Lies about Stalin and sources to debunk them?

Due to his significant contributions to communism, especially the fall of the nazis at the hands of the Soviet Union's Red Army, Stalin is one of the most vilified names in history. From western leftists to fascists, they are quick to paint him as an irredeemable monster.

Therefore, I would like to ask you, dear comrades, if you know any good sources to debunk the many lies about Stalin. I would also appreciate if you could include the claims made by Khrushchev and sources to debunk them.

Cheers
