1 Those labs are also an existential threat to the United States. They take viruses which are not lethal, which will at worst make people take four days off from work, and develop them to be more contagious and in fact lethal, so that more people will get sick and many people will die. That's what "gain of function" is. They are the United States developing biological warfare. They are the United States creating weapons of mass destruction. Those labs are in Ukraine because the government does not dare to situate them in any friendly country, let alone in the US. They are a horror which are beyond belief.

2 Amen to that Bill! In fact it was Richard Nixon who, upon learning what we had been doing with such viruses,  completely banned all work on biological weapons. The national security apparatus simply outsourced the weapons development to avoid that pesky thing called U.S. law. 
They really are a horror and something that could in fact wipe out the whole human race. I rarely say such things but I do when it comes to biological weapons; some madman could easily create a disease that would be lethal to almost all humans. It's absolute madness.
