India – Pakistan Relations represent one of the world’s most conflict-ridden, historically traumatic, and strategically consequential bilateral relationships — defined by partition violence, three full-scale wars, nuclear deterrence, cross-border terrorism, territorial disputes, and the persistent failure of diplomatic normalisation despite geographic proximity, civilisational shared heritage, and economic complementarity. For UPSC aspirants studying GS Paper 2 and PSIR Paper 2 Section B, India – Pakistan Relations represent the most comprehensively examined bilateral in Indian foreign policy — touching every dimension from security, water, trade, culture, and nuclear strategy to domestic politics, great power competition, and regional stability.
Historical Background of India - Pakistan Relations
Partition, Violence, and the Birth of Hostility in India - Pakistan Relations
The foundational trauma of India – Pakistan Relations is the Partition of British India on August 14–15, 1947 — one of history’s most violent and consequential political divisions. The two-nation theory — championed by Muhammad Ali Jinnah and the Muslim League — argued that Hindus and Muslims constituted two separate nations requiring separate sovereign states. India’s founding leadership — particularly Jawaharlal Nehru and Mahatma Gandhi — rejected this theory, arguing for a secular, multi-religious democratic India that could accommodate all communities. The Partition of Punjab and Bengal triggered one of history’s largest forced migrations — approximately 14–15 million people displaced across the newly drawn borders — accompanied by mass communal violence killing between 500,000 and 2 million people in the most conservative and liberal estimates respectively.
The psychological, demographic, and political wounds of Partition created a foundational bilateral hostility that has never fully healed. Partition created the refugee problem that generated immediate political pressures in both nations; the division of assets — military equipment, financial reserves, water systems, railways — created immediate disputes; and the Kashmir question — unresolved at Partition — became the defining territorial dispute that has triggered three of the four India-Pakistan wars.
Kashmir Issue in India - Pakistan Relations
Kashmir as the Core Bilateral Dispute
Kashmir is the central, defining, and apparently irresolvable territorial dispute in India – Pakistan Relations. The Princely State of Jammu and Kashmir — ruled by Maharaja Hari Singh at Partition — had a Muslim-majority population but a Hindu ruler who initially sought independence. When Pakistani-backed tribal militias invaded Kashmir in October 1947, Maharaja Hari Singh signed the Instrument of Accession to India on October 26, 1947 — making Kashmir legally part of India. India’s military intervention pushed the invaders back but a United Nations ceasefire on January 1, 1949 left Pakistan controlling approximately one-third of Kashmir — called Pakistan-Occupied Kashmir (PoK) by India and Azad Kashmir by Pakistan.
The Kashmir dispute has multiple dimensions: territorial — India claims entire J&K as its sovereign territory based on the Instrument of Accession; demographic — Pakistan argues Kashmir’s Muslim majority should determine its political future through plebiscite as recommended by early UN resolutions; strategic — Kashmir borders China, Afghanistan, Pakistan, and multiple Indian states making it a geopolitical nexus; cultural — Kashmir’s Sufi Islamic tradition, Persian literary heritage, and Buddhist connections make it a civilisational crossroads; and domestic political — both India and Pakistan’s national identity narratives are partly constructed around their Kashmir positions.
India’s revocation of Article 370 on August 5, 2019 — removing Jammu and Kashmir’s special constitutional status and bifurcating it into two Union Territories (J&K and Ladakh) — was India’s most dramatic unilateral Kashmir action since the 1994 Parliament resolution declaring all of J&K as integral to India. Pakistan’s reaction was predictably furious — downgrading diplomatic relations, expelling Indian High Commissioner, suspending trade, and raising Kashmir at the United Nations.
Wars and Military Confrontations in India - Pakistan Relations
Conflict History of India - Pakistan Relations
India and Pakistan have fought four wars and multiple military confrontations — making their bilateral the most conflict-prone between two nuclear-armed states in the world.
The First Kashmir War (1947–48) began within weeks of Partition — Pakistan-backed tribal forces invaded Kashmir, India militarily intervened after the Instrument of Accession, and a UN-mediated ceasefire created the Line of Control (LoC) that remains the de facto border to this day.
The Second India-Pakistan War (1965) — triggered by Pakistan’s Operation Gibraltar attempting to infiltrate forces into Kashmir to trigger an uprising — expanded into a full-scale conventional war. The Tashkent Agreement (January 1966) — brokered by the Soviet Union under PM Alexei Kosygin — ended the war with both sides returning to pre-war positions. The war demonstrated that Pakistan’s military adventurism could not alter the Kashmir status quo through conventional military force.
