I am not accepting Russian sources for my belief.
Our current regime first stated we supported no labs in Ukraine and then later changed the story to admit we funded “medical research” in Ukraine as normal cooperation between civilized governments.
So first a denial then changed the story to something more palpable for the masses.
Next I considered how our government previously lied about covid. Honestly, just those two positions is enough to give reasonable cause to be suspicious of our activities in Ukraine. Are you ready to defend Fauci and all the lies about covid? That is the basis for my skepticism now.
As I see it Occam’s Razor in this case would point to the likely possibility we did indeed have such labs in Ukraine. I base it not on Russian, Ukraine or US propaganda. I base it on my review of all that material I have considered to this point and find it most likely Russia and Ukraine are bad actors and the US did have some kind of military bio research occurring in Ukraine.
So first a denial then changed the story to something more palpable for the masses.
US has ALWAYS denied "bio-weapons labs" in Ukraine.
The bio labs supported in Ukraine (and many former Soviet Countries) is part of the Nunn–Lugar Cooperative Threat Reduction which is common knowledge.
