By now, the images have become familiar to all of us: the race across a barbed-wire border on a moonless night; a boat, overcrowded with desperate people, preyed upon by modern-day pirates; cars, piled high with furniture, stuck at an entry point; an overnight city of white tents set against the mountains. There is no corner of the earth where the classic drama of the refugee has not unfolded.

If anything, we are seeing today an unprecedented number of the world's citizens who have been made refugees as a result of civil conflicts, environmental disasters and, ...
