I think that his assertions that there was something -- or his assertion that there was something we could have done to prevent the September 11th attacks from happening is deeply irresponsible, it's offensive, and it's flat-out false.
I really hope that isn't true, and nor do I believe it is. I thought the whole point of the "war on terra" was that, you know, maybe there is something we can do/should have done differently. I really would hope that there was something we could have done to prevent the September 11th attacks from happening, and that there's something we can do to prevent future attacks.
Saying that isn't necessarily saying that they should have known what those things were, but even with what we know for certain plenty of heads should have rolled and it's unfathomable that they didn't.
