International borders are becoming blurred to a point close to disappearing.  People, money and commerce move across most of the Western world with unprecedented ease.  The nationality of corporate entities is increasingly conjectural.  Businesses manufacture, buy, sell, finance themselves and operate on a global basis.  Dual citizenship for individuals is increasingly common.  Families consisting of spouses and children of different nationalities are no longer considered unusual.  What is true internationally is also true with respect to interstate personal and business interactions.
