He didn't take over the USSR, he took over the Russian Federation, which is very different. He overthrew a "democracy" as the US called it as part of the FSB.
I would advise to watch some content with Putin speaking. A hell more intelligent and constructive than most US presidents. Russia is very power fragile country. It requires a very strict setup to hold stability. Lots of western countries (specially the US) are trying to break the stability by supporting lunatics which we in the west call the opposition. Those lunatics have one single mission and that is to destabilise or sabotage the Russian society. I will never say it's right to simply murder your opponents. But currently the country is very stable, safe and economically made enormous steps last 20 years. Leadership in Russia is very strong. It has still many issues to resolve. But please can the west stop enforcing their so called 'freedom' setup in non democratic countries.
Yes, many do not realize that Putin is quite intelligent or the complexities of the Russian state that could cause some unfortunate power struggles without Putin.
However, you're completely glossing over why Western countries have such problems with Putin. Do you have evidence of the West "enforcing" their ideals with the Russian state? Because here are a list of practically doubtless examples of the Russian state actually being the one enforcing their ideals onto other states:
Poisonings / assassination attempts outside their borders
