Regardless of the people who want peace, regardless of their religious beliefs or no religious beliefs, use of the sword brings only more use of the sword. And, that sword swings both ways.
Another attack upon the United States will bring things to the Muslims that they don't want. There would be no way to stop it. There are Muslims who will not try to bring peace between the East and West. Their religion does not permit them to join the infidels in stopping the "warriors" among them.
If I were a Muslim, I think that I would be very afraid of what the extremists do. When the backlash begins, there would be no way to separate the peaceful Muslims from the supporters of violence. And, there would be a backlash such as not seen before, if the extremists explode one nuke, regardless of size, or use bio/chem weapons in the US.
We can talk peace and understanding, but the end result of Muslim terrorism and use of the sword will only bring total war. And, it will be anything but pretty.
