i'm a political failure!!!

Don't get too upset; in coding the AI to make it more challenging, it also became moodier; it frequently breaks treaties within a couple turns. The main reason is that many of the AI's now get angry fairly quickly. And the source of anger is generally tied to allies (!) building colonies in the AI systems, allies having ships in the AI systems, the AI noticing lots of colonizable planets in the (human) ally's system, but the (human) ally already has colonies on those planets... you get the idea. I've found that offering gifts in the first couple turns of a treaty will help get over the initial anger, and sometimes they'll maintain a treaty even when they get "murderous" towards you. BTW, offering gifts and/or tribute sometimes helps get a treaty in the first place.
