I've been a bit pre-occupied with work and then I took a vacation to visit some WoW guildies that got married and just had a baby.
You were the first person I thought of when I read that specific addition. It's likely this 'player only' decision option was an easier choice than trying to balance the threat/neutrality mechanic globally to a degree where players could rampage as a minor but not jack with the AI's choices/behaviors. Frankly, I think it's fairly clever. If i'm not mistaken, decisions are modifiable so players could mess with the numbers as well, I think; I get a little overwhelmed when I open up those files. In the future I see the AAR thread exploding with demonstrations of players (dictators) marching their drafted, peasant, bucket and pitchfork minor nation army across the globe, or at least a continent or two.
