You describe Obama's actions in a very naive fashion. It is not that he is ignorant of the history of the Middle East conflict. He, and his Secretary of State, know perfectly well the history of the area. However, read his speech in Cairo, watch the video of Hillary Clinton hugging and kissing Arafat's wife and of Obama bowing down like a pauper before the king of Saudi Arabia (who is a mere two steps removed from a tribal chieftan Ibn Saud) and then say Obama is acting from ignorance. He acts from hatred of Jews, fastered in his church of 20 years.
