Sorry for the poor choice of the word "guess".  What I meant to say is that
the political structure is not as stable as desirable even though they are
based upon man made laws.  BTW, I wrote the Terran Atlas based upon this
database.  Some of us are very interested in keeping an accurate history
even though most users on this list probably have no use for data that is
more than a month old.
