And how do you purpose that we do that?

Certainly the "solution" to that problem isn't "showing ID" or bringing around proof of citizenship as the member I was responding was suggesting. No one's ID says "terrorist" or "not a terrorist" on it. And country of citizenship doesn't determine whether you're a terrorist or not.

It may not be the single determinant, but...........

Were FDR & Co. rounding up Irish Catholics during WWII?

By ignoring the brutal truth (country of origin and citizenship status) of who we (U.S.A. and a few allies) are fighting against, a dangerous confusion is generated that will only lead to unnecessary deaths and a prolongation of the war.

OK, so what are you proposing we do?

No, but they were rounding up tens of thousands of innocent Japanese, something that most people condemn quite strongly these days.

So what are you proposing we do?

And how does your plan address American/European citizens who are also threats (e.g. the second most recent and serious terrorist attack - OKC)?

Also, how do you respond to the reports showing that Osama style extremism is gaining ground among whites?

One modest, rather non-intrusive proposal would be to pay particular attention to people who have been to certain Mid-east countries that have a track history of supporting Islamic extremism. Travel to and back from such countries is a concrete fact that often correlates with increased risk. This sort of factor would be preferable to SSSS searches of American citizens on domestic flights, and would be much more likely to find someone who is a danger than the current system.

FWIW, rounding up Japanese-Americans and imprisoning them in the American version of concentration camps was horribly wrong.

OK, so let's say that you, I'm assuming an American citizen, have a history of traveling to (for example) Egypt, Saudi Arabia and Pakistan.

Now you show up for your flight from St. Louis to Des Moines.

Now what? SSSS searches are no good - you said yourself that even a pencil in the right hands could be deadly. What's the other alternative? Permanent no-fly?
