What are you talking about? There have been 5 (five) cases of screwworm in the us and the us is responding by producing millions of sterile male screwworms a day as we speak.
You're right about the countermeasures, but I can't help but look at 1971 (473 confirmed cases, then almost 100,000 the next year).
Basically shocking levels of incompetence; start an unpopular war, lowest approval ratings of any president ever, pardon J6 traitors, $6/gallon diesel levels of incompetence.
