> I know there is no handbook for peace
You mentioned Jerusalem. I'm Israeli, so I'm biased towards one side of the Jerusalem story but let me try to frame the other side of the story as to not play my biases. I probably won't be accurate because my propaganda is different from their propaganda. And I won't reply because this will otherwise turn into a flamewar real quick.
Does peace mean to you that the Palestinians stop fighting for a state of their own? They just raise their hands, lay down their guns, and embrace Jewish rule? Should they accept your $2 trillion - the number that you stated to invest in the peace project - as reparations for loosing their olive groves, villages, and roads to Israeli settlers? Will that be enough for them to embrace no public transportation on Saturdays, even though their culture would have it be Fridays? Will that be enough to forgive the years that cousin Ahmad sat in an Israeli prison? Will that be enough to forget the eye or leg or life that cousin Mahmaud lost?
And what of the five million people whose grandfathers either fled or were chased from Palestine in 1947? Should they accept some slice of the cash and relinquish their dream of returning to Palestine? Sure, some of them live in the US or Italy or the UK with their nice standard of living. But some of them live in refugee camps - to this day - in Lebanon and Syria and they have no rights in those countries. Under your peace plan, what becomes of a child in Yarmouk, whose family has been forbidden from education, health care, and most forms of work for three generations? Does he take that slice of $2 trillion and now buy a house in Syria? Forbidden to him. In the UK? He doesn't even qualify for a passport. In Palestine? Palestine has not enough land to quadruple its population. In Israel? To live under _their_ laws?!?!? What if Palestine and Israel are a single entity under this plan... does that make the situation easier or more difficult?
In my opinion, some problems just cannot be solved with money.
