Actually, you may not
want them to declare war. First, it never made sense to me to have a group of "monsters" declaring war (a "civilized" concept

). Second, if they declare war on the AI, it limits what the AI will do (they usually have a limit on the number of wars they'll fight concurrently). My experiments with no-diplomacy races seem to indicate that they attack about the same with no treaty as they do with a declared war, except that they spread the love around to everyone they know--in general, they're a nuisance to everybody. If that's what you want, don't allow any Messages in AI_Politics; if you just want war, adjust AI_Politics and, hmmm, AI_Anger (?) appropriately.
