Vast majority of Americans do not understand the enemy or what motivates them to do what they do. One would need to have some good Muslim friends to get an insight into their way of thinking. Most do not have any. This one does have some understanding of underlying reasons for what is happening, but when he questioned something the rest ganged up on his suggesting he was an anti-semite.
Americans will continue to follow the polices that failed for decades and some of them will end up paying the ultimate price. It is almost cruel to send them there saying that they will be bringing peace, stability, freedom and democracy to the middle easterners. Even here where they were born they can not defend themselves because their government does not trust them. In the end it might not have made the outcome any different, but at least the rest could have little piece of mind that they did not fall defenseless. The least the leadership could do is tell them the truth.
