The Ledger · Medium — two to fifteen years

From The Rational Prophet (Book Four of The Laws of Game Theory)

The bet

The bet

A state that explicitly rejects the nuclear taboo in its own doctrine passes through an armed conflict without using the weapon — behaving no differently from states that uphold it.

Win

Read when the window closes, not at the first qualifying conflict: at least one such state has gone through an armed conflict, begun after publication, without use, and no detonation in conflict, by anyone, has occurred inside the window.

Lose

One detonation in conflict, by anyone, inside the window — even after a qualifying conflict has passed without use. No interpretation required.

Expiry

Two to ten years; the verdict is given when the window closes. No such state in an armed conflict begun inside the window, and no detonation, scores VOID.

Check it

Published nuclear doctrine; public confirmation of any detonation.

In protocol form

Word for word from Appendix D of the book, the Prediction Protocol, where this bet is entered as Restraint. References to sections (§) are to that appendix.

Universe

the nuclear-armed states that have published a nuclear doctrine at publication; a nuclear-armed state with no published doctrine is outside the universe, whatever its officials say. The cases scored are those states in the universe that become party to an armed conflict inside the band.

Source

published nuclear doctrine; public confirmation of any detonation. Note that the international monitoring data are not fully public, so the bet rests on public confirmation — no limitation in the case of a detonation in conflict.

Definitions

rejecting the taboo means keeping first use open in one's own doctrine, or expressly denying that these weapons are unusable; first use is open where any published doctrine permits first nuclear use in any circumstance, so a no-first-use pledge with an exception counts as open.

Baseline

the doctrinal position of each state in the universe, and the armed conflicts to which a state in the universe is already party at publication.

Calculation

the verdict is given when the window closes, not at the first qualifying conflict. HIT only if at least one state that rejects the taboo has passed through an armed conflict, begun after publication, without use, and no nuclear detonation in conflict, by anyone, has occurred inside the window. A detonation anywhere in the window is a MISS, even after a qualifying conflict has passed without use.

Note

if no state that rejects the taboo becomes party to an armed conflict inside the window, and there is no detonation, the bet scores VOID. An armed conflict to which a state in the universe was already party at publication is not a case for the win, because its course so far was known to the author; a detonation in any conflict, that one included, is still a loss. Restraint by such a state is consistent with an explanation from strategic cost. It does not exclude the influence of the norm, and a state's published doctrine is not proof of its leaders' motives.

Baseline at publication

Reading date of record: 10 October 2026

What is recorded

Doctrinal position of each nuclear-armed state with a published doctrine · the armed conflicts already running at publication to which a state in the universe is party, which do not count for a HIT, among them Russia's war against Ukraine

Value at publication

First use open in published doctrine — the universe's states that reject the taboo: United States (nuclear posture review, October 2022; the review of 2026 has not been published); Russia (deterrence fundamentals, 19 November 2024); United Kingdom (integrated review, 2021: use "only in extreme circumstances of self-defence", deliberately ambiguous); France (presidential addresses of 7 February 2020 and 2 March 2026, keeping open "a single and non-renewable nuclear warning"); India (no first use, except in response to a major biological or chemical attack, 2003); North Korea (nuclear forces law, 8 September 2022). No first use without exception: China (defence white paper, 2019). Outside the universe, having published no doctrine: Pakistan and Israel. Armed conflicts already running at publication, which do not count for a HIT: Russia's war against Ukraine; the war between the United States and Iran begun on 28 February 2026, with US strikes on Iran on 1 September 2026 and a US naval blockade still enforced on 5 October 2026 (read 10 October 2026)

Author’s probability 90% that this bet scores HIT. Registered on 10 October 2026.
