Well, for Ares it's any war. I like how O'Connor illustrates the difference in Ares and Athena's approach to war, and when one will override the other. Seeing his take on Ares involvement (or lack of) in the Trojan war makes a more realistic and understandable reasoning than most. If Zeus hadn't gone all scary lightening, Ares would probably have ignored him like he frequently does and gotten all up in the war anyway. Watching how each Olympian sticks their fingers into the pie, and the turning point for when they stop enjoying the conflict is also illuminating. Who knew Ares would get so upset about the death of a son he had no real contact with?
