If forced to answer the same question that was posed to TT they know full well they can't just repeat the same tired old "we'd bring the terrorists responsible to justice." That won't wash after a nuke attack on American soil that racks up casualty figures in the hundreds of thousands (at least).
It's easy to say we'd sniff out the nation(s) responsible for helping out the terrorist org in question and then annihilate them (although many would still be reluctant to publicly say it), but there's a distinct possibility that the nuke(s) wouldn't have a return address. Then what?
The answer: Adios Mecca.
The whole thing illustrates just how boxed in we are with political correctness. We can't go and annihilate any country that would have had a hand in this nuke business because it would be like "Dresden" and we are supposed to be ashamed of Dresden. We can't purge the profile from the homeland so as to avoid the disaster for which we can't respond because that would be "ethnic cleansing" like Milosevic's actions that caused us to go to war against him or the Japanese internment camps during WW2 and we all know we are supposed to be horrified by those things.
They can't criticize Tancredo for long without having to answer some questions themselves and that is when they will wish they never criticized his remarks. I hope that this controversy doesn't fade away anytime soon.
