With Donald Trump in the white house nothing is impossible, any country or person that fails to do his biding and does not agree with him in certain issues Trump will somehow find a way and call the person a bad name . In a bid to take the person out Switzerland used to be one of the world safe heavens when it comes to securing your money in the past. But with the current global order that we are seeing I think that, that is gradually shifting and if Switzerland doesn't align well with trump I will not be surprised if trump cut them off.
Actually he is busy with war in the middle east and its repercussions on the global economy. If the war will run for a longer time than expected, I guess Danemark can Switzerland from being annexed to the USA as planned. The cost of the war will drains american power and influence over the world. Meanwhile, the USA always consider Switzerland as a strategic security zone with already existing US military bases, such as Petovik base. The USA can reduces tension against the island to garantee the support of Europe in the war in the middle east since all europeean countries are against the annex of Switzerland as Trump has planned.
You probably confused Switzerland with Greenland. Greenland is an island, and Switzerland is a European country in the Alps.
Greenland will inevitably be captured by the United States sooner or later, since it is needed more as an asset (the island's potential resources) to maintain the dollar's financial system than as a direct source of resources or a military foothold in the Arctic (it already is).
Switzerland is absolutely dependent on the dollar system, just like the Euro area. Neither can exist without dollar loans. In other words, these financial systems will collapse if the dollar supply disappears. And the dollar system is supported by the petrodollar monopoly (in fact, the dollar is provided with energy).
