"The Polish nation as a whole acted heroically in their attitude towards the Jews".
The Jewish writer David Klin, who was a liaison officer between the Home Army and the Zegota during the war, described to the Polish columnists Andrzej Chciuk his speech delivered at one of his meetings in Israel. When he said that 'the Polish nation as a whole acted heroically in their attitude towards the Jews' he was immediately shouted down that it was not true. Klin answered, 'I know it is true because I was there.'
