1. Do they come down when we defeat Al Qeada, or will we elevate some other group to their status to justify it?
We will never defeat Al Qeada..that's the
point.

2. When was the last major terrorist attack against a monument, like the Washington or Lincoln Memorials, where there are likely to be few casualties?
That statement proves the terrorists have
lulled you into a false sense of security!!!

3. How do metal detectors stop planes from flying into buildings?
Simple: it creates an environment making
everything more difficult for everyone,
including terrorists who don't ever have to
enter said environment. This also depends on
your definition of "stop."
