My choice would be Putin.
Sure Trump would be great to a have a deep discussion with.
But, Putin comes from a completely different perpective. Not saying he is a good person. Background in the kgb doesn't paint a rosy picture. But, he has been in power for a long time and has seen it all.
I think Putin has dirt on so many that I despise. He could tell us all about hillary and barry. He has the goods on ukraine and the biolabs. He likely could tell us all about epstein and who epstein owns. And on and on.
Lastly, he seems to be fighting the globalists, is he a changed man or just fighting a common enemy?
I like your choice, would be quite the history lesson.
