At what point do other nations at the UN say fuck what the US says, we will take care of it ourselves?
Never. Countries act in their own interests, not for the good of humanity (beyond easy missle strikes against non-aligned militias, as in Kosovo, or on-paper condemnations).
Even in the neighborhood, although Saudi Arabia and Egypt (et al) support symbolic measures for Palestinian human rights, both are strongly allied with Israel. The Iran-Russia block would do something, perhaps, if Israel didn't have nukes and US support.
