Be careful about changing how quickly the AI will accept a peace treaty after a war; in my current game, my closest neighbor (Sergetti, I think) finally broke our trade alliance because I started colonizing systems they wanted. After a few turns, the AI declared war; after a couple years of war, he suddenly decided to ask for a trade alliance again. I was in the middle of redesigning my fleets and upgrading facilities, so I was going to be hard-pressed to continue the war, and decided to take advantage of the AI's offer. About five turns later, they broke the treaty again; I started invading (or glassing) planets, and after a few turns they proposed a trade alliance treaty again! At this point, I realized we were still in "no treaty" status, and decided I should declare war (rather than accept a trade alliance) to give the AI a chance to fight back more effectively (which worked, BTW; the Sergetti used a reasonably large fleet to glass most of the planets I'd just invaded over the course of a couple turns).
