Since both of you called raid on each other (which is really bizarre to be honest) both sides can't declare a war, as per the aggressor in a raid being unable to declare war.
Though someone else should throw in their word as well, as I could be technically seen as biased since I am buds with a couple of the BoS.
Note: I was involved with the raid, so, do get another opinion.
War......war never changes....or does it? The answer is no....unless it is yes. War has changed........has it? No.....yes......maybe?
