Just because someone is "Arab" that does not necessarily mean he or she will be pro-Muslim. Many Arabs are Christians, particularly Arab-Americans who descended from parents and grandparents who were running from Muslim persecution in their old countries. I myself am one such American. I am half Lebanese. My father's maternal grandfather and my father's father immigrated here from what was then Syrian Beirut. They were both Christians.
The list of Arab Americans on the Wikipedia link includes quite a few who were born Christians, including Steve Jobs, Ralph Nader, Donna Shalala, Marlo Thomas, etc. Regrettably, quite a few Lebanese are liberals, including in my own family. But they are not Muslims by any means.
The difference between the Lebanese and the Israelis is that the Lebanese have tended to negotiate with the pirates, whereas the Israelis have resisted them. Both strategies have their advantages and disadvantages. But neither has been decisive, at least so far.
