Well, I'm worried about it. I think it is foolish to underestimate a threat like this. To take it seriously, and it doesn't happen, that is one thing. To blow it off but it turns out to be real, and they really did tell you, THAT is stupid.
I'm afraid I agree with you.
I still remember hearing about threats of a big attack within the US before 9/11/01.
Don't be paranoid, but always be prepared. And it would help if some of our leaders took this seriously as well.
