Ukrainian history did not started in 1991.
For all that Stalin, Khrushchev and other commies did to Ukrainians, they earned every bit of Ukrainian hate.
What you did not mention is that Ukrainians supported Nazis in WWII, and that just might be a reason why Russians treated them way they did.
Your "short version of their history" is what you can hear whole day, every day from MSM talking heads. So spare me of your "I couldn't live with myself if our country did nothing to help the Ukrainians" because their dirty as much the Russians are.
So, it's not even a trick question, and it's much harder not to answer it. If Ukrainians were doing the same things to Russians, would you be able to live with yourself if we don't help Russians?
