non-discriminatory disarmament.
(2) Comprehensive Nuclear-Test-Ban Treaty (CTBT), 1996
Purpose:
Ban all nuclear explosions anywhere.
It is stronger than the 1963 Partial Test Ban Treaty.
Mechanism:
Global Monitoring System
Seismic stations
On-site inspections
Problem:
Not yet in force because:
USA has signed but not ratified.
China signed but not ratified.
India, Pakistan, North Korea have not signed.
India’s objection:
No commitment to complete disarmament.
Linked to security concerns (China & Pakistan).
(3) SALT and START Treaties
Between USA and USSR/Russia.
SALT I (1972)
Limited strategic missiles.
Created ABM Treaty.
START I (1991)
Reduced deployed warheads.
New START (2010)
Limits deployed strategic warheads to 1550 each.
Extended till 2026.
Recently weakened due to US–Russia tensions.
These treaties show superpowers can reduce weapons when political will exists.
SALT and START Treaties in details
(Arms Control Agreements between the United States and the Soviet Union/Russia)
The Strategic Arms Limitation Talks (SALT) and Strategic Arms Reduction Treaties (START) were bilateral agreements between the United States and the Soviet Union (later Russia) aimed at limiting and reducing strategic nuclear weapons during and after the Cold War.
These agreements were crucial in preventing nuclear war and stabilizing the global strategic balance.
1. Background: Why SALT and START Were Needed?
During the Cold War (1945–1991):
The United States and the Soviet Union accumulated thousands of nuclear warheads.
Both developed advanced delivery systems:
Intercontinental Ballistic Missiles (ICBMs)
Submarine-Launched Ballistic Missiles (SLBMs)
Strategic bombers
The doctrine of Mutually Assured Destruction (MAD) created a dangerous nuclear balance.
By the late 1960s:
Nuclear arsenals had reached extremely high levels.
The Cuban Missile Crisis (1962) had shown how close the world came to nuclear war.
This situation led to negotiations to control the arms race.
2. Strategic Arms Limitation Talks (SALT)
(A) SALT I (1969–1972)
Signed:
1972 in Moscow by:
US President Richard Nixon
Soviet leader Leonid Brezhnev
Main Components:
1️⃣ Interim Agreement on Strategic Offensive Arms
Froze the number of ICBMs and SLBMs.
Did not reduce weapons, only limited expansion.
2️⃣ Anti-Ballistic Missile (ABM) Treaty (1972)
This was the most important achievement of SALT I.
It:
Limited each country to 2 ABM sites (later reduced to 1).
Prevented development of nationwide missile defense systems.
Purpose:
To maintain deterrence stability.
Why was ABM important?
If one country built strong missile defense systems:
It could launch a first strike without fear of retaliation.
This would destabilize the balance of power.
Thus, the ABM Treaty preserved Mutually Assured Destruction (MAD).
Limitations of SALT I:
Did not reduce existing warheads.
Allowed modernization.
Did not limit MIRVs (Multiple Independently Targetable Reentry Vehicles).
(B) SALT II (1979)
Signed by:
US President Jimmy Carter
Soviet leader Leonid Brezhnev
Objectives:
Limit strategic nuclear delivery vehicles.
Cap total number of launchers.
However:
US Senate refused to ratify it after the Soviet invasion of Afghanistan (1979).
Though not officially enforced, both sides largely followed its limits for some time.
3. Strategic Arms Reduction Treaty (START)
Unlike SALT, START aimed at actual reduction, not just limitation.
(A) START I (1991)
Signed in 1991 by:
US President George H. W. Bush
Soviet leader Mikhail Gorbachev
It was signed just before the collapse of the Soviet Union.
Key Provisions:
Reduced deployed strategic warheads to about 6,000 each.
Limited delivery systems (ICBMs, SLBMs, bombers).
Introduced strict verification measures:
On-site inspections
Data exchange
Monitoring mechanisms
This was the first treaty to significantly reduce nuclear arsenals.
After USSR collapsed:
Belarus, Kazakhstan, and Ukraine gave up nuclear weapons.
Russia became the successor state.
START I expired in 2009.
(B) START II (1993)
Signed by:
US President George H. W. Bush
Russian President Boris Yeltsin
Objectives:
Ban MIRVed ICBMs.
Further reduce warheads.
However:
Never fully implemented.
Russia withdrew after the US withdrew from the ABM Treaty (2002).
