You will have to translate this German language article, but this is NOT Trump. It is about the tech billionaires supporting this quest, and why they want it.

I doubt Trump would have ever even thought of Greenland on his own. I think was told about it, and the narrative planted in his head deliberately.

This focus on "Trump" in Internet comments and media irks me to no end. Trump is not a failure and not the wrong person in the job - he is ideal for those behind him. The money does not like public attention.
