From the standpoint of a Middle Eastern citizen, Americans look like a bully forcing our way of life on the Islamic way of life. The notion of purity is very important in Islam, and a lot of the negative warlike actions taken against us have to do with our physical presence in the Middle East. Osama bin Laden was trying to get the American, or protesting the American military presence in Saudi Arabia. It's not surprising that our strong presence in Iraq has produced a wave of resistance anger, extreme anger in some cases, and a permissive atmosphere that allows these people to go undetected.