The Third India-Pakistan War (1971) — fought over East Pakistan’s Liberation — was India’s most decisive military victory. When Pakistan’s military launched Operation Searchlight against Bengali nationalists in East Pakistan, India intervened militarily on December 3, 1971 — leading to Pakistan’s military surrender in 13 days and the creation of Bangladesh. The Simla Agreement (July 2, 1972) — signed between PM Indira Gandhi and Pakistani PM Zulfikar Ali Bhutto — established the critical bilateral principle that all disputes including Kashmir must be resolved bilaterally without third-party intervention — India’s most important diplomatic achievement in post-independence bilateral management.
The Kargil War (1999) — the most recent and only war fought between nuclear-armed India and Pakistan — began when Pakistani military forces covertly occupied strategic peaks in the Kargil sector of J&K while peace talks were underway following the Lahore Declaration (February 1999). India’s military Operation Vijay recaptured the positions by July 26, 1999 — celebrated as Kargil Vijay Diwas. The Kargil War established the dangerous precedent of limited war under the nuclear shadow and demonstrated Pakistan’s willingness to pursue covert military adventurism even during diplomatic engagement.
Cross-Border Terrorism in India - Pakistan Relations
The Defining Contemporary Challenge
Cross-border terrorism — Pakistan’s use of non-state actors as instruments of state policy — is the most defining contemporary challenge in India – Pakistan Relations. Pakistan’s “deep state” (military-ISI complex) has systematically cultivated, trained, financed, and deployed terrorist organisations including Lashkar-e-Taiba (LeT), Jaish-e-Mohammed (JeM), Hizbul Mujahideen, and Haqqani Network against India — particularly in Jammu and Kashmir and against Indian targets in the Indian hinterland.
The 2001 Indian Parliament attack (attributed to JeM and LeT) brought India and Pakistan to the brink of full-scale war — triggering Operation Parakram — India’s largest military mobilisation since 1971. The 2008 Mumbai terror attacks (26/11) — carried out by LeT operatives with direct ISI support — killing 166 people including 26 foreign nationals — was the most devastating terrorist attack on Indian soil and permanently transformed India-Pakistan bilateral atmosphere. India’s demand for prosecution of 26/11 mastermind Hafiz Saeed and other perpetrators has been the central bilateral sticking point ever since — Pakistan’s failure to meaningfully prosecute 26/11 planners has made diplomatic normalisation politically impossible in India.
The 2016 Uri attack — killing 18 Indian soldiers — triggered India’s surgical strikes across the LoC on September 29, 2016 — marking a qualitative shift in India’s deterrence posture — demonstrating willingness to conduct limited offensive military operations across the LoC in response to Pakistani-sponsored terrorism. The 2019 Pulwama attack — killing 40 CRPF personnel — led to India’s Balakot airstrike on February 26, 2019 — the first Indian airstrike across the international border since the 1971 war — escalating bilateral military confrontation to a new threshold.
Other Key Issues in India - Pakistan Relations
Indus Waters Treaty
Indus Waters Treaty (IWT) — signed on September 19, 1960 and brokered by the World Bank — divides the six Indus River system waters between India and Pakistan. India receives the eastern rivers (Ravi, Beas, Sutlej) and Pakistan the western rivers (Indus, Jhelum, Chenab). The IWT survived three wars and decades of bilateral hostility — earning its reputation as the “world’s most enduring bilateral water agreement”. However, India’s notice for modification of IWT following the Pulwama attack — citing Pakistan’s continued terrorism — has raised the prospect of weaponising water in the bilateral for the first time, creating alarm in Pakistan which is critically dependent on Indus waters for 70% of its agricultural irrigation.
Trade Relations
Trade relations — suspended and resumed multiple times — reflect the bilateral’s oscillating political temperature. India revoked Pakistan’s Most Favoured Nation (MFN) status following the Pulwama attack (2019) and imposed 200% customs duty on Pakistani goods. Bilateral trade has been minimal — well below potential given geographic complementarity. Academic studies suggest full bilateral trade normalisation could generate $37 billion in bilateral trade — compared to the current sub-$2 billion facilitated mostly through third countries.
