By any reasonable standard, this is not news, although it perhaps does point to what to expect if such an attack ever does happen.
In a Creators Syndicate column from Tuesday, David Limbaugh expresses the common view that the U.S. had no reason to think it could face an attack before September 11, 2001. "The Sept. 11 massacres jolted us into the reality that we are not invulnerable to attack on our own land despite our status as the world's lone superpower."
I feel bad for any adult who actually didn't realize before September 11, 2001 that the U.S. was vulnerable to attacks or that there might be some people who, for some reason or another, would want to target Uncle Sam. Most who use this type of rhetoric, I suspect, don't believe it, but those who do were ignorant and/or not very intelligent, qualities that I doubt have changed very much.
If the U.S. is hit with biological or chemical weapons, I fully expect to read stuff like, "September 11 should have alerted us to the fact that America faces dangers. It is most unfortunate that it in fact took a second attack to show just how much the terrorists hate freedom. We owe to the memories of all Americans struck down by the forces of evil to never let this happen again.
