Any perspectives on the life of Russian psychic Wolf Messing?

https://en.wikipedia.org/wiki/Wolf_Messing https://en.wikipedia.org/wiki/Wolf_Messing:_Who_Saw_through_Time https://www.youtube.com/watch?v=aKOWiIAmTMQ I've been watching an excellent Russian television series on the life of psychic Wolf Messing, famous for, among other things, predicting the death of Hitler if he "made war against the east", and for being a personal acquaintance of Josef Stalin. I was wondering if anyone had any particular insights regarding this rather uniquely charismatic psychic performer. Was he a charlatan? Did he genuinely have the power to manipulate and read people's minds? Could he really predict the future? Any thoughts or observations on this rather remarkable twentieth century specialist in the paranormal?
