The Nuclear Era and Modern Frictions

If the first lesson described how the adversarial relationship hardened, this one shows how nuclearisation, terrorism and crisis management have shaped Pakistan-India relations over the past fifty years.

The 1974 Indian test

India's "Smiling Buddha" test on 18 May 1974 at Pokhran transformed the strategic equation. India framed it as a "peaceful nuclear explosion," but the underlying capability was unmistakable. Pakistan's response — accelerating its own programme under Bhutto's Multan mandate of 1972 — locked the subcontinent into a nuclear competition that would peak in 1998.

The 1974 test also produced the Nuclear Suppliers Group (NSG) in 1975, designed to control nuclear exports to non-NPT states — a regime Pakistan and India both lived within for the next quarter century.

Ziaul-Haq and the limited dialogue

The 1980s were dominated by the Afghan jihad, with Pakistan as a frontline anti-Soviet state. India-Pakistan relations were tense but stable:

• Siachen Glacier dispute (1984) — India occupied the uninhabited glacier in Operation Meghdoot; Pakistan responded with positions on adjacent peaks. The world's highest battlefield, costing both sides more in deaths from cold than combat.
• Brasstacks crisis (1986-87) — large Indian military exercises near the Pakistani border triggered a near-war standoff defused by direct talks.
• Punjab insurgency (1980s) — India accused Pakistan of supporting Sikh militancy; Pakistan denied it.

The 1998 tests and the Lahore moment

India conducted five nuclear tests on 11 and 13 May 1998, declaring itself a nuclear weapons state. Pakistan responded with six tests on 28 and 30 May 1998 at Chagai. Both states were under US-led sanctions for the rest of the year.

In an attempt to de-escalate, PM Atal Bihari Vajpayee travelled to Lahore by bus in February 1999 — a powerful diplomatic gesture. The Lahore Declaration (21 February 1999) committed both sides to:

• Confidence-building measures and nuclear risk reduction.
• A composite dialogue covering all outstanding issues including Kashmir.
• Restraint in their respective nuclear programmes.

The two governments shall intensify their composite and integrated dialogue process for an early and positive outcome of the agreed bilateral agenda… They shall undertake national measures to reduce the risks of accidental or unauthorised use of nuclear weapons.

Kargil 1999 — the limited war

Within three months of Lahore, Pakistani forces and irregulars occupied positions across the Line of Control in the Kargil sector of Indian-administered Kashmir. India launched a major counter-offensive — Operation Vijay — recapturing most peaks by July, with significant casualties on both sides.

• Washington Declaration (4 July 1999) — US President Clinton and PM Nawaz Sharif agreed on Pakistani withdrawal to the LoC.
• Strategic consequence: Kargil was the first conflict between two nuclear-armed states. It validated limited war under the nuclear umbrella but also discredited Pakistan's diplomatic credibility.
• Political consequence: the crisis contributed to civil-military strain that ended in the 12 October 1999 Musharraf coup.

Agra Summit and the 2001-02 standoff

Musharraf and Vajpayee met at Agra in July 2001. The summit ended without a joint statement, but quiet back-channel diplomacy continued.

The 13 December 2001 attack on the Indian Parliament triggered Operation Parakram — a year-long mobilisation of nearly a million troops on both sides. International mediation — particularly by the US and UK — averted war, but the standoff highlighted:

• Indian doctrine of "compellence" — using military pressure to force Pakistani action against militant groups.
• Pakistan's reliance on nuclear deterrence to prevent escalation.

The composite dialogue, 2004-08

After Musharraf and Vajpayee's January 2004 Islamabad meeting, the two sides launched a composite dialogue covering eight issues including Kashmir, terrorism, Siachen, Sir Creek and water. Notable developments:

Mumbai 2008 and the freeze

The composite dialogue ended with the Mumbai attacks of 26-29 November 2008. Ten Pakistan-origin militants of Lashkar-e-Taiba killed 166 people across Mumbai. India suspended dialogue, and although Pakistan tried Ajmal Kasab's accomplices and the LeT amir Hafiz Saeed remained at large for years, the relationship never fully recovered.

Modi era and Pulwama-Balakot

After 2014, the political environment hardened on both sides:

• September 2016 Uri attack — Indian "surgical strikes" claim across the LoC.
• February 2019 Pulwama suicide bombing killed 40 CRPF personnel.
• 26 February 2019 Balakot airstrike — Indian fighter jets crossed the international border for the first time since 1971, claiming to strike a JeM training camp.
• 27 February 2019 — Pakistan downed an Indian MiG-21 and captured Wing Commander Abhinandan Varthaman, released on 1 March in a goodwill gesture.

The Balakot episode demonstrated Indian willingness to conduct cross-border strikes under a nuclear shadow — a doctrinal shift Pakistan has been forced to account for.

Article 370 and the diplomatic break

On 5 August 2019, India revoked Articles 370 and 35A of its Constitution, ending Jammu and Kashmir's special status and bifurcating the state into two Union Territories. Pakistan:

• Downgraded diplomatic relations (expelled the Indian High Commissioner).
• Suspended bilateral trade.
• Closed airspace to Indian flights temporarily.
• Took the issue to the UNSC, where China secured an informal closed-door discussion.

Bilateral trade and ambassadorial-level relations have not been restored since.

The 2021 ceasefire and back-channels

In February 2021, the two armies' Directors-General of Military Operations announced a reaffirmation of the 2003 ceasefire along the LoC. The arrangement has largely held. Back-channel contacts — through intermediaries in the UAE — reportedly continued through 2021-22 but produced no public breakthrough.

The 2025 Pahalgam attack and crisis

A militant attack on tourists in Pahalgam, Indian-administered Kashmir in April 2025 triggered another crisis. India announced the suspension of the Indus Waters Treaty — an unprecedented step — and conducted strikes inside Pakistan. Pakistan responded with strikes of its own. International mediation led to a fragile de-escalation, but no return to normalised relations.

Outstanding issues — the bilateral agenda

The composite dialogue's eight-point agenda remains formally outstanding:

Issue	Status
Kashmir	Frozen since August 2019
Siachen	Standoff since 1984
Sir Creek (maritime boundary)	Resolution close in 2007, never finalised
Tulbul / Wullar barrage	IWT dispute
Terrorism	Mutual accusation
Economic & commercial	Trade suspended since 2019
People-to-people contacts	Visas at minimal levels
Friendly exchanges	Sports and cultural at low ebb

The structural diagnosis

Pakistan-India relations are stuck because:

1. Domestic political incentives in both countries reward hard lines.
2. Trust deficit rebuilt after every terrorist attack, ceasefire violation or strike.
3. External alignments — India's tilt toward the US and Quad, Pakistan's deepening ties with China — sharpen rivalry.
4. No costless interlocutor — third-party mediation has minimal traction.

Yet the economic logic of normalisation — trade, energy corridors, water cooperation — remains compelling. Whether and when leadership on either side chooses normalisation over conflict will define the next chapter.
