Efraim Karsh (see my review of his book below) cites from a speech by Nasser on the eve of the 1967 war. Other Israeli propagandists always cite the same words that he cited. I looked up the text of the speech from Al-Ahram issue of May 23rd, 1967. Conveniently, Karsh omits other words from the speech: like when Nasser said: "we also are working for peace."
