Howdy Indrajaya; You asked, "How many thousands square miles of palestinians lands been stolen during that times." About one sixth of a thousand square miles if you count the seamline area and East Jerusalem. However, who says that it is "stolen" Palestinian land? Depending on where the border winds up being, it could be land reclaimed and liberated from Jordanian occupation. I am unaware of any privately owned Palestinian land east of the Green Line which has been confiscated although some of it has been legally purchased or requisitioned with compensation at fair market value. Most of it was public land to begin with and was not privately owned by anybody.
