Because under Secretary of State Victoria NNuland, you and OANN have embraced the most extreme nutbaggery.
No one in that article admits to "bioweapons labs" or creating any type of bioweapons.
Russians are accusing the United States of essentially creating Covid19, experimenting with "ethnic viruses", and creating viruses to unleash on Russia using fleas, birds, or other fantastical means.
There is no evidence for any of us and it is also retarded to even entertain.
Nobody sees Putin as the good guy in all of this, but that doesn't mean we don't have biological labs there. We'll need to wait and see.
