One needs to read between the lines. No Palestinian leader can give up the right of "return". The Palestinian problem is two fold, the ones who live within the WB and Gaza and the millions who live in the diaspora. Both must be resolved, half solutions are no solutions. By insisting on the right of return, the Palestinian leadership resolves the entire conflict. The Palestinian leadership according to leaked documents already agreed to a token and symbolic return of few thousands with fair compensations for the rest. Money can solve a lot of problems including this one. Many countries will be happy to pay their share of the compensation to bring this conflict to an end. Israel refuses the right of return on principal, because it means, it admits that it displaced the Palestinians out of their homes in 1948.
