Obama is seen as a muslim in Israel - not the standard white christian american they are used to. It makes them not trust him. Obama does not share the judeo-christian bond that jews rely on to influence US and EU leaders. He is just not "one of us" as far as most jews are concerned. Obama should try very hard to make jews comfortable with him, while advancing the US-Muslim relations in parallel.