Nuclear Deterrence
Nuclear deterrence creates the most existential bilateral dimension. Both India and Pakistan are undeclared nuclear weapons states outside the NPT framework — with estimated 160+ nuclear warheads each. Pakistan’s “Full Spectrum Deterrence” doctrine — including tactical nuclear weapons (TNW) designed to deter Indian conventional military superiority — has created the world’s most dangerous nuclear standoff. India’s “Cold Start Doctrine” (or Proactive Strategy) — rapid limited conventional military incursion across the border below Pakistan’s nuclear threshold — is specifically designed to create conventional military options despite Pakistan’s nuclear deterrence. The India-Pakistan nuclear dynamic — with short missile flight times, command and control challenges, and a history of military escalation — is considered by international security analysts as the world’s most dangerous nuclear flashpoint.
Theoretical Frameworks for Understanding India - Pakistan Relations
Scholarly Perspectives on India - Pakistan Relations
PSIR Paper 2 scholars have provided distinct theoretical frameworks for understanding the India-Pakistan conflict. Sumit Ganguly’s “Security Dilemma” framework — argues that India-Pakistan conflict stems from mutual insecurity spiral where defensive actions by one side are perceived as offensive threats by the other. Touquir Hussain’s “Social Constructivist” framework — argues that the conflict is rooted in constructed national identities that define India and Pakistan as existential threats to each other — resolution requires identity reconstruction not just confidence-building measures. Hussain Haqqani’s “Insecurity Dilemma” framework — argues that Pakistan’s military establishment deliberately perpetuates India threat perception to justify military dominance over Pakistan’s civilian government — the conflict serves institutional interests of Pakistan’s deep state. Stephen Cohen’s framework — argues that Pakistan is a “troubled state” whose domestic dysfunctions — military dominance, Islamic radicalism, economic weakness — make bilateral normalisation structurally impossible regardless of India’s policy choices.
Pakistan’s National Security Policy 2022 and India - Pakistan Relations
A Shift or Mere Rhetoric?
Pakistan released its first-ever National Security Policy (NSP) in 2022 under PM Imran Khan — emphasising “geo-economics over geo-politics” and suggesting Pakistan’s recognition that economic development rather than military confrontation with India serves its national interest better. The NSP’s position on India was relatively moderate — suggesting interest in normalised economic relations. However, Pakistan’s deep state (military-ISI) controls foreign and security policy — the NSP’s civilian government orientation was quickly superseded by the April 2022 Imran Khan ouster and subsequent political instability. Critics argued the NSP represented rhetorical moderation without structural change — Pakistan’s military establishment’s India threat perception remained unchanged despite the policy document’s language.
India’s Current Policy in India - Pakistan Relations
Current Stand and Policy Options
India’s current approach to Pakistan is guided by several clear policy positions under the Modi government. First, “talks and terror cannot go together” — India refuses diplomatic engagement while Pakistan sponsors cross-border terrorism — a non-negotiable precondition for bilateral dialogue. Second, isolation strategy — India has systematically worked to diplomatically isolate Pakistan internationally — at FATF (where Pakistan was on the Grey List from 2018–2022), in SAARC (where India has blocked SAARC summits since 2016 Uri attack), and in bilateral international forums. Third, punitive deterrence — surgical strikes and Balakot airstrike demonstrated India’s willingness to escalate militarily in response to Pakistani-sponsored terrorism. Fourth, economic pressure — revoking MFN status, imposing tariffs, blocking trade routes. Fifth, Article 370 abrogation — India’s most dramatic unilateral Kashmir action reducing the international legitimacy of Pakistan’s Kashmir claims by changing ground reality.
As Sumit Ganguly argues, India’s Pakistan policy reflects a “coercive diplomacy” approach — using military, economic, and diplomatic instruments to impose costs on Pakistan for its terrorism sponsorship without triggering full-scale war. C. Raja Mohan suggests India needs a more “calibrated engagement” — maintaining pressure while keeping diplomatic channels open to prevent miscalculation in a nuclear environment. Harsh V. Pant argues that India’s post-Balakot deterrence posture has fundamentally altered Pakistan’s cost-benefit calculation on terrorism sponsorship — though the structural incentives for Pakistan’s military to maintain India threat perception remain unchanged.
