September 11: Have we learned anything yet?

Answer: Well, sort of.
Our border security is still a joke.
And a sizable chunk of the country still doesn't get that this is a war, not a police action.
Also, that sizable chunk doesn't get that this enemy is extremely patient. This is not Law and Order, folks, where the perpetrator is captured in 22 minutes, then put on trial in the next 22.
One thing we have learned is the depth of anti-Americanism -- right here in this country.
Not a good lesson to learn, eh?
