I've been concentrating on the easy achievements and playing ever civ before I go for the hard ones. Even my current game as France I didn't start near any wine unfortunately. I may have to play many partial games to get the civ specific achievements. No idea how to get the nuke one. May have to play a higher difficulty level for that one. You can't nuke your own cities can you? I haven't tried, but I notice you can aim a nuke for any tile within the radius of the sub.
