What will happen if at the end Russia succeed in her conquest against Ukraine and take over the economy of Ukraine. That will extend the economic power of Russia no doubt and that will make Russia more powerful.
How will EU and NATO countries relate with Russia if that happens ?
The economy of Ukraine is in ruins and the number of refugees exceeded 1 million(it will grow even further).
Even if Russia occupied Ukraine,there's going to be a gorilla war.Who is going to invest and build businesses in a country,that is ruined by a war and the people are trying to escape?
Ukraine will become a huge financial burden for Russia.Putin knows that and he doesn't want to conquer Ukraine.He wants to establish a puppet government and a guarantee that Ukraine will never become a member of NATO.
The economy of Russia cannot grow under severe western sanctions.
