Why does trump want to buy Greenland?

The Sun is global warming. He wants to exploit it to harvest Greenland's hidden resources. 6 of Pentacles feels like transferring wealth from them to him. Column 1 feels like him fighting them because they rejected his offer. Not much else to say. We all knew this is what it was. It doesn't show the influences behind it, just that he's after exploitation and a transfer of wealth via untapped resources.
