General Discussion

Trump's role is to be the carnival barker that (apparently) half the U.S. population enjoys watching.

I doubt most of his policies and actions are his ideas. Other people tell him what to do. Notably, he does what Putin tells him to do because Putin owns him. Trump is also owned by several South African billionaires. And he's owned by China.

What do one or more of those entities get out of Trump's obsession with Greenland? Chaos? Destabilization of western allies? Distraction? A genuine interest in controlling Greenland? Russia taunting Denmark?
