The duplicity of the US and its one sided, actually only focus on Israel prevents the US from ever being an honest broker. Turkey, Egypt and the Palestinians must of necessity ask what advantage is the US seeking for Israel in such meetings. The only border that can even begin to provide semblance of justice to the Palestinians is the 1948 border, no other, but sadly this will never be what the US and Israel allows. Besides Palestine will never be allowed to be an independent country with an independent foreign policy, with w defence capacity to address any foreign power ( maybe Palestine will need a nuclear deterrence in keeping with its neighbour Israel's capacity to deter!!! ) Remember Israel is demanding secure security. This must be available to Palestine as well.
