How does Hitler justify his hatred of the jewish people?

Hitler used a variation of tactics to justify hatred of
the Jewish people.  He had physicians identify specific features that the majority of
the Jewish population had in common.  Some of the features that he had identified were
head shape and circumference, brow distention, hook nose, and length of the
nose.

Hitler was also aware that many of the Jewish people
had booming enterprises.  He resented this and used it to his advantage.  The country
was still suffering from the damages caused by World War I.  He informed the population
that while many of Germany's best men died fighting for their country, the Jews had
stayed home and milked the economy and become rich.

Hitler
was smart enough to recognize that power would be obtained by uniting his country in
hatred.  He rationalized that he would be doing Germany a favor by ridding it of the
vermin.  He considered the Jews to be vermin.
