Hi! 101 Larry
Not much different than when the Americans claim with the view of "Exceptionalism". (Manifest Destiny)

Or with the Jewish Folks claiming that they are God's Chosen People.

Hi! Curious CDN
The quote you mention (GHDI Document) was immediately after World War I . The Germans never forgave the wealthy citizens of Germany who were of Jewish origin for not supporting or financing Germany during World War One.
The following quote is from Mein Kampf, written in 1923 and is often referred to in order to point out that Hitler hated the Jewish Folks prior to the Stock Market Crash of 1929.
I suspect that Hitler was referring to these matters in 1925 which was just a short few years after WWI. Hitler blamed the loss of World War One on the fact that Jewish Folks (bankers) refused to finance the German War effort.
"On the "Big Lie"
"All this was inspired by the principle – which is quite true in itself – that in the big lie there is always a certain force of credibility; because the broad masses of a nation are always more easily corrupted in the deeper strata of their emotional nature than consciously or voluntarily; and thus in the primitive simplicity of their minds they more readily fall victims to the big lie than the small lie, since they themselves often tell small lies in little matters but would be ashamed to resort to large-scale falsehoods. It would never come into their heads to fabricate colossal untruths, and they would not believe that others could have the impudence to distort the truth so infamously. Even though the facts which prove this to be so may be brought clearly to their minds, they will still doubt and waver and will continue to think that there may be some other explanation. For the grossly impudent lie always leaves traces behind it, even after it has been nailed down, a fact which is known to all expert liars in this world and to all who conspire together in the art of lying. These people know only too well how to use falsehood for the basest purposes. From time immemorial, however, the Jews have known better than any others how falsehood and calumny can be exploited. Is not their very existence founded on one great lie, namely, that they are a religious community, where as in reality they are a race? And what a race! One of the greatest thinkers that mankind has produced has branded the Jews for all time with a statement which is profoundly and exactly true. Schopenhauer called the Jew "The Great Master of Lies". Those who do not realize the truth of that statement, or do not wish to believe it, will never be able to lend a hand in helping Truth to prevail."

In an historical context, WW One ended in November 1918 and Hitler had expressed these views in 1925 as he was attempting to explain why Germany lost the war.

Within the complete quote Hitler referred to Arthur Schopenhauer and Erich Ludendorff.

Schopenhauer was an atheist who had claimed .... "While all other religions endeavor to explain to the people by symbols the metaphysical significance of life, the religion of the Jews is entirely immanent and furnishes nothing but a mere war-cry in the struggle with other nations."
http://en.wikipedia.org/wiki/Arthur_Schopenhauer
Erich Ludendorff was convinced that the German Army had been betrayed by Marxists and Republicans in the Versailles Treaty. (Karl Marx was Ancestrally Jewish, his maternal grandfather was a Dutch rabbi, while his paternal line had supplied Trier's rabbis since 1723, a role taken by his grandfather Meier Halevi Marx.)

Ludendorff was also extremely suspicious of the Social Democrats and leftists, whom he blamed for the humiliation of Germany through the Versailles Treaty. Ludendorff claimed that he paid close attention to the business element (especially the Jews), and saw them turn their backs on the war effort by letting profit, rather than patriotism, dictate production and financing. Again focusing on the left,
