The videos from this guy provide insights into the mentality that has prevailed leading up to the war. Plainly, the Russians have been horribly brainwashed (along with their stooges).
I am Finnish and Finns have a word "sisu" that means the ultimate in strength and determination. I have a tattoo on my arm to remind me. That's what took the Finns through the Winter War with Russia in 1939. The Ukrainian people definitely have SISU. My thoughts are with them.
