I've been playing Freeciv against the built-in AI (easy, normal, and hard levels), and it seems that the AI never builds or detonates nuclear weapons (even long after the Manhattan Project world wonder has been built). Is it true that the AI will never build and/or use nuclear units?
I tried to give the AI players nuclear units using edit mode (Ctrle), but the AI players never seem to use them (I checked by periodically sending in spies). I am interested in knowing so that I can adequately prepare against nuclear attacks, and to make calculations to survive nuclear winters.
