Here is noted neocon and Ukraine hawk Victoria Nuland's testimony confirming the existence biolabs in Ukraine and expressing concern for their integrity:

"I only have a minute left. Let me ask you, does Ukraine have
chemical or biological weapons?
Ms. NULAND. Ukraine has biological research facilities which, in
fact, we are now quite concerned Russian troops, Russian forces,
may be seeking to gain control of.
We are working with the Ukrainians on how they can prevent
any of those research materials from falling into the hands of Rus-
sian forces should they approach.
Senator RUBIO. I am sure you are aware that the Russian propa-
ganda groups are already putting out there all kinds of information
about how they have uncovered a plot by the Ukrainians to release
biological weapons in the country and with NATO’s coordination.
If there is a biological or chemical weapon incident or attack in-
side of Ukraine, is there any doubt in your mind that 100 percent
it would be the Russians that would be behind it?
Ms. NULAND. There is no doubt in my mind, Senator, and it is
classic Russian technique to blame on the other guy what they are
planning to do themselves."

You are simply arguing my point but seemingly unable to understand it. The point is that "biolabs" in Ukraine are inevitably conducting bioweapons research by any other name. Surely you would by now acknowledge that the Wuhan biolab was also conducting research of this kind and has been revealed to be funded by USAID via EcoHealth Alliance. This was obvious back in 2020 if you already understood how these investments work. You're 100% wrong to say no facts support it, but leaving that aside, there are standards of evidence that may not amount to the "smoking gun" proof you seem to be calling for. I don't know why such a thing is so inconceivable to some people. History is replete with examples of states doing such things under the radar. In this case, there is "a preponderance of evidence" (yes, some of it "circumstantial evidence") that Wuhan Lab was conducting what used to be called "gain of function" research. (Go ahead and quibble over meaningless distinctions, I'll wait.) The stated goal is to develop vaccines for possible zoonotic diseases. But in fact what happens is that zoonotic diseases are postulated theoretically and developed in anticipation of their appearance in the wild. In fact, these Dr. Moreaus go beyond the physically likely and create all kinds of freaks and chimeras in the lab that are, surprisingly, tailor-made to harm humans. But of course, it's all for vaccine development and biosafety. Only an idiot would accept that explanation after reviewing the network of funding and secrecy surrounding these labs. "Russian scientists...have accused..." as if I can't find you American scientists at the highest level of government who have accused such trivial plausible or even likely explanations as conspiracy theory. Turns out some of those scientists were involved in cover-ups and personal financial gains off the research. You seem very ready to condemn Russian propaganda but equally eager to accept Western propaganda. Why not maintain an equal healthy skepticism of both?
