Steve, there's too much going on in the Tournament to think of more diplomacy now.
I am allied to the Iroquois, who are allied to the French. The French were at war with the Dutch but have agreed peace I believe, although it is not reflected in-game.
The Spanish are neutral.
If any one disagrees with that, or has more to add, please do so. Steve, mail me with a treaty proposal if you want to.
