Greece is part of Western civilization, for the very simple reason that over the last two hundred years Greeks have determined that it should be.

Samuel Huntington, in his influential book The Clash of Civilizations and the Remaking of the World Order, published in 1996, noted the paradox: ‘Greece is not part of Western civilization, but it was the home of Classical civilization which was an important source of Western civilization.’ In fact, Greece is part of Western civilization, for the very simple reason that over the last two hundred years Greeks have determined that it should be.
