I believe they are. If there is a simultaneous terrorist attack (like 09/11 or worse, like nuclear) on even six major cities in the USA, that could be the end of our nation as we know it. The economy would be ruined, there would be an enormous loss of life, and there isn't enough national treasury or military presence or human resources to simultaneously keep law and order and tend to search, rescue, and human needs of water, food, and medicine, and hazmat precautions in all the areas affected. We will be reduced to a third world nation. I believe there are serious flaws in the response to Katrina at all levels of government. And I believe the terrorists are watching all of this with glee and taking notes. The Nation of Islam is already trying to recruit street gangs to join the jihad against the police in Los Angeles. This is a movement that may spread like wildfire, especially among thugs and those who resist authority. I believe 09/11 was a wakeup call to America. Now I believe Katrina may be a glimpse of what is in store for us in the not too distant future. God, in His mercy may spare His own people, those who are born again. Then again, if He chooses not to, are we prepared for what may happen? Torture and murder and persecution to Christians goes on all over the globe. Why should American Christians escape the sword?
