Putin is not the good guy but neither is Zelensky. Ukraine is as corrupt as a country can be and is only marginally better than Russia. Ukrainian officials aren’t interested in gaining territory like Putin is, they just want giant piles of money. Putin REALLY wants the farmland that is Ukraine since Russia can’t grow enough food.
Nobody is fighting to support corruption or Zelensky.
Ukrainians are fighting to be free from Putin/Russian brutal domination and to have the freedom to choose their own future.
