We need to adapt El Al’s security measures which were bandied about after 9-11 and promptly forgotten. They include such things as:
profiling by religion,
looking at recent travel history,
checking passport and name against multiple data bases,
multiple screenings of luggage,
luggage not left unattended once screened,
intense inspection of passports and boarding passes,
sky marshals on every plane,
double doors on all cockpits,
pilots are allowed to armed in cockpits, and
interviews by security officers prior to boarding.
Even at overseas airports El Al conducts security checks even if they are supervised by government or private security firms.

I agree. El Al is the gold standard of airline security.
The only reason the US doesn’t emulate them is pure PC crap and nothing else.
