Regarding the topic itself we have a real issue with people actually doing the whole "attacking" part, people not having treaties wont change that.
Xiph acts like he is the only person with allies on the other side. Still amazing that people just can't accept that their partner choose the other side, and needs to deal with it. If you want to help them do it after the war.
