Between the US, Israel and the PA, some common definition of "talks" is needed. It clearly has different meanings to all three parties, but mostly to Netanyahu and the Israeli government. The "talks" are supposed to be negotiations, not where Israel dictates and everybody else jumps. Israel refusing to even recognize that Palestinians have made huge concessions on land is counterproductive, as intended by Netanyahu.
