you forgot about 2004 maidan, american pressure which followed and yuschenko's 4 years. he did a lot to put the seeds to antagonize people. the spread of holodomor(purely political action by hohol government) with transparent goal to equalize russia as a whole with it. building monument about military victories against russia, and making it holidays. bandera and oun upa glorification and official whitewashing, sending anti air weapons to georgia prior to georgian war against ossetia(which was against russo-ukrainian friendship treaty) because ossetia had no air force. weapons would be used to kill russians. making joining nato into official main directive of ukraine foreign policy. etc. all in accord with american 2004 plan of nato expansion. this all was started by him, american creatura. russia was chill about ukraine, until all that clear hijack happened with nato joining directives.
