This assumption, held by modern Western people, contradicts historic facts and yet appears to be so common that even the President of the United States, Barack Obama, spoke of “Polish death camps”. The Western world of the present day does not seem to notice that these camps were built by the Germans within Polish territory under occupation; that it was the Germans who exterminated, first and foremost, Polish citizens.

The authors realize that German crimes against Polish children were accompanied by crimes against Poles committed by Soviets and Ukrainians (the massacre of Poles in Volhynia and Eastern Galicia lasted from 1943 until 1947).
