-a wave of concern crossed the Atlantic and sprinkled the American shore: Could something like that happen here, too?-
Gosh, COULD something happen? Ya mean OTHER than OKC and 2 "tragic events" at the WTC? And who knows how many other incidences not released to the public?
None of the 9/11 hijackers were permanent residents. If anything, the whole experience demonstrated that Middle-Easterners in general and Saudi Arabians in particular are poor houseguests who should not be allowed admittance.
It's long overdue to reconsider the concept of the United Nations staff being allowed to run loose!
Even if it were true that we aren't creating jihadis, we're still importing them all the time. As the tread about the 2007 immigration lottery showed the other day, the elgible nations are predominantly muslim + france and germany.
We're commiting national suicide.
