If he wills himself to be nothing, all mankind must also be annihilated; otherwise, by means of the presence of this world that the Other reveals he meets himself as a presence in the world. But this thirst for destruction immediately takes the form of a desire for power. The taste of nothingness joins the original taste of being whereby every man is first defined; he realizes himself as a being by making himself that by which nothingness comes into the world. Thus, Nazism was both a will for power and a will for suicide at the same time.
If the nihilist man is nothing, then all men must too be nothing, and any evidence to the contrary or challenge must be destroyed?
Comparing this to Nazism is a stretch because thpugh there is destruction and a willingness to kill men who are other, wanting a Reich that lasts a thousand years is not suicidal ideation.
