What I am saying is he knows what we are funding and he would know about our labs. Even if he never visited one of these labs personally he would certainly be able to speak on behalf of those that were there and did. He oversees our funding of biological research. He would be a very strong voice for those in the know to respond to the Russian claims.
Russia has made very public claims to the entire world of the US being involved in war crimes concerning bioweapons. Who is coming forward and denying it?
The US ambassador to the UN refused to respond to those allegations instead attacking Russia's credibility instead of forcefully denying the claims. Fauci has disappeared. The only high level person to address this has tippy toed around the fact that yes, we do have bioweapons labs and research in the Ukraine and yes, the DOD is very worried about these falling into the hands of the Russians.
You've made several formal logical fallacies here.
First, "silence" is NOT an admission of guilt. This is a big mistake far too many people make (most notably regarding our justice system.)
Secondly, just because Fauci is the leading virologist and spoke on behalf of NIH during the coronavirus crisis, does not mean he is privy to investments in foreign countries and their health systems.
Third, your entire position is based completely on confirmation bias. You've come to a conclusion, without any evidence to back it up. Instead, you are reaching for evidence to shape towards your conclusion.
Russia has constantly been lying to the entire world ever since at least before their invasion to take Crimea. They said that's all they wanted. They lied about not invading Ukraine when they were massing their armies on it's border. They lied to their own people that they weren't going to war. They lied about Nazis being in leadership positions in Ukraine. Nothing but lies. Not a very good track record there.
