The narrative for this has already been set in the West. Most people only take in the headlines of what's right under their noses. Here is what English speaking people, and Europeans now believe:
Euromaidan were freedom fighters who overthrew a Moscow puppet dictator
Russia invaded Crimea militarily against the will of many in the population, after a fake/rigged referendum.
Everything bad that happened since then, particlularly in the East, is Russia's fault.
The Eastern rebels are terrorists supported logistically from Moscow.
Putin is doing this due to "Russian imperialism" and/or dreams about resurrecting the USSR.
All this proves Russia is a threat to Europe and must be stopped from meddling in other countries.
