It's a russian victory when a family that couldn't leave freezes to death in the cold. Every Ukrainian family you keep alive is a victory against the russians. Personally I choose to support the civilians but very much support the military in my heart.

If you head to r/Ukraine there's a list of vetted charities one being a program that provides stoves to those trying to survive the cold. If you're not comfortable donating to the military, there are plenty of non combat programs to support.

There would just be a power vacuum and not much would change for the people of North Korea unfortunately.
