I think that is just a rationalization for staying away from the conflict. I doubt you would apply that same kind of thinking to any other situation where one party was attacking another.
If you saw some kid getting attacked in the parking lot of a Walmart would your response depend on whether or not you thought there might be some corrupt people living in that town?
Even if there are many corrupt Ukrainian politicians and rich businessmen, that doesn't justify ignoring an attack against everyone in the society, including innocent children and others who have nothing to do with any corruption.

The fact you think this is an equivocal metaphor for yet another ethnic feud between Slavs is simply ludicrous.
