text: One interesting question that Saunders touched on is at what point can you stop subdividing a country?  In a British context London voted against BREXIT, can they become independent of Britain and remain in the EU?  If so can a smaller portion of London then choose to go the other way?
  
  As traditional nations become less significant within the EU this question becomes more relevant.  That might become the big political question to be sorted out over the next twenty years.
