President-elect Donald Trump is the king of not ruling things out. It’s his default response when a possibility, no matter how far-fetched, gets floated, both because he has little regard for norms and because he seems to view extreme ideas as negotiating ploys.

President-elect Donald Trump left open the possibility Tuesday that he might use military force to take over the Panama Canal and force Denmark to sell Greenland to the United States, and said he could use “economic force” to make good on his bizarre proposition of annexing Canada.
