You fail to realize two things: 1) The PA wants to continue the armed struggle to "liberate" Jaffa Akko Lod Ramle etc." 2) Lots of Jews living in the 50 miles between the Jordan river and the Mediterranean like to stay alive. So . . . If you and "the US, EU, Russia, the world etc." somehow force whoever is running the Israeli government to create the PA state in the West Bank, this territory WILL BE USED (make no mistake) to launch attacks on 9 mile wide Israel, as you will have given the PA the land they need to launch the Palestinian War of Independence. What happens next is blood on the hands of the peacemakers and statesmen, because the status quo, for all its flaws in better then the bloodbath a PA state will cause. Primum Non Nocere. Local "tribal and clan" rule by Palestinians in "the territories" with the IDF in charge of the 50 miles between the Jordan and the Med, was way better for all parties, including Palestinians, that what the post 1990 Peace Processes have wrought. I.E. a generation of Palestinians who think that blowing up Jewish babies in Sbarros is holy martyrom, according to PA TV, newspapers and leaders, who YOU peace processors have installed over the Palestinian people.
