I do understand your point Donsig. But I really don't see how this can work in real life. Let me reply using your analogy. What happens when a marriage only stays together because of the child? A lot of marriages actually end up like this, and it usually looks like a pretty good idea in the beginning... But the marriage is loveless, distrustful, and bitter. The respective partners may hide things from each other, and secretly undermine each other. And you may end up in a situation where as soon as the kid turns 18, one spouse secretly flies over to the most favorable jurisdiction available (call it London ) and "preemptively" starts divorce proceedings. Especially as the kid gets older, and the day of separation comes nearer, the relationship becomes ever more strained. Obviously not. But that doesn't mean we shouldn't have methods for resolving conflicts fairly and expeditiously, to minimize resentment and feelings of unfairness. And, if the other partner doesn't act in good faith with the guidelines we set out at the beginning, maybe that tells us something too. What I don't want is for the alliance to either degenerate into chaos and recrimination; or have resentment build up; because of issues we can easily foresee today and defuse today. Yes precisely, we have a very very conflicting set of interests here! That's why we need to craft a strong treaty (ahem, contract) at the beginning so we can resolve and at least control these conflicts, which perpetuates and strengthens our relationship. I do not believe it's feasible to let these conflicting interests lie and fester (i.e. saying: oh it's okay we'll deal with the issue when we get there... It'll all work out fine as long as there is trust... wait, you DO trust me right, honey?). It's much better to acknowledge these conflicts and have them in the open, where they can be dealt with properly. *** Lastly, look at how this alliance have already progressed. We have had recriminations, mutual suspicion, chaos, and inaction. Do you, or in fact ANYONE, really believe we can flip a switch and leave that all behind? Are we just going to hug, kiss, and be best friends with the best of mutual intentions for the next 100 turns? I consider myself an optimist, but I don't think this is set to happen... But with a well crafted agreement, we can clear out a lot of this bad blood and resolve future conflicts quickly, which prevents or mitigates a repeat of the above. I don't see why you are so resistant to that.