4. New START Treaty (2010)
Official Name:
Measures for the Further Reduction and Limitation of Strategic Offensive Arms.
Signed in 2010 by:
US President Barack Obama
Russian President Dmitry Medvedev
Key Provisions:
Limits deployed strategic warheads to 1550 each.
Limits deployed ICBMs, SLBMs, and bombers.
Allows 18 on-site inspections per year.
Requires data exchange and transparency.
It was a major step in post-Cold War arms reduction.
Extension
Extended in 2021 by US President Joe Biden and Russian President Vladimir Putin.
Valid until 2026.
However:
Russia suspended participation in 2023.
Inspections have been disrupted.
Treaty effectiveness weakened due to US–Russia tensions (Ukraine war).
5. Importance of SALT and START
Reduced risk of nuclear war.
Established verification systems.
Built trust during Cold War.
Created foundation for future arms control.
Reduced total global nuclear stockpile significantly.
At the peak (1986):
~70,000 warheads globally.
Today:
~12,000 warheads.
This reduction is largely due to SALT and START processes.
6. Limitations and Current Challenges
No inclusion of China.
Only bilateral (USA–Russia).
Modernization of arsenals continues.
Growing geopolitical rivalry.
Collapse of INF Treaty (2019).
Weakening arms control architecture.
The future after 2026 is uncertain.
7. Conclusion
The SALT and START treaties represent the most significant arms control achievements of the Cold War and post-Cold War periods. While SALT focused on limiting the arms race, START moved toward actual reduction of nuclear arsenals.
These agreements helped stabilize US–Soviet/Russian relations and significantly reduced global nuclear stockpiles. However, rising geopolitical tensions and weakening trust threaten the future of bilateral arms control.
The continuation or replacement of New START will determine the future direction of global strategic stability.
(4) Treaty on the Prohibition of Nuclear Weapons (TPNW), 2017
First treaty to completely ban:
Development
Possession
Threat of use
Entered into force: 2021
Supported by:
Non-nuclear countries
Civil society groups (ICAN – Nobel Peace Prize 2017)
But:
No nuclear power has joined.
Thus, symbolic but limited impact.
5. Role of Superpowers
Nuclear disarmament largely depends on superpowers because:
USA and Russia hold about 90% of world’s nuclear weapons.
They shape global security policies.
USA
Supports non-proliferation.
Withdrawn from:
ABM Treaty (2002)
INF Treaty (2019)
Modernizing nuclear arsenal.
Russia
Reduced arsenal after Cold War.
Suspended participation in New START.
Increasing reliance on nuclear deterrence.
China
Smaller arsenal but rapidly expanding.
Follows No First Use policy.
Not deeply involved in arms reduction talks.
6. Why Nuclear Disarmament is Difficult?
Security dilemma
Lack of trust
Regional rivalries
Deterrence theory
Strategic advantage politics
Weak enforcement mechanisms
7. Present Global Situation
Around 12,000+ nuclear warheads exist.
Arms control framework weakening.
Geopolitical tensions increasing.
Modernization replacing reduction.
8. Conclusion (For 15–20 Marks Answer)
The UN has created an important legal and moral framework for nuclear disarmament through NPT, CTBT and TPNW. However, real progress depends on the political will of nuclear superpowers.
Without genuine commitment from USA, Russia and China, complete nuclear disarmament remains a distant goal.
The future of global peace depends on strengthening multilateralism and building trust among nuclear states.
Nuclear Non-Proliferation Treaty (NPT), 1968 – Detailed Explanation
1. Introduction and Background
The Nuclear Non-Proliferation Treaty (NPT) is the most important and widely accepted international treaty aimed at preventing the spread of nuclear weapons and promoting nuclear disarmament.
It was negotiated in the context of the Cold War nuclear arms race between the United States and the Soviet Union. By the 1960s, there was a serious fear that many more countries (such as Germany, Japan, Sweden, etc.) might develop nuclear weapons. This situation was referred to as “nuclear proliferation.”
To prevent the uncontrolled spread of nuclear weapons, the NPT was opened for signature in 1968, entered into force in 1970, and was extended indefinitely in 1995.
Today, it has more than 190 member states, making it one of the most widely supported arms control treaties in the world.
However, important countries like India, Pakistan, Israel, and South Sudan are not parties. North Korea joined but withdrew in 2003.
2. Objectives of the NPT
The NPT is based on three fundamental pillars:
I. Non-Proliferation (Articles I & II)
This pillar aims to stop the spread of nuclear weapons.
