We don't need a Russian leader who is actually anti-war. 
Just one that's smart enough to admit they have lost this one and willing to play the part of a Russia asking for forgiveness and removal of sanctions. 
They will probably also start work on re-arming and modernising the Russian Military in preparation for the next war. But it would still be an improvement on the current situation.

It would have to be another Russian though.  They haven't really excelled when it comes to picking types of governments.
