Regarding the Bioweapons MAD point: I think detecting that a novel bioweapon has been deployed might be less trivial than you think.
A (possibly) more serious problem is identifying who deployed the bioweapon: it’s easy to tell from where land based missiles come from, but much harder to verify that the weird symptoms reported in one part of the country come from a weapon from this specific adversary.
