Right now? Nothing.
Russia had already prepared itself for a Western departure, the sanctions just pushed them more decisively to the East. Europe will have to live with the long-term consequences of having an unfriendly neighbor after the bad geopolitical choices they made, a consequence of overestimating their bargaining power.
That regime change wouldn’t happen in Russia as a consequence of sanctions was always obvious, but people just wanted to repeat what made them feel better even if it had no connection with reality lol
40% of Europe is in Russia, so Russia is not a neighbor to Europe they're a very big part of it. If you're talking about the EU Russia was already an unfriendly neighbor and they made the choice of trying to destabilize neighboring countries like Georgia, Ukraine and Moldova rather than giving them a choice to freely associate with the West and scaremongering about NATO, a defensive alliance they had nothing to fear from. Russia turning towards China was more or less inevitable and will only be reversed when the Westernized generation within the elite who are now in their 30s get into power.
