Yeah, yeah, sure.
I recall someone stabbing Ermor in the back, and preventing me a part in Ermor's demise by taking the only access to their territory, despite participating in the battle.
Also, I am not exactly breaking a treaty with you. I don't remember setting a time limit. I have not yet entered your territory, declared war, and I will intrude errr... set the people oppressed by your strange customs free next turn.
Furthermore, given our respective positions, you are the most obvious war target. I had to choose between 2 treaty, and I didn't choose yours. This war is not exactly a surprise.
However, I wish you good luck in this war.
