Albright is Jewish - a claim she has denied in the past. It appears her grandparents were Jewish and possibly even died in concentration camps. And there may be at least a dozen of her relatives who also died at the hands of the Nazis. Albright was raised a Catholic after her father, diplomat Josef Korbel, moved his family to England after part of Czechoslovakia came under Nazi rule in 1938. When she married, she became an Episcopalian.
Religion has no bearing on whether people succeed in their careers.
The only time it is issue is when other people constantly cast a shadow on it for all the world to see. Religion also has no bearing on whether people can communicate effectively with other people - in this case, whether Albright can assuage hard feelings between leaders and countries that have been at war for centuries. And if Albright does confirm that she is Jewish, there is no telling whether she will discard all of her Catholic upbringing and embrace her Jewish roots. If she was not raised Jewish and does not consider herself Jewish, she is not Jewish. Her actions at the time of her wedding only confirmed that.
