To answer that question you need to know what goes on inside the head of a bona fide narcissist and “drama queen” - both Cluster B conditions of character dysfunctions.
Narcissists have an ego beyond compare, They see themselves as entitled to all possible attention. As “drama queens” they are extremely sensitive of everything that can work to their disadvantage, even harmless things that people around them are hardly aware of. They tend to see themselves as victims of dangerous conspiracies, even when there are none.
Drama queens never forget what they once perceived as an injustice. A narcissist can be dangerously vindictive.
To the core of the question: Greenland. Trump the narcissist thought that he could buy Greenland from Denmark. That would satisfy his narcissist ego. He would be famous and every American would thank him for it and admire him for such a brilliant initiative.
In stead the danish prime minister chuckled the question away, stating that this was “absurd”. This stings directly into the heart of a drama queen. And it adds shame to injury that the PM laughing at him is a woman!
The story becomes known in the media and goes viral. Even greater humiliation of the drama queen.
Burning desire for retaliation. Trump wins the 2024 election and is back at the helm. He wants Greenland! The humiliation is not forgotten. Time for retaliation. He will show that lousy b—ch who has the last word!
He repeats his ambition. But this time with threats of invading Greenland if it is not given to him. He starts preparations for taking the control. He sends his son to prepare the takeover. Some homeless people are rounded up, given MAGA hats and promised a free meal if they will cheer in front of the cameras for the idea of USA taking control of Greenland.
But this primitive rough hewn imperialism is not enough. He also needs rational reasons for bullying Denmark to give Greenland to him. (Note: Greenland shall be given to HIM, Donald - not to USA even if they will be the new “owners”).
First he comes up with reasons of security. What danger is Greenland in? The greatest threat to the security of Greenland is the USA!
He is on a roll now, he cannot stop: He wants Canada as well. Somebody tells him that is hardly possible. He needs more reasons: Tariffs! He can force tariffs upon Canada, That will teach them to laugh at him in front of the cameras at the G7 meeting where Justin Trudeau and some other state leaders chuckled at his stupidity and ignorance.
Canada also needs to be thought a lesson. And Panama.
And suddenly he cannot stop. All the world shall be subdued by tariffs. In his narcissistic mind he thinks that USA (as an extension of his ego) has a natural right to block all nations that has a trade surplus with the US from running that surplus.
Even Rupert Murdoch, his high protector and supporter has to call BS on what he is up to. Murdoch may be far into the twilight zone of fascism, but he understands economics and he can see where Trump is heading.
Without going via his editors, he stands on the front page of his own newspaper - Wall Street Journal - stating, in his own words that “This is the dumbest trade war ever”.
How can Trump, the narcissist and drama queen digest that?
Opinion polls show that 6% of the Greenlanders are positive to being ruled by the US. 85% are vehemently against!
Trump promised the oil industry everything they wanted if they would donate 1 billion dollars to his campaign. He won the election and during the campaign he added another mantra to his slogans: “Drill-baby-drill”.
Was full access to oil and mineral explorations on Greenland included in that deal?
Trump has to make a humiliating 180 degree turn. The stock markets are tanking at his trade wars. Denmark is gathering political and military support for defending Greenland. The Canadians are booing when the US anthem is being played at sports events and Canadian leaders are promising full fight, if that is what Trump wants.
Mark Carney, a brilliant economist with international experience is favourite to become the next prime minister of Canada. There is no one in the Trump staff and cabinet that can match Carney if it comes to the intricacies of international trade.
It is absolutely no chance that Trump is able to comprehend what problems he is causing for the American people.
Greenland will remain a part of the kingdom of Denmark,. There will be discussions in Greenland and between Greenland and Denmark over what Denmark can to better for Greenland.
But Tump will drag USA into the most humiliating political defeat since they lost the Vietnam war.
