Are the threat warnings any more irresponsible than the people dismissing threat warnings as "politically motivated"? If we stop the terrorists, they call it political grandstanding. If we don't, people die and they demand inquiries into what went wrong.
As far as the liberals are concerned, it's damned if you do and damned if you don't - so **** 'em. We're just going to do the right thing and try to ignore you quivering ninnies.
