The US funded former bio-labs and scientists all over the former Soviet Union to prevent any outbreaks of pathogens and to prevent the scientists there from hiring themselves out to others for bio-weapons research. Cool story bro...but there have been multiple deadly outbreaks near these US funded "research" facilities in recent years, and it doesn't take three decades years to clean up old Soviet laboratories. Also, the arch neo-liberal Victoria Nuland spilled the beans about these labs recently while testifying before the Senate Intelligence committee, and the Russians have shared incriminating documents they gained access to in Ukraine...so spare us the hasbara.
You people are as brain dead as the Left. It is, in fact, just about impossible to clean up some these sites because they leaked pathogens for decades. The best that can be done is dismantle the labs and close off the areas around them like Chernobyl. And even if the labs are closed, the scientists still have their knowledge, so it's probably a good idea to give them a paycheck lest they hire themselves out to Iran, North Korea or others.
If you believe anything the Russians are saying about Ukraine, you're a genuine imbecile.
