Fortunately, that's made up nonsense, which the Russians have never presented any real evidence for (other than showing photos of schools that, it turned out, were in Ukrainian controlled settlements that the Russians themselves were bombing). You can post the evidence yourself, if I am wrong (and no, posting posts from Telegram is not "evidence" of anything).
Meanwhile, there are dead bodies, maimings, destroyed homes, on a nearly daily basis documented by the OSCE from Russian terror attacks on civilian targets since 2014 to the present day, which they would accuse Ukraine of either doing to themselves or denying altogether. Not to mention huge numbers of Russian troops, artillery and other elements filmed/documented by the OSCE, which the Russians wouldn't even admit were there.
Not surprising for the country that trained/supported Yasser Arafat and the PLO and invented modern terrorism, eh?
Terrorism has always been a useful tool for the US/UK/NATO.
Your point fails miserably.
