It's hard to think of any military intervention in the last 60 years by US and their friends that left the region or country in a better state, Asia, South-America, Africa, Middle-east it all became big mess. Arguable some of that mess was by design, but not all.

Russia is not something anyone can solve from the outside; they have to figure it out themselves. Same for the Europe & the US, there are enough things to figure out here.
