The cold-blooded and planned murder of four rabbis, three American and one British, in West Jerusalem by Palestinian Arabs was celebrated both in Gaza and the West Bank ("Tragedy in Jerusalem," Nov. 19). This demonstrates that there can be no permanent nor true peace between Israelis and Palestinian Arabs. While Palestinian Authority President Mahmoud Abbas, under pressure from the U.S., condemned the murders, he chose to lay the blame equally on Israel for so-called provocative actions. As usual, all other Palestinian Arab leaders in the West Bank and Gaza congratulated the murderers for their "heroic" actions. Even in Jordan, the legislature observed one moment of silence out of respect and in memory for the murderers, condoning their actions.
