So, Trump goes to Davos and ends up announcing he won't be attacking Greenland, won't be putting tariffs on Europe, he has struck a forever/infinity deal (or the concept of a deal rather) that he has no details about and appears to no longer need to own Greenland. Which one day before he said he absolutely had to own for the security of the United States. 

Whatever could have changed his mind? 

This is probably going to be another one of those things where he hopes everybody forgets he did all this and then pretends he never said any of it and that he created the greatest deal with Greenland and Denmark in the history of the world. 

I guess we will just have to add Denmark and Greenland to the list of people Trump claims nobody has done more for than him. He's got a really long list. 

Putin's disappointed because nobody wanted Trump to takeover Greenland more than Vlad. 

In the meantime, he can go back to killing mothers, gassing people, and yanking grandpas out of their houses in the dead of winter in their underwear in Minnesota and maybe kidnap someone from Cuba or Canada.
