What Went Wrong?

This article written by Bernard Lewis explores present day issues involving Muslims and his perspective of what he thinks went wrong. As I was reading this article the tensions between Muslims and Jews was really put into perspective for me. One question I have is: is Muslims and Christians worked cohesively to oppress the Jews, than why do we often see them battling heads? I feel that all three of the religions mentioned in this article have more in common than they think. Not to say that they are the same, but some aspects are similar. Another thought that comes to mind is: Is the US fueling the fire in the conflict between Palestine and Israel?
