Ethnic cleansings in those territories are a fabricated casus beli for Russia 'green man'.
there have been reports of Ukranian paramilitaries shelling the Donbas going back almost a decade. multiple peace treaties were signed over it, all aiming to stop the ethnic cleansing. each and every one of those treaties were violated. this is all extremely well-documented. can you even prove that a single of these reports is fabricated?
