At the very heart of the conflict since its very beginning has been the Arab refusal to recognize Israel's historical legitimacy. After a very short period at the start of the last century when some Arab leaders did in fact recognize the Jewish people's link to the ancient land of Israel, Arab nationalism soon recognized that Arab hegemony in the region would only be served by a rejection of any part of the Zionist movement's claims. This remains the sticking point today. By refusing to grant historical (and therefore, Jewish) legitimacy to Israel, Abbas and other Arab leaders are setting the stage for a time when, 40 or 50 years from now, after the Palestinians have had their state for decades, Israel's right to exist will again be called into question.
