I'm not reading every article you posted cuz I have a life, but this random one I clicked says this

To be clear, the Kremlin’s claims that Ukraine is a hornets’ nest of fascists are false: far-right parties performed poorly in Ukraine’s last parliamentary elections, and Ukrainians reacted with alarm to the National Militia’s demonstration in Kiev.

Yeah, there are neo-nazi fascists in Ukraine. And almost every other country on earth. They have a problem, and the war with Russia made it more difficult for them to deal with it. But unless you can't point me to one article (instead of listing a dozen at a time for some reason) that indicates it's backed by the Ukrainian government, then I don't see why the Ukrainian flag should be included in this meme. The US flag, sure, it looks like one of the articles is suggesting the US has supported fascists in Ukraine. But not Ukraine itself, and Russia is absolutely not invading to defeat the neo-nazis in Ukraine. Especially since Putin has been a textbook fascist since he took office and has barely tried to hide it.
