Zelensky is doing wonderful job using nationalists to fight the Russians 👏 . You can think of this as payback for genocide committed by Ukrainian nationalists (members of OUN-UPA) on: Jews, Poles, Belarusians, Russians,.... This should help. Is there a downside when Ukrainians and Russians knock each other off?
Don't forget all of the civilian Poles slaughter by the Ukes in the 1930's
