[Gianni]

The Jew was persecuted for his race, not his politics.

The Jews were persecuted to provide a political rallying point for the Nazis.

[fortheDeclaration]

The Jews were persecuted by the Nazi's because the Nazi's viewed them as an inferior race.

That they used them as a means to unite Germany (as a whipping boy for Germany losing WW1), does not explain the determination to wipe them out even as late as 1944-45 when the war was over.
