After the Soviet Union’s murderous 50 year reign of terror over the poor Ukrainians, I don’t think their justified hatred of the Russians has or will ever fade.
What is interesting is that there are many in main part of Ukraine (not the heavy Soviet East) that miss the days of the USSR and unity with Russia. I have a friend that just earlier this year spent three weeks there and the family he visited with was very much that way and they were not alone. He was astounded at first and went into great depth to make sure he understood their longing for the lost regime and its stability.
