 Judith Olsak-Glass writes that Piotrowski's premise in "Poland's Holocaust" is that Poland's borders and sizable minorities were the main factors leading to the Holocaust in Poland.Piotrowski posits that the aspirations of Ukrainians for a "greater Ukraine", Belorussians for a "reunited Belarus", and Jews for a "Jewish state within the Polish one" were a smoldering issue in the Second Polish Republic.Piotrowski argues that at the outbreak of the war "radical members" of the minorities sided with the Nazis and Soviets.
