War is a destructive force and in the current age it shows great weakness, at least when you do it in a way that Russia has done - attacking a direct neighbor, but not being able to punch a decisive throw and now deteriorating their own economy every single day it continues. You could say it was inevitable, as Putin  becomes a weaker old man every day, he wanted this one last flex to try and claw back something for Russia, but we he falls - and he will - it will all go back to Ukraine and this whole affair will have been a colossal waste for both sides - plus Russia has made an enemy for a very long time that will never want to trade with them again in future and will do everything to undermine them
