My point was it is not necessary to just kill the enemy. Incapacitate the enemy with a tsunami of infrastructure failure. Hospitals pouring out into the streets is the least of it. If there is no effective containment, think of half of the work force quarantined ... half the military ... half of the government ... work stoppages ... logistics failures ... food shortages.

And the point of the attack would not be to conquer a country outright, but to cripple it. Think of repeated attacks.

We are obviously not prepared for such a scenario, and I am not sure if there could be a viable program developed which would address such low probability scenarios ... just spitballing

Far fetched? maybe ... but if I thought of it (or maybe I am channeling the movie "Outbreak" where the US military was the bad guy), I know there are some very cleaver bad folks thinking of it

ignorance is the enemy
without equality there is no liberty
America can survive bad policy, but not destruction of our Democratic institutions
