If you want to believe that Russia had no military forces in Ukraine before 2022, then I have a bridge to sell you.
Or do you think Russia is in the habit of randomly transporting air defense systems with Russian crew through different nation-states they have nothing to do with? https://en.wikipedia.org/wiki/Malaysia_Airlines_Flight_17#Fi...

that's not what i said, and supporting a warring faction doesn't really qualify as "invasion" nor "taking territory".
also, i would recommend very strict skepticism about politically sensitive content on wikipedia. it can still be useful for general timelines, but a simple check at the sources (when there are any) will reveal they tend to be overwhelmingly one-sided.
it's fine if you want to learn about, say, birds, engines or stars, though.
