The enemy is not a small group of individuals within a peaceful sect, it is Islam itself. Unless we remove them from our midst, we can never win. It is probably not possible to do this, so I guess we put up with terrorist attacks here at home indefinitely.
If the premise of the article is correct, that the followers of the Koran will not assimilate, then we have a malignancy within the body of America. Without surgery, the country as we know it will perish.
The politicians will not do anything but call for stricter laws, and more suspensions of the constitution. This will eventually lead to a fifth column of those who are traditionaly wary of govt power to rise up against this govt, and begin terrorist attacks of their own. IMHO if the govt does not at least excise the cancer within, and that includes all illegals, things can only get worse.
It is beginning to look like one of the things that will come from this is a form of national ID, the religious will fight it, but it looks to be inevitable. It would be a logical step, and could be a useful tool to identify those not legally here. I hate to see it, but one more atrocity committed against the nation, and people will scream for something to be done, and that is the next step for those that have planned for this eventuality.
