So, you're saying the US (300+ mln, #1 military) never actually requested to deploy them and Denmark (5 mln) never actually refused. But because you think an agreement is unlikely, it's straight to annexation by force. Do I have that right?

No, I'm saying that new military installations would be unlikely to be agreed due to domestic political sentiment. Pituffik was certainly agreed by both sides, but that was a long time ago.

(I'm not Danish or Greenlandic, so this is just my reading of the situation.)
