Fake news
Not really US Govt documents. They a series of posting on a Russian proapganda website claiming to be US Govt Documents
Russian Goverment disinforamtion, not real.
Do not be so sure that it is all false. There were A LOT of articles on Bio research in Ukraine before this event started. I see it as Putin capitalizing on it to obviously support his cease but that doe snot make it untrue.
Do not fall into the trap of assuming it must be untrue because the enemy is using the information in support of their agenda.
