*Counts*
Helper Country: 100% of a nation's worth
Neutral Country: 100% of a nation's worth
Oppressive Country: ~15% of a nation's worth (soldiers and minimal civilians, estimated)
The Oppressive nation, of course.

See, by their success, they will create a unified country, rather than seperate ones, with minimum casualties. However, as I am
clearly a major player in these events, I will then take over from the inside using the power that decided the war and turning the super-nation into a more neutral country, thereby getting the maximum benefit for the people of ALL the nations at the minimal cost to human life. See, being too generous tends to lead to downfall in the long run, but an appropriately neutral country should be able to last a lot longer while still reasonably helping others.

I like being the one to make the decisions.
