Wandycz & Biskupski (2003), pp. 70–75, "Morgenthau issued his report – popularly regarded as the definitive statement of the commission, but in effect a minority opinion – early in October, and its conclusions reflected the author's ambivalence. Concerning the burning question of the inquiry, he denied the authenticity of the alleged pogroms and cleared Warsaw of direct responsibility for the isolated 'excesses' that had occurred, attributing them above all to 'the chaotic and unnatural state of affairs' of the preceding year." — Google Books, previewWandycz, Piotr Stefan; Biskupski, Mieczysław B.
