I believe the United States would be a good candidate to help assist in mediating negotiations for a resolution. There is no other Arab nation that will help mediate without consequences if the negotiations are too favorable for the nation of Israel.
I admire how certain policy leaders have spoken for Israel and I believe that if we had a leader similar to Obama, then i would not believe the United States would be a good candidate for negotiations. It depends on who is leading our country and their team. If there is a Leader like him, who left our country and the world at total risk like they did with the Iran deal. I would hope we would not be in the room helping mediate. I am grateful for the time President Trump was in office, we saw many positive changes in the american voice on the topic of Israel. We even saw the true natures and opinions of some congressional officials. I think really the answer to the question above depends on who is the sitting president and who is on their team.
