The Ukrainians are victims in all this. I’m sure they’ve experienced the whole range of emotions from patriotism, bravery, fear, anger, confusion. Turn our anger against those who profit from war.
As for people who go and join other people’s wars I’m a bit let charitable. I’m sure there’s some good intention there, but a lot of weirdos and psychos too who feel they are missing out if they’ve never been in a war.
