The Wagners in Syria were mercenaries not RF troops and a good number were Ukrainians
That's interesting. The Ukrainians didn't wake up hating the Russians one day, did they. I mean there were a lot of Russian speaking Ukrainians who thought of themselves as Russian-speaking Ukrainians, not Russians trapped in Ukraine.
At least that's my impression. So, it's not surprising there were Ukrainians fighting with Wagner, or even in the Russian Army a while ago.
There was a process: a breakdown of civility.
It takes time to build hatred like this.
