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's 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.

Trump has goaded other allies, again suggesting a merger with Canada on the day when his liberal opposite to the north, Justin Trudeau, announced his resignation. Meanwhile, Trump vexed his neighbour to the south by saying he wants to rename the Gulf of Mexico as the Gulf of America. How do the Trudeaus of this world react?

Beyond performative politics, what is it all about? Is the man who wants a Ukraine deal on Day One an isolationist or an imperialist at heart? What sets him apart from his Russian and Chinese counterparts?
