The definition of 'strike' is very narrow: it must be an aerial strike (drones, missiles, bombs) by the US or Israel impacting Iranian soil or official diplomatic compounds. Intercepted missiles, SAM debris, artillery, ground incursions, and cyberattacks are excluded. Furthermore, it requires a 'full calendar day' without a strike, and if a strike isn't confirmed by credible reporting within three days, it counts as not happening. These strict exclusions mean severe military conflicts could occur while the market still resolves to 'Yes' (no military action).
