“Dear Jonas,” the president wrote to Norway’s prime minister, Jonas Gahr Støre. “Considering your Country decided not to give me the Nobel Peace Prize for having stopped 8 Wars PLUS, I no longer feel an obligation to think purely of Peace, although it will always be predominant, but can now think about what is good and proper for the United States of America. Denmark cannot protect that land from Russia or China, and why do they have a ‘right of ownership’ anyway? There are no written documents, it’s only that a boat landed there hundreds of years ago, but we had boats landing there, also. I have done more for NATO than any other person since its founding, and now, NATO should do something for the United States. The World is not secure unless we have Complete and Total Control of Greenland. Thank you! President DJT.”
He has pretty much torched all of the USA’s soft power and standing as a trade partner.
GWB had already done some damage to both, which Obama tried to repair (more so on the trade front). Then Trump I happened and made it very clear that the USA were no longer a reliable partner and probably not even politically stable in the medium term. Biden tried to salvage something but then Trump II happened and conclusively buried what little goodwill the States had left.
I don’t think the pax americana is going to survive the decade and neither is the petrodollar. It remains to be seen whether the States will become a local hegemonial power, a failed empire with lasting ambitions á la Russia, or will even fade from relevancy entirely. I don’t expect them to remain a superpower.
The way he’s pushing his shit, I’d be surprised if the states are still united bè the end of the decade.
