Source LinkGlobal catastrophe seems to have been narrowly avoided this past weekend, after India and Pakistan agreed to a ceasefire following the most tense military confrontations between the two states in decades. While any ceasefire is inherently fragile and vulnerable to accusations of violations, both sides have stepped back from the brink and seem committed to de-escalation. Any outbreak of violence between two nuclear-armed states is particularly fraught, and the world is right to pay attention. Yet, fortunately, no instance of such confrontation has ever resulted in a nuclear exchange. This is explained by the phenomenon that international relations theorists and security scholars term the stability-instability paradox: Because nuclear weapons fundamentally change the strategic logic of conflict, they may prevent major conflict between two nuclear-armed actors while simultaneously increasing the amount of minor conflict.
Beyond the latest episode, this phenomenon explains the continuation and outcome of much of Pakistan and India’s rivalry since Pakistan’s successful nuclear tests in 1998. Indeed, this is not the first time since they have both demonstrated nuclear capabilities that India and Pakistan have fought each other. Only a year after Pakistan first tested a nuclear weapon, India and Pakistan fought the brief Kargil War over Kashmir. There have been several flare-ups since then, the most recent of which was in 2019. Nor is this the only example of two nuclear-armed states using force against each other: The Soviet Union and China fought a brief but bloody border war in 1969, and more recently Indian and Chinese forces skirmished over their Kashmir border in 2020 and 2021.
Crises between nuclear states are never guaranteed to end so peacefully. They still require delicate diplomacy to manage and de-escalate tensions. Yet, through a better understanding of the strategic logic of nuclear and conventional conflict, we can breathe a sigh of relief at this apparent latest validation of the stability-instability paradox.
