Provide one piece of evidence that Hitler used to support his plan to invade Poland and explain HOW it supports

Question

Here is the supplementary material that I was given for the question>

Our strength consists in our speed and in our brutality. Genghis Khan led millions of women and children to slaughter – with premeditation and a happy heart. History sees in him solely the founder of a state. It’s a matter of indifference to me what a weak western European civilization will say about me. I have issued the command – and I’ll have anybody who utters but one word of criticism executed by a firing squad – that our war aim does not consist in reaching certain lines, but in the physical destruction of the enemy. Accordingly, I have placed my death-head formations in readiness – for the present only in the East – with orders to them to send to death mercilessly and without compassion, men, women, and children of Polish derivation and language. Only thus shall we gain the living space (lebensraum) which we need. Who, after all, speaks today of the annihilation of the Armenians?

-The text above, written by Adolf Hitler, is the English version of the German document handed to Louis P. Lochner in Berlin. This version was published by Kevork B. Bardakjian, Hitler and the Armenian Genocide (Cambridge,

Massachusetts: The Zoryan Institute, 1985).

Answer 1

Hitler was appealing to the reaction against the humiliation Germany suffered after WW1

Hitler admired Nietzsche, and would regularly visit a museum where Nietzsche's sculptured head was on public display, to admire it. Hitler edited Nietzsche's writings to make it seem he was in favor of creating a super race, the German race, like Darwin's survival of the fittest, with Germans the fittest race, the Aryan race.

but Poland was more a matter of the majority population, with many areas of Poland mostly German. It was like Russia today claiming areas of the Ukraine due to their majority Russian populations. Seems reasonable? If countries are primarily about race and ethnicity? Or is nationhood about something greater than its ethnic percentages? or like Mexico claiming Southwest America as "temporarily occupied territories" in its maps. Should the US give back to Mexico California, Arizona, New Mexico, Texas and parts of Utah, Nevada and Colorado? They all used to be part of Mexico And today, increasingly more Mexican national population.

Territorial disputes are worldwide throughout history. Florida and Georgia have had disputes over their common border. Canada and the US disputed its borders with "44 40 or fight" a near major war over the border.

What makes Germany singularly guilty of massive war crimes for disputing its borders? (ignoring the Holocaust, for the moment-- original Nuremberg trial charges were for Kellogg-Brand violations, not any Holocaust charges)
