So, let’s say side A has told side B to do “X”. Maybe Side A even throws in an “or else” with their demands. Doesn’t really matter what X is for this discussion. Side B does not comply with Side A’s request. Side B might even respond with, “go ahead and try it.” Side A attempts to force Side B to comply. Side B actively resists, and meets force with force. From this point it’s off to the proverbial races with Civil War.