Conclusion on India - Pakistan Relations
India – Pakistan Relations remain the most intractable, dangerous, and consequential bilateral in South Asia — where partition trauma, territorial disputes, nuclear deterrence, state-sponsored terrorism, and domestic political compulsions on both sides create structural barriers to normalisation that have resisted every diplomatic initiative for over seven decades. The “talks and terror cannot go together” doctrine, Article 370 abrogation, Surgical Strikes, and Balakot have defined India’s contemporary bilateral posture as assertive deterrence rather than negotiated engagement. Whether this posture successfully changes Pakistan’s strategic calculus — or merely manages the conflict at a stable but permanently hostile equilibrium — remains the defining open question in South Asian strategic studies. For UPSC aspirants, India – Pakistan Relations offer the most comprehensive and challenging case study of how history, identity, territory, nuclear weapons, terrorism, and domestic politics simultaneously shape a bilateral relationship in the 21st century.

Q1. [UPSC CSE Prelims 2013]
Q: With reference to the Simla Agreement (1972), which of the following statements is/are correct?
1. It was signed between PM Indira Gandhi and Pakistani PM Zulfikar Ali Bhutto.
2. It established the principle that all India-Pakistan disputes including Kashmir must be resolved bilaterally without third-party intervention.
3. It converted the ceasefire line into the Line of Control (LoC).
(a) 1 only
(b) 1 and 2 only
(c) 2 and 3 only
(d) 1, 2 and 3
Answer: (d) 1, 2 and 3
Explanation:
The Simla Agreement, signed on July 2, 1972 after the 1971 war, was concluded between Prime Minister Indira Gandhi and Zulfikar Ali Bhutto. It established the principle that India and Pakistan would resolve their disputes bilaterally without third-party mediation, and it converted the earlier ceasefire line into the Line of Control. Hence, all three statements are correct.
Q2. [UPSC CSE Prelims 2014]
Q: The Indus Waters Treaty (1960) between India and Pakistan allocated which rivers to each country?
(a) India received Indus, Jhelum, Chenab; Pakistan received Ravi, Beas, Sutlej
(b) India received Ravi, Beas, Sutlej; Pakistan received Indus, Jhelum, Chenab
(c) India and Pakistan received equal shares of all six rivers
(d) All six rivers were placed under joint India-Pakistan management
Answer: (b) India received Ravi, Beas, Sutlej; Pakistan received Indus, Jhelum, Chenab
Explanation:
The Indus Waters Treaty divided the six rivers of the Indus system between the two countries. India received the eastern rivers — Ravi, Beas, and Sutlej — for unrestricted use, while Pakistan received the western rivers — Indus, Jhelum, and Chenab — subject to limited Indian usage rights for specified purposes such as hydropower. Therefore, option (b) is correct.
Practice Questions
Q: The 'Tashkent Agreement (January 1966)' following the 1965 India-Pakistan War is significant because:
(a) It was mediated by the Soviet Union and required both sides to withdraw to pre-war positions
(b) It permanently resolved the Kashmir dispute through UN arbitration
(c) It established the Line of Control for the first time
(d) It was signed by PM Nehru and Pakistani President Ayub Khan
Answer: (a) It was mediated by the Soviet Union and required both sides to withdraw to pre-war positions
Explanation:
The Tashkent Agreement, signed on January 10, 1966 in Tashkent, was brokered by Soviet Premier Alexei Kosygin after the 1965 India-Pakistan War. It was signed between Indian Prime Minister Lal Bahadur Shastri and Pakistani President Ayub Khan. The agreement required both sides to withdraw to pre-war positions and release prisoners of war. It did not resolve the Kashmir dispute and did not establish the Line of Control, which came later under the Simla Agreement of 1972.
Q: India's 'Cold Start Doctrine' (or Proactive Strategy) in the context of India-Pakistan relations refers to:
(a) India's nuclear doctrine of minimum deterrence against Pakistan
(b) India's rapid limited conventional military incursion strategy designed to create offensive options below Pakistan's nuclear threshold
(c) India's diplomatic strategy of maintaining cold relations with Pakistan
(d) India's economic sanctions strategy against Pakistan
Answer: (b) India's rapid limited conventional military incursion strategy designed to create offensive options below Pakistan's nuclear threshold
Explanation:
Cold Start Doctrine refers to a rapid and limited conventional military strategy associated with Indian military planning after Operation Parakram. Its purpose is to create offensive options below Pakistan's nuclear threshold by enabling quick mobilisation and shallow incursions. It is not a nuclear doctrine, diplomatic posture, or sanctions policy. The doctrine reflects the strategic challenge of responding to Pakistan-sponsored terrorism under a nuclear deterrence environment.
