Since the events of 9/11/2001, the highjacking (with the help of fraudulently obtained driver licenses) of four US domestic flight jet aircraft to be used as Kamikaze flying jet fuel bombs to crash into their targets we (the US) have developed the (WHTI) Western Hemisphere Travel Initiative the corner stone of which is the national standard of obtaining state issued driver licenses “REAL ID” with the required “proofs” documentation standards.
The REAL ID with a star () indicator on your DL is still only voluntary vs. mandatory as it’s full implementation has been repeatedly postponed.
So, we have a mix of DL IDs still with many standard, not REAL ID DL that are NOT for Federal Purposes, like passing TSA checkpoints at airports, but the standard DLs are of the harder to obtain, just lacking the birth certificate requirement of proving citizenship.
So, boarding airlines is still harder for foreigners. What are still too easy to get surface transportation especially rental by remote apps. vs. in person if one has even just a standard DL, and credit card accepted by the rental companies.
So, if terrorists are grounded they just switch to surface transportation to facilitate their eval deeds by recruiting US citizens with the ID and credit card(s) needed for their oneway rides to hell taking as many innocent lives as they can in the process.
The US authorities have tightened up air travel with the TSA.
I don’t know what they might be able to do to tighten up surface transportation especially from domestic U.S. citizens recruited to usurp the ID/credit card requirements of renting vehicles to be used as weapons.
That’s another security challenge.
Especially, when we have so many upcoming and already graduated indoctrinated individuals sympathetic to foreign causes, and entities that wish us ill.
Witness all the antisemitic / pro-Palestinian protesters that surfaced on our college campuses this past year.
We have real national and personal security problems just ripening to happen.
Whole segments of our society readily agreeable to be inspired, or radicalized, and volunteer to do evil for our sworn enemies.
We unfortunately are likely to see more, not less of these incidents.
What that means is, now more than ever our situational awareness, and preparedness needs to be strengthened to levels previously not necessary as these types of threats become more prevalent.
