It appears to me that the genie is out of the bottle. Obviously no American president can withstand the vaporizing of NYC and tens of millions of Americans. Something will have to be done to respond in kind. You can be sure that there are plans for such contingencies or there had better be.
Perhaps nuking the Afghan/Pakistan border area where Bin Laden is hiding. Of course there are 2 problems with this:
1. We'd be relying on our famously unreliable intellegence community and more importantly
2. Pakistan has the bomb too.
There are no easy solutions.
I feel bad for Tancredo putting himself in the position he did, if he has stayed away from Paul Williams, the kooky moonbat who wrote "Inside the Vatican" he'd never have got the now infamous question as he would not have been on that call in show.
Yes, there had better be a response. And we know now over half of the right prefers a politically correct response.
