Gromit it is nonsensical, even outrageous, effectively to blame the EU for the conflict in Ukraine. Closer ties with the west are what the majority of people in Ukraine want, not because they love the EU, Mr Juncker, Brussels, Strasbourg or any of that, but because they are attracted by many of the standards the EU demand of countries which want to join it.
This includes things like a fair judiciary, not the basket case of a justice system which has existed hitherto, where "justice" depends on how much you bribe a judge. Moscow was able successfully to scare the criminal ex-president Yanukovych away from the EU deal because the pointed out to him, rightly, that yes, he could embezzle billions of dollars of the hand out money, but he'd have to front up on corruption and cronyism. An irreconcilable dilemma.
So if you really want to deflect the blame from Russia for more or less 100% of what has happened since (and good luck with that) then blame the students, lawyers etc of the Maidan movement who took on a corrupt government and won.
