What makes communism so dangerous is that it combines fanaticism with modern technology. Similar to fascism but very unlike religious fanaticism which seems to advocate low tech approach.Communism can brainwash the people, ok, but is it not the same in fascism, religious fanaticism or other things?
Ukraine army will win. It needs resolve, discipline, endurance and weapons. I have sympathy for underdogs. This war is unjustified, unprovoked.
I don’t think anyone that follows the world liberal order will fight to the same level as a brainwashed communist of fascist.
