How about simply:
1. Burning his body.
2. Changing the name of Leningrad back to whatever it was called before that maggot rose to power.
3. Changing the history Russian history books to portray Lenin and all of his friends and successors as the evil slavemasters they were/are.
That was done 20 years ago. Since then, it is now again called St. Petersburg.
Regards,
Leningrad used to be St Petersburg. It is being called that again.
