One also should take the ethical consideration of deploying a bio weapon into consideration. The world has moved beyond realpolitik and the age old "might makes right" attitude, to use biological warfare in an unethical manner would result in condemnation from the international community.
I so wish that to be true, but if Ukraine proved anything, it is exactly that might is right is alive is well ( for example, Germany only buckled after nordstream blew up or India just saying no to US restrictions on gas purchases ).
