You shouldn't be too disappointed that they won't agree to attack. They could just as easily say they will attack (and get your hopes up) and never do it. Of course, they could say they won't attack and then do it anyway. The AI's responses to diplomacy are very...limited. They rarely have any short-term effect on the game, let alone long-term. Diplomacy usually only is a big deal when you're roleplaying your race (one of those stupid honorable Evil Overlord types, for example) or when you're in a MP game (such as on PBW).

There is entry in AI_politics.txt file that determine how soon it will agree to a new treaty. Some AIs do it faster than others. Ask them later.
Yes, AI diplomacy is very limited. We shall wait for SEV.
