There are reasons why the political Left has been accused of being unhelpful in the Middle East peace process and why some argue an underlying antisemitism is at play.
It is only possible to reach a lasting peace if both sides are willing. Palestinians are willing - are Israelis? I see the internationally illegal colonies being constructed in the Golan Heights and Hebron and have my doubts.
also, based on what you say that palestinians are willing to reach lasting peace ?
