I spend a lot of time on twitter in order to post things about Ukraine

I'm not going to post the tweet but it's from a guy in the UK called Jimmy, very knowledgeable, pro Ukraine.
He says there is a video circulating of a Russian castrating a Ukrainian prisoner. And he reports it's happened on other occasions.
I can't take anymore for now. I'm going to take a break.
I don't understand why we haven't done what's necessary to win this war.
