On the issue of corona virus which is alleged to be bio-engineered for offensive use, its ramifications should be taken very seriously I believe its high time to rethink on offensive biological warfare program as a deterrence or as analogue to Russian 'dead hand' fail-deadly & mutual assured destruction deterrence.
IMO nuclear weapons cannot guarantee protection against biological weapons because there will be literally no survivors if a country comes under biological attack.
Even if India is hit with 200 nukes there will be many survivors, with biological weapons literally no survivors over a period of time.
Eg if 1 kg of highly refined botulinum toxin is released & dispersed evenly by wind in all directions it is more than enough to kill 1 billion people if breathed in by them.
AFAIK bio-warfare agents have a pre-engineered oxidation life. Eg say botulinum toxin has been engineered to have a oxidation life of 72 hours
It means it will stay virulent for 72 hours & will kill everything within that time period after which it will lose virulence High possibility local mutations might occur leading to continued virulence in few effected areas, but a sensible country will never develop a deadly biological agent without simultaneously developing an antidote for the same to cater for own safety & unforseen complications during possible use, unless they are as dumbfucks as who you know
I have a suspicion that after what happened last year many countries have resumed their dormant programs relating to the same
