> So Putin has quite literally achieved nothing.

If he achieved "nothing" that would infact be preferable for Russia to the state they are in now. What he did is an equivalent of the manager of your team pulling a couple of all nighters over the weekend to do a "hero-refactor" on your codebase for "improvements" and then deploying it into production only for everyone to discover that the "improved" code has massive performance regressions, worse user experience and is harder to maintain... worse it can't be rolled back easily and the process of rolling it back will be slow and annoying, that is if the manager who made those changes even admits that it should be rolled back in the first place.
