Last thing I'll say here for now: My friend just made these points:
OSCE said that Russians have transported weapons to Donbass
Russian media has confirmed there are Russian volunteers/mercenaries fighting in Donbass - my own point -> if Putin didn't want that, they would not do it...how many Russian citizens defy Putin so easily?
population of territories controlled by separatists is about 4 million people. The population of Ukraine is about 40 million people now.
So, Donbass armies can keep making the Ukr army retreat repeadedly? Without any assistance? Russians that support the rebels have not answered these questions sufficiently....they just turn around and make a complaint about Ukraine. I think they are separate topics.
Lastly, Russian soldiers rarely speak up about it - they fear losing their benefits...
