You're right, I do. Because your plan can still be solved by a treaty, because they would be allies, and Youmi could still volunteer some of her resources if she doesn't want a war. I think this will only make the chances of a civil war higher.

[She holds up her hands, ready to let it go. Sometimes things need to change to be made better for the future, and she doesn't think that these women should be forced to make this decision to stop a war. A peace treaty give the two clans time to learn from each other their own way, rather than forcing it on them in a way that will only cause more resentment.]

If this is how the vote goes then I'll back the play. But I don't agree with it - I think you're passing over a much simpler solution that could work.
