> If you want to believe that Russia had no military forces in Ukraine before 2022
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.
The European Court of Human Rights (ECHR) has established that there was no genuine separatism in Eastern Ukraine in 2014. From the get-go, these were operatives of Russian military and special services, or people under their direct control. Girkin, one of the main leaders of Russian forces in Ukraine, has confirmed the same: there was no grassroots action; it was them who started the war in 2014. Removing insignia from uniforms does not make it any less of a foreign invasion.
ECHR's lengthy verdict on the responsibility of the MH-17 shootdown lays out all the relevant facts.

Doing so with active duty military forces absolutely does.
