totalitarian government who has been murdering them, in violation of established international accords, for 8 years.

This is the most idiotic narrative.

The war was started by Putin's "countrymen" from Russia (especially Strelkov, openly and proudly: https://www.themoscowtimes.com/2014/11/21/russias-igor-strelkov-i-am-responsible-for-war-in-eastern-ukraine-a41598), and in the last several years almost everyone "murdered" in it was sitting in their respective trenches among abandoned villages, occasionally sniping at each other. There were practically no civilian casualties except from old unexploded munitions and mines, and even with these there were usually just injuries any given month if not just nothing at all.

Poroshenko was so "totalitarian" that he was voted out of office without trouble after 1 term in normal elections, exiled, and then put on trial for high treason (namely for dealing with the separatists, like buying coal from them and thus financing the enemy). They also took his personal assets. Totally totalitarian.

Now, who told you this crap originally, and why do you just believe them like that?
