That was the best title I could come up with. Launching a nuke causes fallout in 2 tiles out from the target. If one of those tiles is owned by another civ or city-state you will automatically declare war on that civ/city-state.
I bring proof in the form of a save game. Deluxe Digital Distribution Dcopy save and version 1.0.0.17
You should start focused on Persepolis, select the nuke in the city and launch it at ...I forgot it's name. Single remaining Persian city just to the south-west. If you target the city directly it should destroy the city, but also declare war on the (otherwise allied) city state to the south, Ragusa. All the others city states (who are also allied) will also declare war of course.
The ingame files do not mention a 2-tile radius for fallout, nor does it mention declaring war if another civs tiles are in the blast zone. Bug? Feature? Loose end? My money's on the third option.
