India-Pakistan Relations: Historical Foundations, Strategic Faultlines, and Contemporary Dynamics

Why is it in News?

India-Pakistan relations are again in discussion because the relationship between the two countries is currently passing through a phase of severe tension and almost complete diplomatic freeze.

After important events such as:

• the 2019 Balakot Airstrikes, and
• the 2025 cross-border military escalation (Operation Sindoor),

both countries have stopped meaningful political dialogue and formal trade relations.

Even though official talks remain suspended, some recent back-channel communications and statements by strategic experts and political leaders have restarted debates in India regarding:

• whether India should re-engage with Pakistan,
• under what conditions talks should happen,
• and how peace and security can be balanced together.

For UPSC aspirants, Indo-Pak relations are extremely important for:

• International Relations (IR),
• Internal Security,
• Border Management,
• South Asian geopolitics,
• Nuclear security,
• and Current Affairs.

Constitutional Basis of India’s Foreign Policy

Article 51 of the Directive Principles of State Policy (DPSP)

This Article says that India should:

India’s Core Policy Towards Pakistan

India currently follows one major policy principle:

“Terror and talks cannot go together.”

What does this mean?

• and Pakistan must first take strong action against terror groups operating from its soil.

Therefore:

• formal peace talks remain suspended,
• and future dialogue depends on improvement in security conditions.

Since independence in 1947, the two countries have experienced:

What was Partition?

Partition means:

• the division of British India into:
  • India, and
  • Pakistan.

Pakistan was created mainly as a separate homeland for Muslims.

---

Two-Nation Theory

The demand for Pakistan was based on the:

• Two-Nation Theory

This theory was strongly promoted by:

• Muhammad Ali Jinnah,
• and the Muslim League.

What did the theory say?

It argued that:

• Hindus and Muslims were two separate nations,
• with different cultures, traditions, and political interests,
• therefore they needed separate countries.

---

Effects of Partition

Partition caused one of the biggest human tragedies in history.

Major consequences:

• Massive communal riots.
• Large-scale violence.
• Migration of nearly 12–15 million people.
• Death of lakhs of people.
• Deep hatred and mistrust between communities.

The emotional scars of Partition still influence India-Pakistan relations today.

Kashmir Issue: The Biggest Dispute

The:

• Kashmir issue

is considered the core problem in Indo-Pak relations.

---

How did the Kashmir dispute begin?

At the time of independence:

• Jammu & Kashmir was a princely state ruled by Maharaja Hari Singh.

The state had:

• a Muslim-majority population,
• but a Hindu ruler.

Initially, the Maharaja wanted to remain independent.

However, in October 1947:

• tribal militias supported from Pakistan invaded Kashmir.

As a result:

• the Maharaja requested military help from India,
• and signed the:
  • Instrument of Accession,
    which legally made Jammu & Kashmir part of India.

India then sent troops to defend Kashmir.

This led to the:

• First Indo-Pak War (1947–48).

---

Result of the War

The war ended after UN intervention.

Kashmir got divided into:

• Indian-administered Kashmir,
• and Pakistan-administered Kashmir.

The border between them later became known as:

• the Line of Control (LoC).

The Kashmir issue remains unresolved even today.

---

Nuclearization of South Asia

Nuclear Tests of 1998

Major Structural Faultlines in Relations

1. Diplomatic Gridlock

What is diplomatic gridlock?

It means:

• diplomatic relations have become stuck or frozen.

After India removed:

• Article 370 in 2019,
  Pakistan reacted strongly.

Pakistan:

• downgraded diplomatic relations,
• expelled the Indian High Commissioner,
• and suspended trade.

Since then:

• political dialogue remains very limited.

---

What was Article 370?

Article 370 gave:

• special autonomous status to Jammu & Kashmir.

In August 2019:
India removed this special status and reorganized the state into Union Territories.

Pakistan opposed this decision strongly.

---

2. Shift in India’s Military Strategy

Earlier, India mainly followed:

• defensive deterrence.

What is defensive deterrence?

It means:

• trying to prevent attacks mainly through defense and restraint.

Now India increasingly follows:

• punitive retaliation.

What is punitive retaliation?

It means:

• responding strongly to attacks in order to punish the attacker.

Examples:

• Surgical Strikes (2016)
• Balakot Airstrikes (2019)

---

Pakistan’s Strategy

Pakistan tries to balance India’s stronger conventional military power through:

• asymmetric warfare,
• support to non-state actors,
• and tactical nuclear weapons.

---

What is Asymmetric Warfare?

It means:

• weaker countries using indirect methods instead of direct military confrontation.

Examples:

• proxy groups,
• irregular fighters,
• terrorism,
• covert operations.

---

Tactical Nuclear Weapons (TNWs)

These are:

Pakistan maintains a:

• “first-use policy.”

What is first-use policy?

It means Pakistan does not promise that it will use nuclear weapons only after being attacked first.

This increases strategic uncertainty.

---

Cross-Border Terrorism

Cross-border terrorism is the biggest obstacle to peace.

India accuses Pakistan-based groups such as:

• Lashkar-e-Taiba (LeT)
• Jaish-e-Mohammed (JeM)

of supporting attacks in India.

Major attacks include:

• 2001 Parliament Attack
• 2008 Mumbai Attacks

These attacks badly damaged trust between the two countries.

---

---

Contemporary Situation

Today, India-Pakistan relations are often described as:

• a “Cold Peace.”

Meaning:

There is:

• but no normal friendship either.

Relations are characterized by:
