@ChrisMayLA6 It is all really simple. Trump wants to become immortal, and what better way than to get a peace prize (didn't work out) or to expand the country á la Putin? It is also interesting to note that all what he wants, control of ports, minerals, etc. he could get from Denmark just by bargaining for a deal.
But how will he proceed? I think he will push the greenland opposition to have an unofficial vote that will end up in favour of joining the US. To sweeten the deal, he will offer every greenlandet 500k-1 million dollars.
After the vote, he will just simply move in troops, companies, personnel and that's it.
What Denmark should do, is to let greenland quickly vote, as fast as possible, and this will result in a "no" against joining the US, a "yes" when it comes to increased independence of greenland, and this will become the "ethical shield" of denmark and greenland and make life more difficult for Trump.
At the end of the day, with such a vote, it doesn't matter if Trump moves in military and companies. In 3 years, the democrats will most likely win, and the troops will be removed, and the companies will stay and pay tax on greenland. Greenland will have become more independent, and all will be well.
