There is only one side to take. The “Palestinians” are not a valid “side”; they are the enemy of both Israel and the US.
Neither Oslo 1 or 2 are valid thanks to the actions of the “Palestinians” to breach them, including what they did in Area C where they are supposed to have zero presence and involvement, never mind the continuous “from the River (Jordan) to the (Mediterranean) Sea” rhetoric out of the Palestinian Authority.
Are the 14 countries on the U.N. Security Council that voted to condemn Israel for constructing settlements in the West Bank enemies of the U.S., too?
