So now the loonies are creeping out of the woodwork. You know, the ones who say "The US government actually staged these attacks, so that they can declare martial law." (Hello, look around, no martial law declared...) Or the ones saying "We should exterminate all Muslims." (Sure...and while we're at it, we should exterminate all Christians because of those looney-tunes who bomb women's clinics, right?)
And ultimately, besides killing a bunch of people, the attacks accomplished nothing. Buildings destroyed: 2. Lives lost: Several thousand and counting. Economic damage: $20 billion and counting. Effect on the US position as the dominant superpower in the world: A big, fat zero.
