I think we need a Hiroshima before we wake up. Even then, the jury is still out.
I hate to say this, because I don't want to appear to be wishing it on anyone.
But our best "hope" is that the wake up call - happens overseas - the UK, Europe, Israel. Rather then it happening inside the US first. even the american media would have to cover a dirty bomb or nerve gas, taking out a piece of London or Tel Aviv.
I mean, it would have to be a 3 day story for them at least, wouldn't it?
