I doubt that any of these will actually be asked to him today, because for some reason journalists are more polite to someone who pays terrorist salaries than to politicians of the party that they dislike, but here's my list:
Most Palestinians can trace their family trees a few centuries back, often to prominent families in Arabia. Is your family descended from the Banu Abbas family from the dawn of Islam?
Do you regard Jews who quietly walk on the Temple Mount to be desecrating the area? You referred to them as having "filthy feet," do you still think so? Do other non-Muslims who visit the site also desecrate it, or just Jews?
Do you believe that there is a Jewish people, or that it is merely a religion?
At the UN today, you showed a map that implied that Palestinians accepted compromise on the land in 1937 (Peel) and 1947 (UN.) Of course, Arabs rejected those plans. Why are you showing the world maps of "Palestinian compromise" that are clearly historically false? pic.twitter.com/cd5LquMXzI
Chaim Weizmann once said that he would accept a state the "size of a tablecloth." The Palestinian attitude seems exactly the opposite - you will NOT accept a state unless your laundry list of demands (Jerusalem, "Return," prisoners, borders) are exactly what you demand and nothing less. How much do you really want a state when you claim on the one hand that your people are suffering terribly but on the other hand you have demands that Israel can never accept?
Why should Israel trust that you are interested in peace when you and your government routinely praises terrorists like Dalal Mughrabi?
Given a choice of a true peace with Israel and unification with Hamas and Islamic Jihad while they remain armed and sworn to destroy Israel, which would you choose?
It's been over 25 years since Oslo. In all that time, you could have prepared a generation of children to live in peace with Israel. Instead, you teach them in schools and on TV that all of British Mandate Palestine is theirs, that they have a "right to return" to a state you consider your enemy, that martyrdom is their sincerest wish. If you want peace as you keep saying to diplomats and the Western media, why has nothing been done to actually teach peace with Israel to children?
And a few years ago I made a poster of lots of other questions for Abbas.
