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.
