THE LATE 1940s SAW A LOT OF MAJOR MOVEMENTS OF REFUGEES:  In 1945, there were almost 1 million Jews living in Arab lands.  Within just a few years, that had changed radically.  When India was partitioned, 14 million were displaced. Large centuries-old German settlements in the Soviet Union, Poland and Czechoslovakia disappeared as ethnic Germans, were expelled or deported, fled or died. Only in the case of Palestinians is the refugee issue still alive, says Jeff Jacoby.
