Is he serious? Allies wary as Trump threatens Greenland, Panama, Canada

Imagine if Vladimir Putin or Xi Jinping threatened a hostile takeover of Greenland or the Panama Canal.

So what about the president-elect of the United States… Is Donald Trump serious? Trump whose growing fixation comes two weeks ahead of Inauguration Day. He even sent his son to Greenland, much to the dismay of Denmark. That EU member has ruled Greenland for two centuries. Today it needs US-led Nato support to stare down the more pressing threat of the Russians in the Baltic Sea.
