National Socialism places the race as the representation of a nation, and not it's national boundries. For the nation/race to survive, the duty of the state is the protection of this racial body.
Nation for Hitler was inseperable from the idea of race. Each nation, he wrote in mein kampf, 'is only a multitude of more or less similiar individual beings'; these beings were 'linked by blood', a similarity of values and a developed racial consciousness. Where Stalin argued that 'each nation is equal to any other nation', Hitler insisted that they existed historically in a state of permanent inequality. He devided nations into two categories: higher races imbued with the urge to 'self-preservation and continuance' and capable of both creating and sustaining a superior culture; lower races destined for biological degeneration and cultural sterility. Hitler's nations were communities locked into permanent confrontation, exclusive and belligerent from nature and necessity. They could not be defined by a common territory, since a vigorous but geographically restricted people had the right to seize all the additional land it needed for its long-term sustenance.
The state, in Hitler's view, should be coterminous with nation or race. The only purpose of the state was to protect the biological purity of is population, raise levels of racial awareness and organize itself to fend off other nations that trespassed on its vital interests. All non-Germans were, by definition, incapable of being or becoming full members of Hitler's 'Germanic state of the Germanic nation'. He rejected out hand any idea of internationalism, regarding it as the mortal enemy of the true racial state and inspiration of the Jews. In its place Hitler expected 'the whole life and action' of a people to be devoted to asserting its own national values at the expense of other, alien cultures. The chief enemy of this ambition was the Jewish people because they alone, the 'mightiest counterpart' of the racial state, had throughout history been the instrument of what Hitler called 'denationalization'. Without a fixes territory themselves - 'the race without roots' - the Jews flourished parasitically on the body of the unsuspecting host nation, sucking its culture dry, polluting its biological heritage. Hitler's nationalism was exclusive and defensive, and expression of cultural superiority and racial affinity.
Hitler's concept of the state was based solely on the 'preservation and intesnification' of a single nation to which all political and social ambitions were to be ruthlessly subordinated.
