The pressure and challenges Obama faces in this summit cannot be readily resolved, and thus the summit will be a disappointment to Americans and the rest of the world.
Arabs are not going to normalize their relationships with Israel before recognizing an independent Palestinian state. That is what should be perceived by Netanyahu and supported by President Obama!
Obama has clearly stated that he supports total nuclear disarmament. However, this is merely a distant goal, so distant that the president himself has said that he does not believe he will achieve it during his presidency.
