If the idea of concentrating the Jews in a physical ghetto evolved from the notion that the Ostjuden posed a special danger, the question naturally arises as to whether the model, once created in Poland, was exported to other places under Nazi control. On the one hand, information about the ghettos in Poland was disseminated in newspaper articles, movies, and rumors, making it possible to copy the idea. On the other hand, as Seraphim had noted, “in most of the cities of central, western, and southern Europe, and in the towns of Eastern Europe where there are only a few Jews, it is impossible to ghettoize the Jews; there aren't enough of them.” It is true that Seraphim was not of high enough rank to dictate the extent to which the idea of concentrating Jews in ghettos would be implemented; nor was he ever actively involved in these efforts at ghettoization. I believe, nevertheless, that his logic, as well as his understanding of the concept of ghettoization – the concentration of Jews in physical ghettos and not simply a process of isolation from their surroundings – lay at the basis of the actions taken on the ground. The conspicuous fact is that ghettos were not established in Western Europe or in the Greater Reich.
