As is often the case in war, the object of the fighting is an insignificant piece of land. In most cases it has no tactical significance, but it becomes an emotional or symbolic entity. Here, the Vulcans and the Andorians have been fighting over a small planet for over a hundred years. There have been lots of casualties and this has become a sticking point. The Andorian leader has come to the realization that this is quite an annoyance. He knows the Vulcans aren't going to back down. Bit if there could be some form of diplomacy it would help. Of course, his demands are outrageous in the Vulcan's eyes, and a turnover of the planet isn't going to happen. There is a significant resistance movement on Andoria, so the leader has enemies among his own kind. This is a really tense episode and has a very realistic being about it.
