Re: The Undiscovered Country and Yesterday's Enterprise
So what could have caused the first treaty to break down?
Look at our own history. Treaties break down all the time for all kinds of reasons. Especially when you have a treaty between two powers that don't trust each other at all. On top of that, more so when one of the signatories is a race of people who love fighting for it's own sake.
