Good point. A communicable bioweapon constitues a permanent threat across all human territories. Anyone would be justified in destroying such facilities at any time via defensive coercion. The harder task is to learn of their existence with enough surety to justify such actions as reasonable.
Ideally you’d want a small and highly trained covert unit.
I think future libertarian societies will have such units to accomplish things like this, voluntarily funded, and tasked with freeing slaves, taking out existential threats like bioweapons, and perhaps even being proactive in nuke detection so as to stave off that threat.
I was reading the LIbertarian Forum recently, from way back. The first issue mentions something about ad hoc world-courts in essence, private citizens getting together and passing judgment on the sovereign use of power and the like, as a way of bringing pressure on regimes.
I think if a protective agency discovered someone building bioweapons, they could go public, construct an ad hoc court or contract with an arbitrative court, seek a conviction in absentia, and then take donations to destroy the facility/bioweapon as constituting imminent threat of harm to every human being.
Now, there is a moderating factor. Bioweapons aren’t actually designed to be communicable. Thus I don’t think any exsit that would be deployed that are actually designed to wipe 90% of the human race off the map, such as a weaponized smallpox could do. Rather, when you weaponize a virus you seek to limit its ability to infect, elsewise it would infect your own people.
This is why anthrax was an effective bioweapon, it’s not communicable at all, you have to breath it in. Similarly, I think a weaponized smallpox would likely have any infectability stripped out of it at the genetic level. You breathe it in you’re infected, but you cannot spread it. Dunno if that’s what the Russians were able to do or not, but that’s what would make sense.
At that point, all you have to worry about are nihilistic environmentalist terrorists, ala the 12 Monkeys scenario, where humans create a virus specifically in order to wipe out humanity, out of beliefs stemming from radical environmentalism that values the existence of animals and the planet higher than human lives, people who believe the ideal is to reduce human population to half a million lives or so, and such people might rely on natural resistances to do so.
Another more dangerous form of bioweapon is one that contains triggers in the presence or lack of certain racial alleles. This means scientists would try to make a virus that would only kill certain racial groups, or fail to kill a certain one. This is the holy grail of certain racialist ideologies, such as pan-arabism.
Such a virus is the root conflict of a certain novel I’m working on
