The US knowing the russians were going to invade, leaving a biolab up and intact? Ok sure, it should have been leveled, made a parking lot on day 1...I absolutely believe we're doing shady things in Ukraine just like in Wuhan, but I also believe this narrative is largely cope by the Russians. It's like the WMD Iraq narrative, only we made that story up ahead of the invasion and they seem to be trying to build it as their invasion falters.
Russia invaded to keep Ukraine away from NATO and/or for other so far unclear reasons.
