The Nazi's hated Christianity,...
Simply not true. The Nazis, including Hitler were Christians (specific quotes available to support that assertion if requested). They even maintained diplomatic connectioins with the Vatican throughout the war.
... hated Gods chosen people the Jews ...
As did most of the world. Anti-semitism was rampant world wide and as strong in the US as anywhere else. Read the writings of Henry Ford sometime. The great driving force of the Balfour Declaration was to help get the Jews out of Europe and anywhere else.
The leaders had a great deal of pride and haughtyness.
As do all world leaders.
Yet they were NOT the group that won.
Barely.
The Atomic Bomb was made possible by some of the "inferior genetic" scientists whose people were hated and targeted.
Yes, as well as by Christians and even quite a few Atheists and Deists.
Clearly, the "survival of the fittest" appears to be survival of the chosen.
Like Joseph Stalin and Mao Zedong?
