Another Russian here. I don't agree and don't support this action.
We anticipate long years if not decades of isolation, even more stagnating economy, even more authoritarian government. By all means it's a terrible thing.
For both Russians and Ucrainians alike.
But... The drama around it as portrayed in Western media is ridiculous. There won't be major loss of life nor any "war" in conventional sense. It would be no more war than it was in Crimea in 2014.
I don't justify. It's a political disaster but not a humanitarian one.
