I think thats what makes it so incidious. Becoming nationalistic is part of the NWO -- to a certain extent it involves being able to pinpoint and persecute those that are suspicious and might endanger the public. Question is -- how do you do that? Closing the borders is impossible...one terrorist that makes it through can kill 5000 people...
I'll add to that. The terrorists that did this had expired visas -- they should have been hunted down and removed anyway. I think these issues are going to take on a BIG role in future debates about our internal security. We will obviously look more like Israel after this. If you are in Israel you see people with M16s in the malls, at checkpoints, walking down the street, even driving between cities you'll see them up on the hills walking across border lines.
Its a free society -- I can walk around all I want because I don't look like an Arab. However -- you might occasionally be stopped and asked to prove your identity. Getting into the country is VERY easy -- getting OUT is extremely hard -- don't ask me...
They control their airspace and the airports are a considerable distance from the cities. They have marshals on every flights.
