| contents | <p>This analysis estimates the probability of tactical nuclear weapon (TNW) use by the US-Israel coalition in the ongoing conflict with Iran, employing a simplified Bayesian odds model with multiplicative OR multipliers for identified input variables. The baseline prior (3% at week 6) is combined with seven structural factors - including interceptor depletion, diversionary escalation, China/Russia signaling, and the Taiwan threat - yielding a raw estimate of 57%, subsequently revised to a realistic range of 25-55% (midpoint ~40%) after sensitivity analysis and red team review. <strong>The assessment identifies escalation mechanisms, trigger scenarios, falsification conditions with a verification schedule, and cascade effects including conditional probabilities of Russian tactical nuclear use in Ukraine (30-50%) and a full nuclear war chain (1-4%). I</strong>nhibiting factors are analyzed qualitatively as binary conditions rather than continuous modifiers<strong>. The document concludes that even conservative estimates place the risk at levels comparable to the 1962 Cuban Missile Crisis, and that the scenario cannot be dismissed as improbable. </strong>The primary value of the analysis lies in identifying variables, mechanisms, and update indicators rather than in specific percentages. This report constitutes an operational supplement to the War-Peace Validator module of the Triptych framework (DOI: 10.5281/zenodo.17219502).<br>This report was originally written in Polish; the English version is a translation.</p> |
