I spent ages amassing several fleets on my border with the Kox ready for an attack, when I felt the time was ready I sent my fleets to attack their outlying colonies. To my dismay however I found that I was mysteriously allied with them! I dont recall ever accepting an alliance with them and I cant find any way to break this alliance (there is only a trade embargo option). My relations with them are neutral. I am also only able to make and break alliances with a few of the other factions but not all of them. Strangely enough I am able to ally with two of the three factions at war with the korx and they dont seem to mind me being allied with their greatest enemy as well as themselves.
I dont know if anyone else has had this problem so if anyone has any idea how to fix this problem or if there is a way to declare war without physically attcking something I would greatly appreciate it. The galaxy is pretty boring when im not at war!
