On the advantage of "the melting pot"............

One of the amazing historical benefits that have accrued to the United States of America is the high degree to which immigrants of all different ethnic origin have chosen to surrender their ethnicity and become, simply, Americans.  While this is not uniformly true, and while many have sought to make a career out of hyphenated politics, it is true enough to make America different, and stronger, than much of the world.  Perhaps this occurred because people have flocked to these shores by choice, rather than being made part of a "country" designed by foreign powers.  Better historians than me can, and probably already have, sort this out.  Regardless, it certainly can be messy when ethnicity remains a priority and ethnicity does not align with national borders.  For the latest case in point, consider the Kurdish question.
