The sacred or beloved object, one's nation to which a human being may be symbiotically attached--oppresses the self--allows for no individuality. 

The "enemy" is a projection of this beloved object--in its negative guise. The enemy is the wish for separation--to destroy the symbiotic attachment oppressing and negating the separate, individual self.

To "defend" the nation is to defend it against an "enemy," symbol of the desire to be other than the symbiotic object with one imagines one if fused. 

The "Jew," for example, was a symbol of separation from Germany, the wish for separation that Hitler could not bear to acknowledge; his wish for individuality which he could not entirely repress.

 "Hitler is Germany, just as Germany is Hitler" was the slogan that embodied Nazi ideology: no separation between Hitler and the nation. Absolute identity. 

 To kill Jews was to kill the part of Hitler (and other Germans) which longed for separation. Nazism expressed a political version of the symbiotic fantasy: absolute oneness between self and nation.

Hitler persuaded other Germans to participate in this symbiotic fantasy of oneness. Nazism meant each and every German should bind together as one to constitute the nation. No one could be allowed to be separate. This would destroy the fantasy of symbiotic oneness.

The Jew symbolized the persisting wish to escape the symbiotic bond: to be a separate individual.

Hitler spent his entire life trying to kill off his wish for separation by killing the symbol of separation from Germany, the Jew. The Jew was Hitler's repressed desire to separate, which he refused to acknowledge or embrace.

Hitler seduced the German people to share his fantasy of fusion: one Reich, one Fuehrer, one people.

The Nuremberg rallies embodied or articulated this fantasy. Each and every German was bound together as if to constitute a singular mass of flesh.

The Jew in the gas chambers was the negative version of this symbiotic fantasy: many fused into one: the obverse of the Nuremberg rallies, but simultaneously a replication of the Nuremberg rallies: many bodies fused into one body in the gas chambers: Jews piling on top of one another.
