I noticed the Olympics went by without incident. A very large dog did nothing in the nightime.

While it might be difficult to repeat a massive 9/11 type of attack, it would be impossible to defend America against the type of attacks going on in Israel, and in Russia. Where have they been?

Why hasn't a mall been blown up? A bus? A subway? Why are no schools attacked in America?

Just sitting here, I can think of a couple of ways to take out a bunch of American citizens without leaving a paper trail, or being in any way detectable until the attack takes place. No explosives. No weapons. Nothing.

Have the terrorists decided that only a big attack is worth it? Doesn't that imply a vertical level of organization that is not supposed to be there?

There is a theory that covers this, but I have no evidence to support it other than the quiet. Will post it separately.
