If you had followed what has happened in Ukraine since 2014 you must know there was a coup instigated by America supported by the EU, the legal elected government of Yanukovych was overthrown Porochenko then declared war on his own citizens in Dombass because they didn't support the Coup, ethnic Russians were attacked and killed Cities like Donetsk were shelled with many civilians killed anti Maidan protesters were burned alive some beaten to death in Odessa by a Fascist mob and Porochenko turned the army and Nazi gangs like Azov and Tornado loose on the people in Donbass, so the ethnic Russians got organised and fought back and taught the Ukrainians a lesson, meanwhile the Maidan leadership would have given the Russian naval base in Sebastopol to NATO where the Russian Black Sea Fleet was based, now if they thought Russia would tolerate that they should have had their heads tested, mistake Russia made was waiting until 2022 to go in, they should have done it in 2014, as for Russia in 1918 there was a revolution against the Monarchy not against any sort of Democracy which was a totally different situation and not the business of those Western Countries who intervened to stop the revolution, now that is a brief history of those events not an opinion but facts not some alternative reality in your head
