Again, one can make the argument that the two were tied together; the impulse that prompted the group to attempt to eradicate the Jews was also the impulse that led to their attempted conquest of Europe. Both were rooted in a perceived persecution at the end of the Great War and a need for revenge.

This, of course, stressed the super-bonds of the nation as a whole eventually causing the whole system to collapse.
