I just spent a month in Kyiv. The reason why I can do that is because Ukrainian soldiers are keeping back psychopathic Russians who would otherwise invade and destroy the city.
Those Russians I helped kill would have otherwise killed those Ukrainian soldiers keeping me safe and making it positive for me to be in Kyiv.
This isn't some abstract "war machine" nonsense. This is killing dangerous, evil, men who want to kill me and my friends.
I've been in Kyiv many times during air raids with Russian shahed drones flying around. I've seen first hand them hitting civilians in their apartment buildings. I've also seen Russian propaganda footage of the Russians building those shaheds.
If I had the chance, I would happily kill every last one of those Russians. Without a doubt.
