Why would the Palestinians or anyone else besides the Israelis be confident in Obama or the USA at all? America supports Israel in what ever Israel does, maily committing crimes against the Palestinian people and international crimes as well. America uses it's veto powers to crush any attempt to punish Israel for it's crimes and yet, always condemns other nations for committing the same crimes Israel does. America has shown nothing but support for terrorist dictators and governments in the past and present and there should be no surprize as to why most around the world do not trust America for anything.
