Okay, you’re sort if correct. He alluded to it. He mentioned the Russian Empire attacking various neighbors and taking over their territory using excuses of ethnicity and then referred to it as returning and reinforcing, not conquering. He then said it fell to their lot to return and reinforce, as well. Here’s a link that discusses it. Given the date and the discussion, I’m sure you can find other sources for it. That was just the first that appeared on my search.
There’s no evidence that what feels good to you actually reduces the odds of the perpetrator committing crimes again or reduces the rate of those crimes in society in general, and good evidence that what doesn’t feel good to you does those things. So you will have to decide if you would rather feel good about how the person who did something wrong was punished or have less crime in your society.
