This was already tried numerous times throughout history. It is beyond me why would someone think ***civilization states*** may work in this day and age. "*Civilised*" or not, a state is as good or bad as the relationships it maintains with its own people and its neighbors.

>#Culture is what every tribe and community developed to affirm its sense of #identity. Some cultures established #states with clear #borders that further nurtured their cultures (and) were led by **“men of prowess”**: chiefs or priests, princes or kings, even emperors.
#Civilization began with the idea that the “*civilized*” had to confront the “*barbaric*.” **Men of vision** set out to *find meaning in life beyond their own borders*. They ranged from prophets and teachers who inspired those with wealth and power to spread their message to everyone.
