Comment: Relevance of Diplomacy in the Nuclear Age. (1999, 20 Marks)
In The Absolute Weapon (1946), Bernard Brodie argued that the chief purpose of military establishments would henceforth be to avert wars rather than win them. That shift moved the burden of security from the battlefield to the negotiating table. Nuclear weapons were expected to make diplomacy redundant, since a state able to destroy another need not persuade it; eight decades of record show the opposite.
The case that diplomacy declined
- Threat displaces bargain. A state with assured destructive capacity appears able to dictate rather than negotiate, and bipolar confrontation left little room for classical accommodation.
- Compressed decision time. Warning measured in minutes leaves no interval for the deliberate exchange of notes classical diplomacy assumed.
- Morgenthau’s lament. In Politics Among Nations (1948), Hans J. Morgenthau traced a “decline of diplomacy” to instant communications, the depreciation of negotiation in an ideological age and the inexperience of the superpowers. Yet he concluded that peace required diplomacy’s revival, not its replacement.
Why diplomacy became indispensable
- Deterrence is communication. Deterrence needs capability, credibility and communication; the third is diplomacy’s function. Thomas C. Schelling (Arms and Influence, 1966) called the use of the power to hurt a “diplomacy of violence”: nuclear strategy is bargaining, not fighting.
- Crisis management. The Cuban missile crisis (October 1962) was settled through the Kennedy–Khrushchev letters, a back channel between Robert F. Kennedy and Anatoly Dobrynin and a private understanding on US missiles in Turkey.
- Arms control. The Partial Test Ban Treaty (1963), the NPT (1968), SALT I and the ABM Treaty (1972), the INF Treaty (1987) and New START (2010) were negotiated texts; non-nuclear states used diplomacy to bring the TPNW into force in January 2021.
- Communication machinery. The Washington–Moscow hotline (1963) and missile-test pre-notification are diplomacy’s nuclear-age offspring.
The South Asian test
- Confidence-building. Under their 1988 agreement on nuclear installations, India and Pakistan have exchanged lists every 1 January since 1992, through Kargil, the 2001–02 standoff and Balakot. The Lahore MoU (1999) and the 2005 missile-test pre-notification agreement extended this machinery.
- Crisis termination. During Operation Sindoor (May 2025) hostilities between two nuclear-armed states ended on 10 May 2025 through the DGMO hotline, not on the battlefield.
- Ending isolation. After the May 1998 tests, Jaswant Singh made India’s case abroad (“Against Nuclear Apartheid”, Foreign Affairs, 1998) and, through fourteen rounds with Strobe Talbott, rebuilt the US relationship that later produced the civil nuclear initiative (2005) and the NSG waiver of September 2008. Credible minimum deterrence and no first use are themselves declaratory diplomatic signals.
The contemporary warning
- Arms-control erosion. New START expired on 5 February 2026 with no successor, leaving the two largest arsenals without negotiated limits for the first time since 1972.
- Iran. The 2015 nuclear deal unravelled after the US exit (2018); Israeli and US strikes on Iranian nuclear sites followed in June 2025, UN sanctions were reimposed by snapback in September 2025, and a US–Israeli war on Iran began on 28 February 2026. Force filled the gap diplomacy left without settling the question: a Pakistan-mediated truce of April 2026 broke down in July, and talks were continuing in late September 2026.
Conclusion
Nuclear weapons removed war as a rational means of settling disputes among their possessors, and so made diplomacy the main instrument left for managing rivalry. Its form changed from leisurely negotiation to crisis management, verification and hotlines, but its relevance rose. The danger today lies not in diplomacy’s irrelevance but in its neglect: arms-control erosion and multipolar nuclear competition are diplomatic failures, not technical ones.
