The problem with the pathogen being released in Russia , I think, is this. If it is just the original Black Plague that is one thing and that is bad enough. But if it is the Black Plague that has been accelerated as a weapon by having its DNA changed as Covid was and has been released intentionally, (as Covid was in China) that is quite another. Time will tell.
If (and there are a lot of ‘if’s’) it has such a high mortality rate and such a short incubation period, it more resembles Ebola and will be containable. With the help of God… The horror of it is that its properties, if true, indicate a weapon deliberately designed for short-term mass death in a target area. Absolutely the work of the devil, but the same applies to nuclear weapons. They are all primarily directed at non-combatants, with no regard to age or sex.
