it _deeply_ irritates me that, for all the relatively useless espionage options there are in the game, there is no mechanic for using espionage to investigate who is putting people on the Slave Market, and it angers me even more that there's no mechanism to make an immediate casus belli out of it other than "Ideology", which requires an exact hit on egalitarian vs. authoritarian or xenophile vs. xenophobe and, in any case, is not a "total war" state
