Hitler projected "the truth" into the Jew: "There are no such thing as bodies that live forever." Hitler could not bear this voice of truth. His dream of Germany was that of an immortal object that would never die. The reality of death was projected into the Jew. Killing Jews was a struggle to kill the source of death: that force within bodies that negates the idea that bodies can live forever. The Final Solution was an effort to kill death.

Hitler desired to "fuse" the German people into a single “melting pot:” uniting them as if to create a single, omnipotent body politic. The word "fuse" means to unite together by smelting or welding.

Hitler's deepest wish was to destroy the idea of separateness: Germans would abandon their individuality or individual selves to come to together to create a single, gigantic, powerful body.

The gas chambers show the other side of the coin of people melting together.  In this instance, fusion is not the ecstasy of the mass-rallies, but degradation and death. Jews in the gas chambers conveyed the other-side-of-the coin of people bound closely together.

Whereas the Nuremberg rallies represented a demonstration of the power and glory of "unity," the death camps reveal bodily closeness as destruction of individuality and death. Many bodies fused together in the gas chamber as if a single mass of flesh.

The relationship between an individual and one's nation may be described as the creation of a “selfobject:” human being and nation united to constitute a single entity. In  nationalism, one's own body and the body politic fuse into one. Nations are conceived as immortal entities that "live on" even as individuals die. A "nation" is the idea of the self--plus an immortal object fused with one's own body.

For Hitler, the German nation was an immortal object. Attachment to the Germany constituted a denial of death. 

Hitler insisted that the German body politic had to be different kind of body. Yes, he declared that Germany was a living organism, but he denied that it contained a death instinct. All living organisms move inexorably toward death. Each and every organism is doomed to die.

Hitler aspired to create a different kind of organism: one that did not contain a death instinct; that could live forever. In order to create an organism that could live forever, Hitler attempted to create a German nation that did not contain defect or disease. This is why Nazism was a medical movement (see Robert Lifton). 

The Nazis projected the idea of weakness, defect, disease and death into “others.” Jews symbolized the death instinct, what would cause the German organism or body politic to become like every other organism or living creature. Killing Jews, therefore, was killing the force within the German body politic that would lead to its death. The Final Solution was a desperate struggle to destroy death, that is, the source of death: Jews.

In Hitler's mind, if every single Jew was killed, then there would no longer be a disease or death instinct within within Germany (or in the world). Thus, --and Germany could live forever.

Hitler's realization that all bodies die was projected into the Jew, who  was conceived and perceived as a “force of disintegration” (the metaphor that appears most frequently in Hitler's speeches) within the German body politic. Hitler's career revolved around destroy the Jewish force of disintegration. If there were no force of disintegration within Germany, the nation could live forever.

Hitler repressed or denied the truth: a voice that spoke to him from within: "There are no such thing as bodies that live forever." This idea (the truth of the reality of death) was projected into the Jew. Killing Jews was a struggle to kill death, that is, to kill the cause or source of death: the force within all living creatures that leads to their demise. The "Jew" meant: there are no such things as bodies that do not die. 

Hitler conceived of Germany as a living organism or body. Since the Jew represented the reality of the death instinct within bodies, it was necessary to exterminate the Jew. The Final Solution was an effort to kill death: that force within bodies that prevents them from being immortal.

Nationalism is the fundamental political ideology that has defined the Twentieth and Twenty-First Centuries. "Nations" are those objects or entities that structure and shape "history." Each nation is constituted by its own immortality fantasy. The history of the Twentieth Century grew out competition between omnipotent bodies politic, each containing its own immortality.  fantasy.

Nazism reveals this dream of nations as immortal entities and conveys the destructiveness of this fantasy.  Creating the Final Solution, Hitler enacted the fantasy of the nation as a body that could be “immortal” if only destructive forces—national enemies—could be removed from within the nation. The Final Solution represented a collective fantasy of “saving the nation:” killing the disease lying within the nation; killing Jews; killing the death instinct; killing what prevented Germany from living forever.
