Israel has never agreed to return to the legal borders. Never.  The Israeli Foriegn Minister and negotiator  at the Camp David talks, Schlomo Ben Ai, has publicly stated that if he were Palestinian he would have rejected the Israeli offer.  Since Camp David the Israelis have never agreed to return to the legal borders, or even close to those borders.  The claim that the Palestinians are rejectionist when it comesto peace is pure fabrication.