Obligations of Nuclear Weapon States (NWS):
They shall not transfer nuclear weapons or technology to any non-nuclear state.
They shall not assist others in acquiring nuclear weapons.
Obligations of Non-Nuclear Weapon States (NNWS):
They agree not to manufacture or acquire nuclear weapons.
They must accept IAEA safeguards and inspections.
This creates a legal distinction between:
Nuclear Weapon States (NWS)
Non-Nuclear Weapon States (NNWS)
II. Peaceful Use of Nuclear Energy (Article IV)
The NPT recognizes the right of all countries to:
Develop nuclear energy for peaceful purposes
Conduct nuclear research
Access nuclear technology
However:
This must be under the supervision of the International Atomic Energy Agency (IAEA).
Countries must accept safeguards and inspections.
This pillar tries to balance:
Security concerns + Development rights.
III. Disarmament (Article VI)
Article VI states that:
All parties must pursue negotiations in good faith toward nuclear disarmament and complete disarmament.
However:
It does not specify a time-bound framework.
It does not clearly define steps toward elimination.
This has become the most controversial aspect of the treaty.
3. Recognized Nuclear Weapon States (NWS)
Under Article IX, the treaty recognizes only five nuclear weapon states:
United States
Soviet Union (now Russia)
United Kingdom
France
China
These are states that tested nuclear weapons before 1 January 1967.
This classification permanently divides the world into:
“Legal” nuclear powers
“Non-nuclear” states
This division is the root of much criticism.
4. Safeguards and Role of IAEA
The IAEA (established 1957) plays a central role in implementing the NPT.
Functions:
Inspects nuclear facilities
Monitors uranium enrichment
Verifies peaceful use
Prevents diversion to military purposes
Example:
IAEA inspections in Iran under the JCPOA agreement.
The safeguards system is the enforcement mechanism of the treaty.
5. Achievements of the NPT
Limited the number of nuclear-armed states.
Only 9 countries currently possess nuclear weapons.
Established global non-proliferation norms.
Strengthened IAEA monitoring system.
Promoted peaceful nuclear cooperation.
Many scholars argue that without NPT, 20–30 countries might have developed nuclear weapons.
6. Criticism of the NPT
Despite its success, the NPT faces serious criticism:
1. Discriminatory Nature
The treaty legalizes nuclear weapons for only five states while permanently banning others.
This creates:
Nuclear “haves”
Nuclear “have-nots”
Critics call it a form of nuclear inequality.
2. No Time-Bound Disarmament
Article VI speaks about disarmament but:
Provides no deadline.
No enforcement mechanism.
Nuclear states continue to modernize arsenals.
3. Modernization of Nuclear Weapons
USA, Russia, and China are investing billions in:
Advanced delivery systems
Hypersonic missiles
Tactical nuclear weapons
This contradicts the spirit of disarmament.
4. Weak Enforcement
North Korea withdrew and developed nuclear weapons.
Treaty lacks strong punishment mechanisms.
7. India’s Position on the NPT
India has consistently refused to sign the NPT.
Reasons:
It is discriminatory.
It permanently divides the world.
No credible disarmament commitment by nuclear states.
Security concerns regarding China and Pakistan.
India calls the NPT a form of “Nuclear Apartheid.”
However, India:
Supports universal nuclear disarmament.
Follows No First Use policy.
Maintains responsible nuclear behavior.
Seeks entry into the Nuclear Suppliers Group (NSG).
India also proposed:
Rajiv Gandhi Action Plan (1988) for time-bound global disarmament.
8. Contemporary Relevance of NPT
Even today, the NPT remains central to global nuclear governance.
However:
Rising geopolitical tensions
US–Russia rivalry
China’s expansion
Weakening arms control agreements
All challenge the credibility of the treaty.
The future of the NPT depends on:
Genuine commitment of nuclear powers
Progress toward Article VI obligations
Strengthening IAEA safeguards
9. Conclusion
The Nuclear Non-Proliferation Treaty represents a historic attempt to control the spread of nuclear weapons and promote disarmament. While it has successfully limited horizontal proliferation, it has failed to ensure vertical disarmament among nuclear weapon states.
Its discriminatory structure and absence of time-bound commitments continue to generate criticism, especially from countries like India. Therefore, although the NPT remains the cornerstone of global nuclear governance, its long-term legitimacy depends on moving toward equitable and universal nuclear disarmament.
