Lenin recovered from his second stroke enough to investigate the Georgia matter himself before suffering his third stroke and dying. You make it sound like Lenin was warning the world of the evils of Stalin on his deathbed, and that's just not what happened.
And Stalin and Lenin had been colleagues and friends for twenty years by this time. They knew each other since 1905. And was he not in prison for working on the revolutionary socialist project?
And I apologize for being rude, but this is just contrary to everything I've learned about Stalin. Frankly, it feels indistinguishable from liberal histories of Stalin, which have been extremely falsified. So when I say you've been mislead in a serious way, I'm being quite serious.
