Not necessarily. Why just set off one nuke in a mall in Nebraska. You get more bang for your buck if you use several in many places at one time. Greater attention to the act, hurt the economy worse, etc. As for 5,000 cells, that would not surprise me in the least bit. There are over 11 million illegal aliens in this country now. Millions more that came here legally that may not just be here to be future Americans, but rather here to kill a few thousand of us. Look have they have swarmed into Europe. They are doing it here. If you refuse to see that, you are making a mistake. The bad guys are here. They intend to do harm. Count on it big time. We are not "SAFE" from an attack within.
Thanks, I'll keep an eye out for Pancho the terrorist dishwasher the next time I'm in the US.
