Russia will never let Ukraine be a member of NATO. Not after the war, never.
Russians had a song once.
An unbreakable union of free republics,
Great Russia has been sealed forever.
That "unbreakable" and "forever" didn't work out for them.
Just very recently they declared Kherson as part of Russia and put up billboards saying "Russia is here forever. They were kicked out a little over a month later.
