Not gonna mention that 15 of 19 were Saudis -- NOT courtesy of "Western" nations,

Guess again, they came to other western nations before coming to America. They'd be subject to more scrutiny coming direct from Saudi or Egypt.

however, they could just as well have brought in a small army through the southwest border, aka The Securty Sieve

And they opt to not do so for specific reasons that actually make sense.
