Have any Arab/Muslim countries gave a tribute to the victims of 9/11? These extremist groups continue to flourish because moderate muslims basically turn a blind eye to what they do. That is like a person who is witnessing a murder outside thier window looks down and does nothing because they don't want to get involved.
IMO they could care less about the USA because they ALL hate Israel and since the USA is a friend to Israel they
turn the other cheek to terrorist acts.
Maybe we will end up being like Israel when it comes to fighting Islamic terrorism, fighting forever until the Good Lord intervenes.
