Putin had an uptick in profits from oil. But what were his achievements during the 20 years of his dictatorship?
He organized a group of his cronies who privatized the wealth that supposed to belong to the whole country. If it was his plan (it probably was) then he succeded in it.
He understood that there could be people in the country who would not like his and his cronies behaviour. So he took measures to bribe or intimidate or kill that people. He succeeded with this too.
So his successes are only related to the actions aimed at personal enrichment and enrichment of his cronies.
Putin spent a lot of money for subversive work in other countries. Traditionally the russian state used to harm the West. In this regard, putin turned out to be the most persistent and purposeful.
Has he tried to change the structure of the Russian economy in order to reduce dependence on the sale of hydrocarbons?
He has not.
On the contrary, he developed only this extraction, eliminating free business.
When a lot of people in russia still do not have a modern amenities like running water, gas, canalization and so on - it is a shame for the leader.
He has made the Russian federation open to be cut up by a resurgent China
