Yeah, I thought that myself as I wrote it. (The first bit, I mean, about it not actually being their war; not your more accurate title - that genius is yours alone!)
Maybe in the sequel the player could control some pan-galactic super-intelligent alien threat which was occupying all the AI's time during the first game. Then "AI's War" would actually make sense, and be quite poignant. Although less so now that I've given away the surprise. Oh well, throw that one in the bin then!
