Seriously? That would be difficult, since Ukraine gave all its Soviet era nuclear, chemical and biological weapons over 20 years ago.
As for those "top secret" bio labs. Those are part of a publicly known, 30 year old program few paid attention to until someone on twitter got hysterical. Those are BSL-3 labs, anything thy have can be handled by cooking in a autoclave or with bleach.
Right...and Iran doesn't have uranium and Fauxi didn't create a bio-weapon in Wuhan.
