Is the US not making any demands of Israel because it would be emabarassed by Israel since it knows Israel would just refuse and speed up their colonialist endeavour? How can you negotiate over what is no longer there? This ongoing stalmate has little to do with the Palestinians and everything to do with Israel violation of international law and domestic concerns in the US that holding Israel to account is not possible. Kerry will fail as have his predecessors and Israel will go on taking more land and blaming the Palestinians which the US seems to be doing as well.
