The entirely mad Nazi interpretation of the meaning and significance of war had evolved from numerous German authors throughout the decades - from Bismark and Nietzche all the way up to Generals Bernhardi and von Bulow. Attached you will find the Nazi justification for organized slaughter which was encapsulated for the succeeding generations by Dr. Robert Ley, one of Hitler's willing henchmen (1890 – 1945):
"It is an expression of the highest and best in manhood... We thank Providence that it constantly calls forth our men to their last and greatest effort... Therefore, war is not the wrath of God but a blessing of God."
Ley was the mad founder of the "Adolf Hitler Schools"; to learn more, click here.
