This is reminding me of the movie Arlington Road already.
The people are trying to find someone to blame so they can retaliate and kill lots more innocent people just so they can get their revenge. I forget which country is getting pinned with the blame right now, but I highly doubt they did it. You don't need a country to do this, just a small group of mildly intelligent people.
But we're going to blame them anyway, because we NEED to blame someone, and we NEED to get revenge, which, if it's war against a country, is only going to amount to killing a bunch of innocent people who had nothing to do with the decision, EVEN IF a certain country's leader DID do it.
And regardless of whether they did or didn't do it, our eyes are focused on them now, and if they even sneeze wrong, we'll have 'proven' that they did it and go to war with them.
It doesn't help that Russia and China are allied against us already as it is for starting that stupid 'Star Wars' program. They'll probably jump on the chance to gang up on the US. We may be powerful, but we're not all-powerful, and that was proven today.
I almost wish that World War III did start because of this, and 99% of the species was wiped out and the planet reset, so maybe finally we'd get our heads screwed on right. It's pretty stupid to start a war over something that you cannot undeniably prove who did it. As far as we know, the only people who were behind the whole attack died in those planes.
I think if the US is to learn anything out of this, it should be that security at the airports should be tightened somehow, and understand that bad things don't just happen overseas, it can happen here as well. And that it can happen to you. Beyond that, I don't think there should be such a stir about it.
