I kind looked at it as Putin getting rid of old stock...and Ukraine has to spend the time and manpower to clean it up.
If mankind could only develop ways to improve the world as good as they do destroying it we might have a better place to live.
Of course. The Russians are spending all the time and supplies on that "old stock", which also happens to be crewed by Russian soldiers who are killed during that Ukrainians "clean up".
That sounds kind of like trying to break the other guy's fist with your face.
