Russian aggression was going on even before the fall of Yanukovych, although it was political, not military. The Maidan rebellion was response to that aggression. Whatever its causes, however, this does not justify Russia's invasion in 2014. The internal politics of Ukraine were the Ukrainian's to settle, not Russia. In any case, the events of 2014 cannot be used to justify Russia's second invasion in 2022. There were two national elections since then. The conflicts that arose in 2014 could have been resolved peacefully by the Ukrainians if the Russians had not intervened.
Actually, no.
The government we toppled was on good terms with Russia and by Hillary THAT COULD NOT STAND, so oops, Maidan Coup.
And where did that get us?
Untold thousands dead, Zelensky tweaking on TV, and people online drumming for another pointless war we have no business being involved in.
