In South Africa's apartheid upheaval, Nelson Mandella sat down with Mr. de Klerk to discuss that nation's transformation.  No such partner exists in Palestine's political structure - or ever did.  When the PLO was founded in 1964 their aim was not the creation of lands under Egyptian (Gaza) and Jordanian (West Bank) authority, but rather the elimination of Israel and the founding of an Arab Palestinian state encompassing the entire area - sans Jews.  Soon after, in 1967, at the Arab Summit in Khartoum, leaders of every Arab state attending determined and have since hewed to: No recognition of Israel, No negotiating with Israel, No peace with Israel.   Unlike Mr. de Klerk, Israel has no [partner with which to discuss peace.  Seems to me, it's much easier than going to war. . . again.
