I think yes and no to this question. It depends on the current leadership and the foreign policy application at the time of mediation. It seems that the mediation technique changes every 2-4 years and is dependent on the political pendulum. I feel the United States has the potential to mediate in the most powerful way, but I do not trust our leaders to mediate in the right way. It seems that for every zionist there are three anti-semites waiting to pounce at the first discussion about Israeli-Palestinian relations.
