Our current government can't even monitor for screwworm, measles, and salads.

You think they can successfully track the smartest and most individually dangerous citizens, who have been previously vetted, and work inside the system already?

Let's be careful to separate capable-of from motivated-to.

Those three "can't even monitor" situations can be traced to blocs with both (A) a financial profit if they succeed and (B) some non-clandestine political clout to sabotage/discontinue things.
