I have my doubts.
I've been saying for a while now that it will take another 9/11-scale event, or worse, to *really* hurt Political Correctness (it's only been slightly stunned), and spur taking real action. And I'm very afraid "real action" might turn into really yanking rights of Americans to create a really locked-down police state.
We need to crunch the societies and ideology that have allowed this to occur. We need to crunch them like we crunched Germany and Japan (cities in ruins, societies on their knees, evil ideologies erased).
I, too, fear we haven't the will to inflict the required amount of pain in the face of international censure, but it is what is needed. We'll see which direction we're headed after the next 9/11-scale event.
