No adversary, or group of adversaries, in the real world exists in isolation. Humans will take advantage of viruses, viruses will take advantage of humans, as in the case of toxoplasmosis gondii.
In other words, all possible threats, are co-determinants to varying degrees, of the real threat faced by actual humans. Even those without intelligent agency.
So this assumption would quickly breakdown outside a fantasy world.
