Personally, the prospect of seeing our major cities nuked to dust is less frightening and disgusting to me than the prospect of concentration camps holding American citizens on American soil. In the first case, the country may or may not survive in some fashion. In the second case, the country--my country, embodied by the Constitution--is already dead. And even those camps wouldn't stop the nukes in any case.
What can I add to that?
It's a good thing that Hitler did not have the idea of sending over SS and Luftwaffe "students" in the 1930s, you would have given them directions on their way to their targets.
The first statement is incomprehensible. Given the scenario of suitcase nukes and given the provability of an Arab Islamic connection it is then necessary to consider solutions as extreme as the effects. In this respect, your notion of the Constitution is to absolutize the rights. This is not even a principle of interpretation of the Constitution. All the rights are conditioned. When you've had a pattern of connection and it has been otherwise impossible to route out the perpetrators the only solution is internment. You can guarantee all their assests, their jobs, and make it nice and comfortable for them. Big screen TV's, Kentucky Fried Chicken and caviar, etc.
This collectivization would give the government the opportunity to separately consider and screen the individuals in this community.
Such a process would only occur if the perpetrators were citizens/citizens gave the perpetrators aid and succor.
All this of course is highly speculative but you make it seem that the Constitution is some rigid document and could not countenance the scenario above. A similar scenario under less extreme circumstances took place in WWII with the Japanese and the Constitution still stands with even a more broadening of rights since that time.
