"Living space in the East," a "thousand year Reich." People buy into these nonsensical fantasies

Nazism was a struggle against death: a struggle against the Jew, as a symbol of death. The German body politic could live forever--Hitler felt--only if the Jew (the idea that all bodies die) was not embedded within it.

Nazism was killing death: killing Jews as a symbol of the idea that all bodies die. Hitler's idea of "conquest" was the desire to locate and kill every single Jew--so that he and Germany could live forever.

The German body politic in a state of disintegration: Hitler’s ideology was a radical form of nationalism—revolving around the idea of the German body politic in a state of disintegration. Insofar as Hitler identified profoundly with Germany, he experienced Germany’s disintegration as the disintegration of himself. 

Nationalism revolves around the quest for narcissistic omnipotence. The ego of the nationalist seeks to expand by imagining it is fused with a vast geographical territory, and the entire "space" of national life.

However, if the ego’s wish for narcissistic expansion is projected into the idea of one’s nation, so is the ego’s vulnerability and tendency toward fragmentation.

Hitler externalized anxiety into the idea of Germany and believed his nation was in danger of disintegrating. He experienced the idea of death (his own death) as a perception that Germany—the body politic with which he identified his own body—was falling apart.

One of the ways human beings deal with the issue of mortality is through the creation of nations or "omnipotent bodies politic:" entities that seem to exist in a dimension separate from organic existence. We project the idea of our small, frail bodies into the idea of imaginary, omnipotent bodies, and then imagine that we will "live on" as if contained within these immortal bodies.

Hitler’s ideology revolved around the denial of death, suggesting that the bodies of individual Germans could fuse into one to create a single, immortal body. In Hitler’s fantasy, the German people were united (massed together as cells of an organism) to create one, indestructible body that could live forever. In this typical nationalist fantasy, the country or body politic is imagined as an entity that exists above and beyond the lives or bodies of particular individuals.

In spite of his effort to embrace Germany as "vesture for the eternal" (Fichte), Hitler’s sense of the reality of death continued to return in the form of a perception that the national body was in the process of disintegrating or decomposing. Hitler projected the idea of death into the idea of the Jew. The German body politic could become immortal if it were not for the Jewish principle of death operating within it.

If only the Jew could be eliminated, then Germany would live forever. The ideology of anti-Semitism was a struggle to overcome or defeat death.

The idea that bodies become diseased and die was projected into the Jew. Hitler committed himself to a monumental (futile) "struggle" (Mein Kampf) that took the form of attempting to "kill off" death. Hitler aspired to destroy that symbolic entity (the Jew) into which the idea of death had been projected.
